  • How should I change my Graph structure (very slow insertion)?

    - by Nazgulled
    Hi, This program I'm doing is about a social network, which means there are users and their profiles. The profiles structure is UserProfile. Now, there are various possible Graph implementations and I don't think I'm using the best one. I have a Graph structure and inside, there's a pointer to a linked list of type Vertex. Each Vertex element has a value, a pointer to the next Vertex and a pointer to a linked list of type Edge. Each Edge element has a value (so I can define weights and whatever it's needed), a pointer to the next Edge and a pointer to the Vertex owner. I have a 2 sample files with data to process (in CSV style) and insert into the Graph. The first one is the user data (one user per line); the second one is the user relations (for the graph). The first file is quickly inserted into the graph cause I always insert at the head and there's like ~18000 users. The second file takes ages but I still insert the edges at the head. The file has about ~520000 lines of user relations and takes between 13-15mins to insert into the Graph. I made a quick test and reading the data is pretty quickly, instantaneously really. The problem is in the insertion. This problem exists because I have a Graph implemented with linked lists for the vertices. Every time I need to insert a relation, I need to lookup for 2 vertices, so I can link them together. This is the problem... Doing this for ~520000 relations, takes a while. How should I solve this? Solution 1) Some people recommended me to implement the Graph (the vertices part) as an array instead of a linked list. This way I have direct access to every vertex and the insertion is probably going to drop considerably. But, I don't like the idea of allocating an array with [18000] elements. How practically is this? My sample data has ~18000, but what if I need much less or much more? The linked list approach has that flexibility, I can have whatever size I want as long as there's memory for it. But the array doesn't, how am I going to handle such situation? What are your suggestions? Using linked lists is good for space complexity but bad for time complexity. And using an array is good for time complexity but bad for space complexity. Any thoughts about this solution? Solution 2) This project also demands that I have some sort of data structures that allows quick lookup based on a name index and an ID index. For this I decided to use Hash Tables. My tables are implemented with separate chaining as collision resolution and when a load factor of 0.70 is reach, I normally recreate the table. I base the next table size on this http://planetmath.org/encyclopedia/GoodHashTablePrimes.html. Currently, both Hash Tables hold a pointer to the UserProfile instead of duplication the user profile itself. That would be stupid, changing data would require 3 changes and it's really dumb to do it that way. So I just save the pointer to the UserProfile. The same user profile pointer is also saved as value in each Graph Vertex. So, I have 3 data structures, one Graph and two Hash Tables and every single one of them point to the same exact UserProfile. The Graph structure will serve the purpose of finding the shortest path and stuff like that while the Hash Tables serve as quick index by name and ID. What I'm thinking to solve my Graph problem is to, instead of having the Hash Tables value point to the UserProfile, I point it to the corresponding Vertex. It's still a pointer, no more and no less space is used, I just change what I point to. Like this, I can easily and quickly lookup for each Vertex I need and link them together. This will insert the ~520000 relations pretty quickly. I thought of this solution because I already have the Hash Tables and I need to have them, then, why not take advantage of them for indexing the Graph vertices instead of the user profile? It's basically the same thing, I can still access the UserProfile pretty quickly, just go to the Vertex and then to the UserProfile. But, do you see any cons on this second solution against the first one? Or only pros that overpower the pros and cons on the first solution? Other Solution) If you have any other solution, I'm all ears. But please explain the pros and cons of that solution over the previous 2. I really don't have much time to be wasting with this right now, I need to move on with this project, so, if I'm doing to do such a change, I need to understand exactly what to change and if that's really the way to go. Hopefully no one fell asleep reading this and closed the browser, sorry for the big testament. But I really need to decide what to do about this and I really need to make a change. P.S: When answering my proposed solutions, please enumerate them as I did so I know exactly what are you talking about and don't confuse my self more than I already am.

  • Jquery fade and swap an element when clicked which will also relate to an accordian menu

    - by Nik
    You will notice when you click posture 1 the description drops down and images appear on the right. Now when you click posture 2 or posture 3 the images and description change as they should. What I need to do now is - If posture 1 has been clicked and then posture 2 is clicked the posture 1 menu needs to close so that there is only one posture description visible at one time. If I could also make it so that if the current open posture item is clicked so that it closes and there are no open posture descriptions that there also no images displayed on the right. Finally is there a way to make sure only one set of animation images is running, because just say the user goes through all 26 options and they continue to run in the background it may get sluggish (thanks to Nick Craver for bringing that up). At this stage only posture 1, 2 and 3 are available. Ok finally some code - //Description drop-down boxes $(document).ready(function(){ //Hide (Collapse) the toggle containers on load $(".toggle_container").hide(); //Switch the "Open" and "Close" state per click $("h5.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h5.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); //Images on the right fade in and out thanks to aSeptik $(document).ready(function(){ $('#section_Q_01,#section_Q_02,#section_Q_03').hide(); $(function() { $('h5.trigger a').click( function(e) { e.preventDefault(); var trigger_id = $(this).parent().attr('id'); //get id Q_## $('.current').removeClass('current').hide(); //add a class for easy access & hide $('#section_' + trigger_id).addClass('current').fadeIn(5000); //show clicked one }); }); }); //Fading pics $(document).ready(function(){ $('.pics').cycle({ fx: 'fade', speed: 2500 }); }); Description boxes - <h5 class="trigger" id="Q_01" ><a href="#">Posture 1 : Standing Deep Breathing :</a></h5> <div class="toggle_container" > <div class="block"> <span class="sc">Pranayama Series</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_02" ><a href="#">Posture 2 : Half Moon Pose With Hands To Feet Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Ardha Chandrasana with Pada-Hastasana</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_03" ><a href="#">Posture 3 : Awkward Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Utkatasana</span> <p class="bold">Benefits:</p> </div> </div> and the images on the right - <div id="section_Q_01" class="01"> <div class="pics"> <img src="../images/multi/poses/pose1/Pranayama._01.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._02.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._03.jpg"/> </div> </div> <div id="section_Q_02" class="02"> <div class="pics"> <img src="../images/multi/poses/pose2/Half_Moon_Pose_04.jpg" /> <img src="../images/multi/poses/pose2/Backward_Bending_05.jpg" /> <img src="../images/multi/poses/pose2/Hands_to_Feet_Pose_06.jpg" /> </div> </div> <div id="section_Q_03" class="03"> <div class="pics"> <img src="../images/multi/poses/pose3/Awkward_01.jpg" /> <img src="../images/multi/poses/pose3/Awkward_02.jpg" /> <img src="../images/multi/poses/pose3/Awkward_03.jpg" /> </div> </div> It would be a bonus if images faded out when another element is clicked... but not a big deal. Thanks for having a look

  • Gui problem after rewriting to MVC

    - by trevor_nise
    I'm practicing MVC style programming. I have a Mastermind game in a single file, working with no problems (maybe apart of the fact that "Check" button is invisible at start). http://paste.pocoo.org/show/226726/ But when I've rewritten it to model, view, controller files - when I click on empty Pin (that should be updated, and repainted with new color) - noting happens. Can anybody see any problems here ? I've tried placing repaint() in different places, but it simply does not work at all :/ Main : public class Main { public static void main(String[] args){ Model model = new Model(); View view = new View("Mastermind", 400, 590, model);

  • Why are my Opteron cores running at only 75% capacity each? (25% CPU idle)

    - by Tim Cooper
    We've just taken delivery of a powerful 32-core AMD Opteron server with 128Gb. We have 2 x 6272 CPU's with 16 cores each. We are running a big long-running java task on 30 threads. We have the NUMA optimisations for Linux and java turned on. Our Java threads are mainly using objects that are private to that thread, sometimes reading memory that other threads will be reading, and very very occasionally writing or locking shared objects. We can't explain why the CPU cores are 25% idle.

I had trouble finding a clear explanation of what 'top' means by "idle" versus "wait", but I get the impression that "idle" means "no more threads that need to be run" but this doesn't make sense in our case. We're using a "Executors.newFixedThreadPool(30)". There are a large number of tasks pending and each task lasts for 10 seconds or so. I suspect that the explanation requires a good understanding of NUMA. Is the "idle" state what you see when a CPU is waiting for a non-local access? If not, then what is the explanation?

  • Storing unique values into an array and comparing against a loop - PHP

    - by Aphex22
    I'm writing a PHP report which is designed to be exported purely as a CSV file, using commma delimiters. There are three columns relating to product_id, these three columns are as follows: SKU Parent / Child Parent SKU 12345 parent 12345 12345_1 child 12345 12345_2 child 12345 12345_3 child 12345 12345_4 child 12345 18099 parent 18099 18099_1 child 18099 Here's a link to the full CSV file: http://i.imgur.com/XELufRd.png At the moment the code looks like this: $sql = "select * from product WHERE on_amazon = 'on' AND active = 'on'"; $result = mysql_query($sql) or die ( mysql_error() );?> <? // set headers echo " Type, SKU, Parent / Child, Parent SKU, Product name, Manufacturer name, Gender, Product_description, Product price, Discount price, Quantity, Category, Photo 1, Photo 2, Photo 3, Photo 4, Photo 5, Photo 6, Photo 7, Photo 8, Color id, Color name, Size name <br> "; // load all stock while ($line = mysql_fetch_assoc($result) ) { ?> <?php // Loop through each possible size variation to see whether any of the quantity column has stock > 0 $con_size = array (35,355,36,37,375,38,385,39,395,40,405,41,415,42,425,43,435,44,445,45,455,46,465,47,475,48,485); $arrlength=count($con_size); for($x=0;$x<$arrlength;$x++) { // check if size is available if($line['quantity_c_size_'.$con_size[$x].'_chain'] > 0 ) { ?> <? echo 'Shoes'; ?>, <?=$line['product_id']?>, , , <?=$line['title']?>, <? $brand = $line['jys_brand']; echo ucfirst($brand); ?>, <? $gender = $line['category']; if ($gender == 'Mens') { echo 'H'; } else{ echo 'F'; } ?>, <?=preg_replace('/[^\da-z]/i', ' ', $line['amazon_desc']) ?>, <?=$line['price']?>, <?=$line['price']?>, <?=$line['quantity_c_size_'.$con_size[$x].'_chain']?>, <? $category = $line['style1']; switch ($category) { case "ankle-boots": echo "10013"; break; case "knee-high-boots": echo "10011"; break; case "high-heel-boots": echo "10033"; break; case "low-heel-boots": echo "10014"; break; case "wedge-boots": echo "10014"; break; case "western-boots": echo "10032"; break; case "flat-shoes": echo "10034"; break; case "high-heel-shoes": echo "10039"; break; case "low-heel-shoes": echo "10039"; break; case "wedge-shoes": echo "10035"; break; case "ballerina-shoes": echo "10008"; break; case "boat-shoes": echo "10018"; break; case "loafer-shoes": echo "10037"; break; case "work-shoes": echo "10039"; break; case "flat-sandals": echo "10041"; break; case "low-heel-sandals": echo "10042"; break; case "high-heel-sandals": echo "10042"; break; case "wedge-sandals": echo "10042"; break; case "mule-sandals": echo "10038"; break; case "mary-jane-shoes": echo "10039"; break; case "sports-shoes": echo "10026"; break; case "court-shoes": echo "10035"; break; case "peep-toe-shoes": echo "10035"; break; case "flat-boots": echo "10609"; break; case "mid-calf-boots": echo "10014"; break; case "trainer-shoes": echo "10009"; break; case "wellington-boots": echo "10012"; break; case "lace-up-boots": echo "10609"; break; case "chelsea-and-jodphur-boots": echo "10609"; break; case "desert-and-chukka-boots": echo "10032"; break; case "lace-up-shoes": echo "10034"; break; case "slip-on-shoes": echo "10043"; break; case "gibson-and-derby-shoes": echo "10039"; break; case "oxford-shoes": echo "10039"; break; case "brogue-shoes": echo "10039"; break; case "winter-boots": echo "10021"; break; case "slipper-shoes": echo "10016"; break; case "mid-heel-shoes": echo "10039"; break; case "sandals-and-beach-shoes": echo "10044"; break; case "mid-heel-sandals": echo "10042"; break; case "mid-heel-boots": echo "10014"; break; default: echo ""; } ?>, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_1.jpg, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_2.jpg, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_3.jpg, http://www.getashoe.co.uk/full/<?=$line['product_id']?>_4.jpg, , , , , <? $colour = preg_replace('/[^\da-z]/i', ' ', $line['colour']); if( preg_match( '/white.*/i', $colour)) { echo '1'; } elseif( preg_match( '/yellow.*/i', $colour)) { echo '4'; } elseif( preg_match( '/orange.*/i', $colour)) { echo '7'; } elseif( preg_match( '/red.*/i', $colour)) { echo '8'; } elseif( preg_match( '/pink.*/i', $colour)) { echo '13'; } elseif( preg_match( '/purple.*/i', $colour)) { echo '15'; } elseif( preg_match( '/blue.*/i', $colour)) { echo '19'; } elseif( preg_match( '/green.*/i', $colour)) { echo '25'; } elseif( preg_match( '/brown.*/i', $colour)) { echo '28'; } elseif( preg_match( '/grey.*/i', $colour)) { echo '35'; } elseif( preg_match( '/black.*/i', $colour)) { echo '38'; } elseif( preg_match( '/gold.*/i', $colour)) { echo '41'; } elseif( preg_match( '/silver.*/i', $colour)) { echo '46'; } elseif( preg_match( '/multi.*/i', $colour)) { echo '594'; } elseif( preg_match( '/beige.*/i', $colour)) { echo '6887'; } elseif( preg_match( '/nude.*/i', $colour)) { echo '6887'; } else { echo '534'; } ?>, <?=$line['colour']?>, <?=$con_size[$x]?> <br> <? // finish checking if size is available } } ?> So at the moment this is simply echoing out the product_ID into the SKU column. The code would need to enter the product_id into an array and check whether it is unique. If the product_id is unique to the array, then the product_id is echoed out unaltered, and parent is echoed out to the 'Parent/Child' column and then the product_id is repeated to the 'Parent SKU' column. However, if the array is checked and the product_id already exists in the array, then the product_id is echoed out to the 'SKU' column with a suffix i.e. _1. Then child is echoed to the 'Parent / Child' column and the original parent product_id echoed to the 'Parent SKU' column. HOWEVER - the same SKU cannot be repeated with the same suffix i.e. 12345_1, 12345_1 - so presumably there would be to be another array for the suffixed SKUs to be checked against. If anybody could help, it would be great. Thanks --- UPDATE ANSWER --- I managed to solved this myself and thought I would share my solution for future reference. /* * Array to collect product_ids and check whether unique. * If unique product_id becomes parent SKU * If not product_id becomes child of previous parent and suffixed with _1, _2 etc... */ if (!in_array($line['product_id'], $SKU)) { $SKU[] = $line['product_id']; $parent = $line['product_id']; $a = 0; ?> <? echo 'Shoes'; ?>, <? echo $parent; ?>, <? echo "Parent"; ?>, <? echo $parent; ?>, <? } else { $child = $line['product_id'] . "_" . $a; ?> <? echo 'Shoes'; ?>, <? echo $child; ?>, <? echo "Child"; ?>, <? echo $child; <? // increment suffix value for child SKU $a++; ?>

  • STORED PROCEDURE working in my local test machine cannot be created in production environment.

    - by Marcos Buarque
    Hi, I have an SQL CREATE PROCEDURE statement that runs perfectly in my local SQL Server, but cannot be recreated in production environment. The error message I get in production is Msg 102, Level 15, State 1, Incorrect syntax near '='. It is a pretty big query and I don't want to annoy StackOverflow users, but I simply can't find a solution. If only you could point me out what settings I could check in the production server in order to enable running the code... I must be using some kind of syntax or something that is conflicting with some setting in production. This PROCEDURE was already registered in production before, but when I ran a DROP - CREATE PROCEDURE today, the server was able to drop the procedure, but not to recreate it.

  • Losing NSManaged Objects in my Application

    - by Wayfarer
    I've been doing quite a bit of work on a fun little iPhone app. At one point, I get a bunch of player objects from my Persistant store, and then display them on the screen. I also have the options of adding new player objects (their just custom UIButtons) and removing selected players. However, I believe I'm running into some memory management issues, in that somehow the app is not saving which "players" are being displayed. Example: I have 4 players shown, I select them all and then delete them all. They all disappear. But if I exit and then reopen the application, they all are there again. As though they had never left. So somewhere in my code, they are not "really" getting removed. MagicApp201AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; context = [appDelegate managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *desc = [NSEntityDescription entityForName:@"Player" inManagedObjectContext:context]; [request setEntity:desc]; NSError *error; NSMutableArray *objects = [[[context executeFetchRequest:request error:&error] mutableCopy] autorelease]; if (objects == nil) { NSLog(@"Shit man, there was an error taking out the single player object when the view did load. ", error); } int j = 0; while (j < [objects count]) { if ([[[objects objectAtIndex:j] valueForKey:@"currentMultiPlayer"] boolValue] == NO) { [objects removeObjectAtIndex:j]; j--; } else { j++; } } [self setPlayers:objects]; //This is a must, it NEEDS to work Objects are all the players playing So in this snippit (in the viewdidLoad method), I grab the players out of the persistant store, and then remove the objects I don't want (those whose boolValue is NO), and the rest are kept. This works, I'm pretty sure. I think the issue is where I remove the players. Here is that code: NSLog(@"Remove players"); /** For each selected player: Unselect them (remove them from SelectedPlayers) Remove the button from the view Remove the button object from the array Remove the player from Players */ NSLog(@"Debugging Removal: %d", [selectedPlayers count]); for (int i=0; i < [selectedPlayers count]; i++) { NSManagedObject *rPlayer = [selectedPlayers objectAtIndex:i]; [rPlayer setValue:[NSNumber numberWithBool:NO] forKey:@"currentMultiPlayer"]; int index = [players indexOfObjectIdenticalTo:rPlayer]; //this is the index we need for (int j = (index + 1); j < [players count]; j++) { UIButton *tempButton = [playerButtons objectAtIndex:j]; tempButton.tag--; } NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } UIButton *aButton = [playerButtons objectAtIndex:index]; [players removeObjectAtIndex:index]; [aButton removeFromSuperview]; [playerButtons removeObjectAtIndex:index]; } [selectedPlayers removeAllObjects]; NSError *error; if ([context hasChanges] && ![context save:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } NSLog(@"About to refresh YES"); [self refreshAllPlayers:YES]; The big part in the second code snippet is I set them to NO for currentMultiPlayer. NO NO NO NO NO, they should NOT come back when the view does load, NEVER ever ever. Not until I say so. No other relevant part of the code sets that to YES. Which makes me think... perhaps they aren't being saved. Perhaps that doesn't save, perhaps those objects aren't being managed anymore, and so they don't get saved in. Is there a lifetime (metaphorically) of NSManaged object? The Players array is the same I set in the "viewDidLoad" method, and SelectedPlayers holds players that are selected, references to NSManagedObjects. Does it have something to do with Removing them from the array? I'm so confused, some insight would be greatly appreciated!!

  • App crashes when adding array data to table cells

    - by bassmandan
    I am trying to create a table view that loads a number of tweets into the table (one per cell etc). I am using NSXMLParser to get the information and have got as far as creating an array with the selection of tweets that I want. However, when I try to add them to the table cells, the app crashes on the line: cell.textLabel.text = cellValue; An NSLog before this shows in the console that the app is getting the correct data, so I am a bit stumped as to why this isn't working. This is the block of code that appears to be having the problem: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } // Set up the cell... NSString *cellValue = [statuses objectAtIndex:indexPath.row]; NSLog(@"%@", cellValue); cell.textLabel.text = cellValue; return cell;} If it makes a difference, I am using ARC and the latest version of XCode. I'm still quite new to all this, so if I need to give some extra information, let me know. Thanks in advance.

  • c++ and c# speed compared

    - by Mack
    I was worried about C#'s speed when it deals with heavy calculations, when you need to use raw CPU power. I always thought that C++ is much faster than C# when it comes to calculations. So I did some quick tests. The first test computes prime numbers < an integer n, the second test computes some pandigital numbers. The idea for second test comes from here: Pandigital Numbers C# prime computation: using System; using System.Diagnostics; class Program { static int primes(int n) { uint i, j; int countprimes = 0; for (i = 1; i <= n; i++) { bool isprime = true; for (j = 2; j <= Math.Sqrt(i); j++) if ((i % j) == 0) { isprime = false; break; } if (isprime) countprimes++; } return countprimes; } static void Main(string[] args) { int n = int.Parse(Console.ReadLine()); Stopwatch sw = new Stopwatch(); sw.Start(); int res = primes(n); sw.Stop(); Console.WriteLine("I found {0} prime numbers between 0 and {1} in {2} msecs.", res, n, sw.ElapsedMilliseconds); Console.ReadKey(); } } C++ variant: #include <iostream> #include <ctime> int primes(unsigned long n) { unsigned long i, j; int countprimes = 0; for(i = 1; i <= n; i++) { int isprime = 1; for(j = 2; j < (i^(1/2)); j++) if(!(i%j)) { isprime = 0; break; } countprimes+= isprime; } return countprimes; } int main() { int n, res; cin>>n; unsigned int start = clock(); res = primes(n); int tprime = clock() - start; cout<<"\nI found "<<res<<" prime numbers between 1 and "<<n<<" in "<<tprime<<" msecs."; return 0; } When I ran the test trying to find primes < than 100,000, C# variant finished in 0.409 seconds and C++ variant in 5.553 seconds. When I ran them for 1,000,000 C# finished in 6.039 seconds and C++ in about 337 seconds. Pandigital test in C#: using System; using System.Diagnostics; class Program { static bool IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return false; } return digits == (1 << count) - 1; } static void Main() { int pans = 0; Stopwatch sw = new Stopwatch(); sw.Start(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } sw.Stop(); Console.WriteLine("{0}pcs, {1}ms", pans, sw.ElapsedMilliseconds); Console.ReadKey(); } } Pandigital test in C++: #include <iostream> #include <ctime> using namespace std; int IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return 0; } return digits == (1 << count) - 1; } int main() { int pans = 0; unsigned int start = clock(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } int ptime = clock() - start; cout<<"\nPans:"<<pans<<" time:"<<ptime; return 0; } C# variant runs in 29.906 seconds and C++ in about 36.298 seconds. I didn't touch any compiler switches and bot C# and C++ programs were compiled with debug options. Before I attempted to run the test I was worried that C# will lag well behind C++, but now it seems that there is a pretty big speed difference in C# favor. Can anybody explain this? C# is jitted and C++ is compiled native so it's normal that a C++ will be faster than a C# variant. Thanks for the answers!

  • Need some suggestions on my softwares architecture. [Code review]

    - by Sergio Tapia
    I'm making an open source C# library for other developers to use. My key concern is ease of use. This means using intuitive names, intuitive method usage and such. This is the first time I've done something with other people in mind, so I'm really concerned about the quality of the architecture. Plus, I wouldn't mind learning a thing or two. :) I have three classes: Downloader, Parser and Movie I was thinking that it would be best to only expose the Movie class of my library and have Downloader and Parser remain hidden from invocation. Ultimately, I see my library being used like this. using FreeIMDB; public void Test() { var MyMovie = Movie.FindMovie("The Matrix"); //Now MyMovie would have all it's fields set and ready for the big show. } Can you review how I'm planning this, and point out any wrong judgement calls I've made and where I could improve. Remember, my main concern is ease of use. Movie.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Drawing; namespace FreeIMDB { public class Movie { public Image Poster { get; set; } public string Title { get; set; } public DateTime ReleaseDate { get; set; } public string Rating { get; set; } public string Director { get; set; } public List<string> Writers { get; set; } public List<string> Genres { get; set; } public string Tagline { get; set; } public string Plot { get; set; } public List<string> Cast { get; set; } public string Runtime { get; set; } public string Country { get; set; } public string Language { get; set; } public Movie FindMovie(string Title) { Movie film = new Movie(); Parser parser = Parser.FromMovieTitle(Title); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } public Movie FindKnownMovie(string ID) { Movie film = new Movie(); Parser parser = Parser.FromMovieID(ID); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } } } Parser.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using HtmlAgilityPack; namespace FreeIMDB { /// <summary> /// Provides a simple, and intuitive way for searching for movies and actors on IMDB. /// </summary> class Parser { private Downloader downloader = new Downloader(); private HtmlDocument Page; #region "Page Loader Events" private Parser() { } public static Parser FromMovieTitle(string MovieTitle) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindMovie(MovieTitle); return newParser; } public static Parser FromActorName(string ActorName) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindActor(ActorName); return newParser; } public static Parser FromMovieID(string MovieID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownMovie(MovieID); return newParser; } public static Parser FromActorID(string ActorID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownActor(ActorID); return newParser; } #endregion #region "Page Parsing Methods" public string Poster() { //Logic to scrape the Poster URL from the Page element of this. return null; } public string Title() { return null; } public DateTime ReleaseDate() { return null; } #endregion } } ----------------------------------------------- Do you guys think I'm heading towards a good path, or am I setting myself up for a world of hurt later on? My original thought was to separate the downloading, the parsing and the actual populating to easily have an extensible library. Imagine if one day the website changed its HTML, I would then only have to modifiy the parsing class without touching the Downloader.cs or Movie.cs class. Thanks for reading and for helping!

  • Cnoverting application to MVC architecture

    I'm practicing writing MVC applications. I have a Mastermind game, that I would like to rewrite as MVC app. I have divided my code to parts, but instead of working game I'm getting empty Frame and an error in "public void paint( Graphics g )".

  • Table overflow working in Chrome and IE but not Firefox

    - by Craig
    I am trying to get a layout that always takes up the entire screen, no more, no less. The layout has a header row, a 200px wide left bar (scrollable), and a scrollable content area. This works in Chrome and IE, but in Firefox the scroll bars never show nor work. Any thoughts? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"> <html> <head> <style type="text/css"> * { margin: 0; padding: 0; } html, body { height: 100%; background-color: yellow; overflow: hidden; } #viewTable { width: 100%; height: 100%; background-color: red; } #header { height: 72px; background-color: blue; } #leftcol { vertical-align: top; width: 200px; height: 100%; background-color: green; } #menu { height: 100%; overflow: auto; } #rightcol { vertical-align: top; width: auto; height: 100%; background-color: purple; } #content { height: 100%; overflow: auto; } </style> </head> <body> </body> <table id="viewTable" border="0" cellpadding="0" cellspacing="0"> <tr> <td colspan="2" id="header"> Header </td> </tr> <tr> <td id="leftcol"> <div id="menu"> 0<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 100<br/> </div> </td> <td id="rightcol"> <div id="content"> 0<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 1<br/> 100<br/> </div> </td> </tr> </table> hi </html> I would have preferred to use CSS, but could not find any way to do it.

  • Simple Physics Simulation in java not working.

    - by Static Void Main
    Dear experts, I wanted to implement ball physics and as i m newbie, i adapt the code in tutorial http://adam21.web.officelive.com/Documents/JavaPhysicsTutorial.pdf . i try to follow that as i much as i can, but i m not able to apply all physical phenomenon in code, can somebody please tell me, where i m mistaken or i m still doing some silly programming mistake. The balls are moving when i m not calling bounce method and i m unable to avail the bounce method and ball are moving towards left side instead of falling/ending on floor**, Can some body recommend me some better way or similar easy compact way to accomplish this task of applying physics on two ball or more balls with interactivity. here is code ; import java.awt.*; public class AdobeBall { protected int radius = 20; protected Color color; // ...

  • directX texture appears incorrectly

    - by numerical25
    I finally managed to get a texture onto a cube sadly, but it is appearing incorrectly. as the below picture identifies. Anyways, I am not sure what it could be. My first guess is it could be my uv mapping or my vertex positioning is off. If someone could check and make sure thats good. The first element is the vertex position, second is the color, and third is the uv texture. //Create vectors and put in vertices // Create vertex buffer VertexPos vertices[] = { // BACK SIDES { D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, // 2 FRONT SIDE { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f) , D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.0f,0.0f), D3DXVECTOR2(1.0,1.0)}, // 3 { D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,2.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, // 4 { D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(1.0f,0.5f,0.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, // 5 { D3DXVECTOR3(5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,0.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,1.0)}, { D3DXVECTOR3(5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(1.0,0.0)}, { D3DXVECTOR3(5.0f, -5.0f, 5.0f), D3DXVECTOR4(0.0f,1.0f,0.5f,0.0f), D3DXVECTOR2(0.0,2.0)}, // 6 {D3DXVECTOR3(-5.0f, 5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,0.0)}, {D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, {D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, {D3DXVECTOR3(-5.0f, 5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, {D3DXVECTOR3(-5.0f, -5.0f, -5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(1.0,0.0)}, {D3DXVECTOR3(-5.0f, -5.0f, 5.0f), D3DXVECTOR4(0.5f,0.0f,1.0f,0.0f), D3DXVECTOR2(0.0,1.0)}, }; My second guess could be an error that I am receiving as I run the program.

  • SQL: Using a CASE Statement to update 1000 rows at once

    - by SoLoGHoST
    Ok, I would like to use a CASE STATEMENT for this, but I am lost with this. Basically, I need to update a ton of rows, but just on the "position" column. I need to update all "position" values from 0 - count(position) for each id_layout_position column per id_layout column. OK, here is a pic of what the table looks like: Now let's say I delete the circled row, this will remove position = 2 and give me: 0, 1, 3, 5, 6, 7, and 4. But I want to add something at the end now and make sure that it has the last possible position, but the positions are already messed up, so I need to reorder them like so before I insert the new row: 0, 1, 2, 3, 4, 5, 6. But it must be ordered by lowest first. So 0 stays at 0, 1 stays at 1, 3 gets changed to 2, the 4 at the end gets changed to a 3, 5 gets changed to 4, 6 gets changed to 5, and 7 gets changed to 6. Hopefully you guys get the picture now. I'm completely lost here. Also, note, this table is tiny compared to how fast it can grow in size, so it needs to be able to do this FAST, thus I was thinking on the CASE STATEMENT for an UPDATE QUERY. Here's what I got for a regular update, but I don't wanna throw this into a foreach loop, as it would take forever to do it. I'm using SMF (Simple Machines Forums), so it might look a little different, but the idea is the same, and CASE statements are supported... $smcFunc['db_query']('', ' UPDATE {db_prefix}dp_positions SET position = {int:position} WHERE id_layout_position = {int:id_layout_position} AND id_layout = {int:id_layout}', array( 'position' => $position++, 'id_layout_position' => (int) $id_layout_position, 'id_layout' => (int) $id_layout, ) ); Anyways, I need to apply some sort of CASE on this so that I can auto-increment by 1 all values that it finds and update to the next possible value. I know I'm doing this wrong, even in this QUERY. But I'm totally lost when it comes to CASES. Here's an example of a CASE being used within SMF, so you can see this and hopefully relate: $conditions = ''; foreach ($postgroups as $id => $min_posts) { $conditions .= ' WHEN posts >= ' . $min_posts . (!empty($lastMin) ? ' AND posts <= ' . $lastMin : '') . ' THEN ' . $id; $lastMin = $min_posts; } // A big fat CASE WHEN... END is faster than a zillion UPDATE's ;). $smcFunc['db_query']('', ' UPDATE {db_prefix}members SET id_post_group = CASE ' . $conditions . ' ELSE 0 END' . ($parameter1 != null ? ' WHERE ' . (is_array($parameter1) ? 'id_member IN ({array_int:members})' : 'id_member = {int:members}') : ''), array( 'members' => $parameter1, ) ); Before I do the update, I actually have a SELECT which throws everything I need into arrays like so: $disabled_sections = array(); $positions = array(); while ($row = $smcFunc['db_fetch_assoc']($request)) { if (!isset($disabled_sections[$row['id_group']][$row['id_layout']])) $disabled_sections[$row['id_group']][$row['id_layout']] = array( 'info' => $module_info[$name], 'id_layout_position' => $row['id_layout_position'] ); // Increment the positions... if (!is_null($row['position'])) { if (!isset($positions[$row['id_layout']][$row['id_layout_position']])) $positions[$row['id_layout']][$row['id_layout_position']] = 1; else $positions[$row['id_layout']][$row['id_layout_position']]++; } else $positions[$row['id_layout']][$row['id_layout_position']] = 0; } Thanks, I know if anyone can help me here it's definitely you guys and gals... Anyways, here is my question: How do I use a CASE statement in the first code example, so that I can update all of the rows in the position column from 0 - total # of rows found, that have that id_layout value and that id_layout_position value, and continue this for all different id_layout values in that table? Can I use the arrays above somehow? I'm sure I'll have to use the id_layout and id_layout_position values for this right? But how can I do this? Ok, guy, I get an error, saying "Hacking Attempt" with the following code: // Updating all positions in here. $smcFunc['db_query']('', ' SET @pos = 0; UPDATE {db_prefix}dp_positions SET position=@pos:=@pos+1 ORDER BY id_layout_position, position', array( ) ); Am I doing something wrong? Perhaps SMF has safeguards against this approach?? Perhaps I need to use a CASE STATEMENT instead?

  • Allowing pop-up's and downloads with flex

    - by ShadowVariable
    I'm building an flex app that is basically a wrapper for a few websites. One of them is a google docs website, and I'm trying to get flex to allow downloads or popups or something that will allow me to do it.

  • MEF + Plug-In not updating

    - by mybrokengnome
    I asked this on the MEF Codeplex forum already, but I haven't gotten a response yet, so I figured I'd try StackOverflow. Here's the original post if anyone's interested (this is just a copy from it): MEF Codeplex "Let me first say that I'm completely new to MEF (just discovered it today) and am very happy with it so far. However, I've ran in to a problem that is very frustrating. I'm creating an app that will have a plugin architecture and the plugins will only be stored in a single DLL file (or coded into the main app). The DLL file needs to be able to be recompiled during run-time and the app should recognize this and re-load the plugins (I know this is difficult, but it's a requirement). To accomplish this I took the approach covered http://blog.maartenballiauw.be/category/MEF.aspx there (look for WebServerDirectoryCatalog). Basically the idea is to "monitor the plugins folder, copy the new/modified assemblies to the web application’s /bin folder and instruct MEF to load its exports from there." This is my code, which is probably not the correct way to do it but it's what I found in some samples around the net: main()... string myExecName = Assembly.GetExecutingAssembly().Location; string myPath = System.IO.Path.GetDirectoryName(myExecName); catalog = new AggregateCatalog(); pluginCatalog = new MyDirectoryCatalog(myPath + @"/Plugins"); catalog.Catalogs.Add(pluginCatalog); exportContainer = new CompositionContainer(catalog); CompositionBatch compBatch = new CompositionBatch(); compBatch.AddPart(this); compBatch.AddPart(catalog); exportContainer.Compose(compBatch); and private FileSystemWatcher fileSystemWatcher; public DirectoryCatalog directoryCatalog; private string path; private string extension; public MyDirectoryCatalog(string path) { Initialize(path, "*.dll", "*.dll"); } private void Initialize(string path, string extension, string modulePattern) { this.path = path; this.extension = extension; fileSystemWatcher = new FileSystemWatcher(path, modulePattern); fileSystemWatcher.Changed += new FileSystemEventHandler(fileSystemWatcher_Changed); fileSystemWatcher.Created += new FileSystemEventHandler(fileSystemWatcher_Created); fileSystemWatcher.Deleted += new FileSystemEventHandler(fileSystemWatcher_Deleted); fileSystemWatcher.Renamed += new RenamedEventHandler(fileSystemWatcher_Renamed); fileSystemWatcher.IncludeSubdirectories = false; fileSystemWatcher.EnableRaisingEvents = true; Refresh(); } void fileSystemWatcher_Renamed(object sender, RenamedEventArgs e) { RemoveFromBin(e.OldName); Refresh(); } void fileSystemWatcher_Deleted(object sender, FileSystemEventArgs e) { RemoveFromBin(e.Name); Refresh(); } void fileSystemWatcher_Created(object sender, FileSystemEventArgs e) { Refresh(); } void fileSystemWatcher_Changed(object sender, FileSystemEventArgs e) { Refresh(); } private void Refresh() { // Determine /bin path string binPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Plugins"); string newPath = ""; // Copy files to /bin foreach (string file in Directory.GetFiles(path, extension, SearchOption.TopDirectoryOnly)) { try { DirectoryInfo dInfo = new DirectoryInfo(binPath); DirectoryInfo[] dirs = dInfo.GetDirectories(); int count = dirs.Count() + 1; newPath = binPath + "/" + count; DirectoryInfo dInfo2 = new DirectoryInfo(newPath); if (!dInfo2.Exists) dInfo2.Create(); File.Copy(file, System.IO.Path.Combine(newPath, System.IO.Path.GetFileName(file)), true); } catch { // Not that big deal... Blog readers will probably kill me for this bit of code :-) } } // Create new directory catalog directoryCatalog = new DirectoryCatalog(newPath, extension); directoryCatalog.Refresh(); } public override IQueryable<ComposablePartDefinition> Parts { get { return directoryCatalog.Parts; } } private void RemoveFromBin(string name) { string binPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, ""); File.Delete(Path.Combine(binPath, name)); } So all this actually works, and after the end of the code in main my IEnumerable variable is actually filled with all the plugins in the DLL (which if you follow the code is located in Plugins/1 so that I can modify the dll in the plugins folder). So now at this point I should be able to re-compile the plugins DLL, drop it in to the Plugins folder, my FileWatcher detect that it's changed, and then copy it into folder "2" and directoryCatalog should point to the new folder. All this actually works! The problem is, even though it seems like every thing is pointed to the right place, my IEnumerable variable is never updated with the new plugins. So close, but yet so far! Any suggestions? I know the downsides of doing it this way, that no dll is actually getting unloaded and causing a memory leak, but it's a Windows App and will probably be started at least once a day, and the plugins are un-likely to change that often, but it's still a requirement from the client that it does this without re-loading the app. Thanks! Thanks for any help you all can provide, it's driving me crazy not being able to figure this out."

  • Min-Ordered Bionomial Heap Insertion java

    - by Charodd Richardson
    Im writing a java code to make a min-ordered Binomial Heap and I have to Insert and Remove-min. I'm having a very big problem inserting into the Heap. I have been stuck on this for a couple of days now and it is due tomorrow. Whenever I go to insert, It only prints out the item I insert instead of the whole tree (which is in preorder). Such as if I insert 1 it prints (1) and then I go to insert 2 it prints out (2) instead of (1(2)) It keeps printing out only the number I insert last instead of the whole preordered tree. I would be very grateful if someone could help me with this problem. Thank you so much in advance, Here is my code. public class BHeap { int key; int degree;//The degree(Number of children) BHeap parent, leftmostChild, rightmostChild, rightSibling,root,previous,next; public BHeap(){ key =0; degree=0; parent =null; leftmostChild=null; rightmostChild=null; rightSibling=null; root=null; previous=null; next=null; } public BHeap merge(BHeap x, BHeap y){ BHeap newHeap = new BHeap(); y.rightSibling=x.root; BHeap currentHeap = y; BHeap nextHeap = y.rightSibling; while(currentHeap.rightSibling !=null){ if(currentHeap.degree==nextHeap.degree){ if(currentHeap.key<nextHeap.key){ if(currentHeap.degree ==0){ currentHeap.leftmostChild=nextHeap; currentHeap.rightmostChild=nextHeap; currentHeap.rightSibling=nextHeap.rightSibling; nextHeap.rightSibling=null; nextHeap.parent=currentHeap; currentHeap.degree++; } else{ newHeap = currentHeap; newHeap.rightmostChild.rightSibling=nextHeap; newHeap.rightmostChild=nextHeap; nextHeap.parent=newHeap; newHeap.degree++; nextHeap.rightSibling=null; nextHeap=newHeap.rightSibling; } } else{ if(currentHeap.degree==0){ nextHeap.rightmostChild=currentHeap; nextHeap.rightmostChild.root = nextHeap.rightmostChild;//add nextHeap.leftmostChild=currentHeap; nextHeap.leftmostChild.root = nextHeap.leftmostChild;//add currentHeap.parent=nextHeap; currentHeap.rightSibling=null; currentHeap.root=currentHeap;//add nextHeap.degree++; } else{ newHeap=nextHeap; newHeap.rightmostChild.rightSibling=currentHeap; newHeap.rightmostChild=currentHeap; currentHeap.parent= newHeap; newHeap.degree++; currentHeap=newHeap.rightSibling; currentHeap.rightSibling=null; } } } else{ currentHeap=currentHeap.rightSibling; nextHeap=nextHeap.rightSibling; } } return y; } public void Insert(int x){ /*BHeap newHeap = new BHeap(); newHeap.key=x; if(this.root==null){ this.root=newHeap; return; } else{ this.root=merge(newHeap,this.root); }*/ BHeap newHeap= new BHeap(); newHeap.key=x; if(this.root==null){ this.root=newHeap; } else{ this.root = merge(this,newHeap); }} public void RemoveMin(){ BHeap newHeap = new BHeap(); BHeap child = new BHeap(); newHeap=this; BHeap pos = newHeap.next; while(pos !=null){ if(pos.key<newHeap.key){ newHeap=pos; } pos=pos.rightSibling; } pos=this; BHeap B1 = new BHeap(); if(newHeap.previous!=null){ newHeap.previous.rightSibling=newHeap.rightSibling; B1 =pos.leftmostChild; B1.rightSibling=pos; pos.leftmostChild=pos.rightmostChild.leftmostChild; } else{ newHeap=newHeap.rightSibling; newHeap.previous.rightSibling=newHeap.rightSibling; B1 =pos.leftmostChild; B1.rightSibling=pos; pos.leftmostChild=pos.rightmostChild.leftmostChild; } merge(newHeap,B1); } public void Display(){ System.out.print("("); System.out.print(this.root.key); if(this.leftmostChild != null){ this.leftmostChild.Display(); } System.out.print(")"); if(this.rightSibling!=null){ this.rightSibling.Display(); } } }

  • Microsoft and jQuery

    - by Rick Strahl
    The jQuery JavaScript library has been steadily getting more popular and with recent developments from Microsoft, jQuery is also getting ever more exposure on the ASP.NET platform including now directly from Microsoft. jQuery is a light weight, open source DOM manipulation library for JavaScript that has changed how many developers think about JavaScript. You can download it and find more information on jQuery on www.jquery.com. For me jQuery has had a huge impact on how I develop Web applications and was probably the main reason I went from dreading to do JavaScript development to actually looking forward to implementing client side JavaScript functionality. It has also had a profound impact on my JavaScript skill level for me by seeing how the library accomplishes things (and often reviewing the terse but excellent source code). jQuery made an uncomfortable development platform (JavaScript + DOM) a joy to work on. Although jQuery is by no means the only JavaScript library out there, its ease of use, small size, huge community of plug-ins and pure usefulness has made it easily the most popular JavaScript library available today. As a long time jQuery user, I’ve been excited to see the developments from Microsoft that are bringing jQuery to more ASP.NET developers and providing more integration with jQuery for ASP.NET’s core features rather than relying on the ASP.NET AJAX library. Microsoft and jQuery – making Friends jQuery is an open source project but in the last couple of years Microsoft has really thrown its weight behind supporting this open source library as a supported component on the Microsoft platform. When I say supported I literally mean supported: Microsoft now offers actual tech support for jQuery as part of their Product Support Services (PSS) as jQuery integration has become part of several of the ASP.NET toolkits and ships in several of the default Web project templates in Visual Studio 2010. The ASP.NET MVC 3 framework (still in Beta) also uses jQuery for a variety of client side support features including client side validation and we can look forward toward more integration of client side functionality via jQuery in both MVC and WebForms in the future. In other words jQuery is becoming an optional but included component of the ASP.NET platform. PSS support means that support staff will answer jQuery related support questions as part of any support incidents related to ASP.NET which provides some piece of mind to some corporate development shops that require end to end support from Microsoft. In addition to including jQuery and supporting it, Microsoft has also been getting involved in providing development resources for extending jQuery’s functionality via plug-ins. Microsoft’s last version of the Microsoft Ajax Library – which is the successor to the native ASP.NET AJAX Library – included some really cool functionality for client templates, databinding and localization. As it turns out Microsoft has rebuilt most of that functionality using jQuery as the base API and provided jQuery plug-ins of these components. Very recently these three plug-ins were submitted and have been approved for inclusion in the official jQuery plug-in repository and been taken over by the jQuery team for further improvements and maintenance. Even more surprising: The jQuery-templates component has actually been approved for inclusion in the next major update of the jQuery core in jQuery V1.5, which means it will become a native feature that doesn’t require additional script files to be loaded. Imagine this – an open source contribution from Microsoft that has been accepted into a major open source project for a core feature improvement. Microsoft has come a long way indeed! What the Microsoft Involvement with jQuery means to you For Microsoft jQuery support is a strategic decision that affects their direction in client side development, but nothing stopped you from using jQuery in your applications prior to Microsoft’s official backing and in fact a large chunk of developers did so readily prior to Microsoft’s announcement. Official support from Microsoft brings a few benefits to developers however. jQuery support in Visual Studio 2010 means built-in support for jQuery IntelliSense, automatically added jQuery scripts in many projects types and a common base for client side functionality that actually uses what most developers are already using. If you have already been using jQuery and were worried about straying from the Microsoft line and their internal Microsoft Ajax Library – worry no more. With official support and the change in direction towards jQuery Microsoft is now following along what most in the ASP.NET community had already been doing by using jQuery, which is likely the reason for Microsoft’s shift in direction in the first place. ASP.NET AJAX and the Microsoft AJAX Library weren’t bad technology – there was tons of useful functionality buried in these libraries. However, these libraries never got off the ground, mainly because early incarnations were squarely aimed at control/component developers rather than application developers. For all the functionality that these controls provided for control developers they lacked in useful and easily usable application developer functionality that was easily accessible in day to day client side development. The result was that even though Microsoft shipped support for these tools in the box (in .NET 3.5 and 4.0), other than for the internal support in ASP.NET for things like the UpdatePanel and the ASP.NET AJAX Control Toolkit as well as some third party vendors, the Microsoft client libraries were largely ignored by the developer community opening the door for other client side solutions. Microsoft seems to be acknowledging developer choice in this case: Many more developers were going down the jQuery path rather than using the Microsoft built libraries and there seems to be little sense in continuing development of a technology that largely goes unused by the majority of developers. Kudos for Microsoft for recognizing this and gracefully changing directions. Note that even though there will be no further development in the Microsoft client libraries they will continue to be supported so if you’re using them in your applications there’s no reason to start running for the exit in a panic and start re-writing everything with jQuery. Although that might be a reasonable choice in some cases, jQuery and the Microsoft libraries work well side by side so that you can leave existing solutions untouched even as you enhance them with jQuery. The Microsoft jQuery Plug-ins – Solid Core Features One of the most interesting developments in Microsoft’s embracing of jQuery is that Microsoft has started contributing to jQuery via standard mechanism set for jQuery developers: By submitting plug-ins. Microsoft took some of the nicest new features of the unpublished Microsoft Ajax Client Library and re-wrote these components for jQuery and then submitted them as plug-ins to the jQuery plug-in repository. Accepted plug-ins get taken over by the jQuery team and that’s exactly what happened with the three plug-ins submitted by Microsoft with the templating plug-in even getting slated to be published as part of the jQuery core in the next major release (1.5). The following plug-ins are provided by Microsoft: jQuery Templates – a client side template rendering engine jQuery Data Link – a client side databinder that can synchronize changes without code jQuery Globalization – provides formatting and conversion features for dates and numbers The first two are ports of functionality that was slated for the Microsoft Ajax Library while functionality for the globalization library provides functionality that was already found in the original ASP.NET AJAX library. To me all three plug-ins address a pressing need in client side applications and provide functionality I’ve previously used in other incarnations, but with more complete implementations. Let’s take a close look at these plug-ins. jQuery Templates http://api.jquery.com/category/plugins/templates/ Client side templating is a key component for building rich JavaScript applications in the browser. Templating on the client lets you avoid from manually creating markup by creating DOM nodes and injecting them individually into the document via code. Rather you can create markup templates – similar to the way you create classic ASP server markup – and merge data into these templates to render HTML which you can then inject into the document or replace existing content with. Output from templates are rendered as a jQuery matched set and can then be easily inserted into the document as needed. Templating is key to minimize client side code and reduce repeated code for rendering logic. Instead a single template can be used in many places for updating and adding content to existing pages. Further if you build pure AJAX interfaces that rely entirely on client rendering of the initial page content, templates allow you to a use a single markup template to handle all rendering of each specific HTML section/element. I’ve used a number of different client rendering template engines with jQuery in the past including jTemplates (a PHP style templating engine) and a modified version of John Resig’s MicroTemplating engine which I built into my own set of libraries because it’s such a commonly used feature in my client side applications. jQuery templates adds a much richer templating model that allows for sub-templates and access to the data items. Like John Resig’s original Micro Template engine, the core basics of the templating engine create JavaScript code which means that templates can include JavaScript code. To give you a basic idea of how templates work imagine I have an application that downloads a set of stock quotes based on a symbol list then displays them in the document. To do this you can create an ‘item’ template that describes how each of the quotes is renderd as a template inside of the document: <script id="stockTemplate" type="text/x-jquery-tmpl"> <div id="divStockQuote" class="errordisplay" style="width: 500px;"> <div class="label">Company:</div><div><b>${Company}(${Symbol})</b></div> <div class="label">Last Price:</div><div>${LastPrice}</div> <div class="label">Net Change:</div><div> {{if NetChange > 0}} <b style="color:green" >${NetChange}</b> {{else}} <b style="color:red" >${NetChange}</b> {{/if}} </div> <div class="label">Last Update:</div><div>${LastQuoteTimeString}</div> </div> </script> The ‘template’ is little more than HTML with some markup expressions inside of it that define the template language. Notice the embedded ${} expressions which reference data from the quote objects returned from an AJAX call on the server. You can embed any JavaScript or value expression in these template expressions. There are also a number of structural commands like {{if}} and {{each}} that provide for rudimentary logic inside of your templates as well as commands ({{tmpl}} and {{wrap}}) for nesting templates. You can find more about the full set of markup expressions available in the documentation. To load up this data you can use code like the following: <script type="text/javascript"> //var Proxy = new ServiceProxy("../PageMethods/PageMethodsService.asmx/"); $(document).ready(function () { $("#btnGetQuotes").click(GetQuotes); }); function GetQuotes() { var symbols = $("#txtSymbols").val().split(","); $.ajax({ url: "../PageMethods/PageMethodsService.asmx/GetStockQuotes", data: JSON.stringify({ symbols: symbols }), // parameter map type: "POST", // data has to be POSTed contentType: "application/json", timeout: 10000, dataType: "json", success: function (result) { var quotes = result.d; var jEl = $("#stockTemplate").tmpl(quotes); $("#quoteDisplay").empty().append(jEl); }, error: function (xhr, status) { alert(status + "\r\n" + xhr.responseText); } }); }; </script> In this case an ASMX AJAX service is called to retrieve the stock quotes. The service returns an array of quote objects. The result is returned as an object with the .d property (in Microsoft service style) that returns the actual array of quotes. The template is applied with: var jEl = $("#stockTemplate").tmpl(quotes); which selects the template script tag and uses the .tmpl() function to apply the data to it. The result is a jQuery matched set of elements that can then be appended to the quote display element in the page. The template is merged against an array in this example. When the result is an array the template is automatically applied to each each array item. If you pass a single data item – like say a stock quote – the template works exactly the same way but is applied only once. Templates also have access to a $data item which provides the current data item and information about the tempalte that is currently executing. This makes it possible to keep context within the context of the template itself and also to pass context from a parent template to a child template which is very powerful. Templates can be evaluated by using the template selector and calling the .tmpl() function on the jQuery matched set as shown above or you can use the static $.tmpl() function to provide a template as a string. This allows you to dynamically create templates in code or – more likely – to load templates from the server via AJAX calls. In short there are options The above shows off some of the basics, but there’s much for functionality available in the template engine. Check the documentation link for more information and links to additional examples. The plug-in download also comes with a number of examples that demonstrate functionality. jQuery templates will become a native component in jQuery Core 1.5, so it’s definitely worthwhile checking out the engine today and get familiar with this interface. As much as I’m stoked about templating becoming part of the jQuery core because it’s such an integral part of many applications, there are also a couple shortcomings in the current incarnation: Lack of Error Handling Currently if you embed an expression that is invalid it’s simply not rendered. There’s no error rendered into the template nor do the various  template functions throw errors which leaves finding of bugs as a runtime exercise. I would like some mechanism – optional if possible – to be able to get error info of what is failing in a template when it’s rendered. No String Output Templates are always rendered into a jQuery matched set and there’s no way that I can see to directly render to a string. String output can be useful for debugging as well as opening up templating for creating non-HTML string output. Limited JavaScript Access Unlike John Resig’s original MicroTemplating Engine which was entirely based on JavaScript code generation these templates are limited to a few structured commands that can ‘execute’. There’s no code execution inside of script code which means you’re limited to calling expressions available in global objects or the data item passed in. This may or may not be a big deal depending on the complexity of your template logic. Error handling has been discussed quite a bit and it’s likely there will be some solution to that particualar issue by the time jQuery templates ship. The others are relatively minor issues but something to think about anyway. jQuery Data Link http://api.jquery.com/category/plugins/data-link/ jQuery Data Link provides the ability to do two-way data binding between input controls and an underlying object’s properties. The typical scenario is linking a textbox to a property of an object and have the object updated when the text in the textbox is changed and have the textbox change when the value in the object or the entire object changes. The plug-in also supports converter functions that can be applied to provide the conversion logic from string to some other value typically necessary for mapping things like textbox string input to say a number property and potentially applying additional formatting and calculations. In theory this sounds great, however in reality this plug-in has some serious usability issues. Using the plug-in you can do things like the following to bind data: person = { firstName: "rick", lastName: "strahl"}; $(document).ready( function() { // provide for two-way linking of inputs $("form").link(person); // bind to non-input elements explicitly $("#objFirst").link(person, { firstName: { name: "objFirst", convertBack: function (value, source, target) { $(target).text(value); } } }); $("#objLast").link(person, { lastName: { name: "objLast", convertBack: function (value, source, target) { $(target).text(value); } } }); }); This code hooks up two-way linking between a couple of textboxes on the page and the person object. The first line in the .ready() handler provides mapping of object to form field with the same field names as properties on the object. Note that .link() does NOT bind items into the textboxes when you call .link() – changes are mapped only when values change and you move out of the field. Strike one. The two following commands allow manual binding of values to specific DOM elements which is effectively a one-way bind. You specify the object and a then an explicit mapping where name is an ID in the document. The converter is required to explicitly assign the value to the element. Strike two. You can also detect changes to the underlying object and cause updates to the input elements bound. Unfortunately the syntax to do this is not very natural as you have to rely on the jQuery data object. To update an object’s properties and get change notification looks like this: function updateFirstName() { $(person).data("firstName", person.firstName + " (code updated)"); } This works fine in causing any linked fields to be updated. In the bindings above both the firstName input field and objFirst DOM element gets updated. But the syntax requires you to use a jQuery .data() call for each property change to ensure that the changes are tracked properly. Really? Sure you’re binding through multiple layers of abstraction now but how is that better than just manually assigning values? The code savings (if any) are going to be minimal. As much as I would like to have a WPF/Silverlight/Observable-like binding mechanism in client script, this plug-in doesn’t help much towards that goal in its current incarnation. While you can bind values, the ‘binder’ is too limited to be really useful. If initial values can’t be assigned from the mappings you’re going to end up duplicating work loading the data using some other mechanism. There’s no easy way to re-bind data with a different object altogether since updates trigger only through the .data members. Finally, any non-input elements have to be bound via code that’s fairly verbose and frankly may be more voluminous than what you might write by hand for manual binding and unbinding. Two way binding can be very useful but it has to be easy and most importantly natural. If it’s more work to hook up a binding than writing a couple of lines to do binding/unbinding this sort of thing helps very little in most scenarios. In talking to some of the developers the feature set for Data Link is not complete and they are still soliciting input for features and functionality. If you have ideas on how you want this feature to be more useful get involved and post your recommendations. As it stands, it looks to me like this component needs a lot of love to become useful. For this component to really provide value, bindings need to be able to be refreshed easily and work at the object level, not just the property level. It seems to me we would be much better served by a model binder object that can perform these binding/unbinding tasks in bulk rather than a tool where each link has to be mapped first. I also find the choice of creating a jQuery plug-in questionable – it seems a standalone object – albeit one that relies on the jQuery library – would provide a more intuitive interface than the current forcing of options onto a plug-in style interface. Out of the three Microsoft created components this is by far the least useful and least polished implementation at this point. jQuery Globalization http://github.com/jquery/jquery-global Globalization in JavaScript applications often gets short shrift and part of the reason for this is that natively in JavaScript there’s little support for formatting and parsing of numbers and dates. There are a number of JavaScript libraries out there that provide some support for globalization, but most are limited to a particular portion of globalization. As .NET developers we’re fairly spoiled by the richness of APIs provided in the framework and when dealing with client development one really notices the lack of these features. While you may not necessarily need to localize your application the globalization plug-in also helps with some basic tasks for non-localized applications: Dealing with formatting and parsing of dates and time values. Dates in particular are problematic in JavaScript as there are no formatters whatsoever except the .toString() method which outputs a verbose and next to useless long string. With the globalization plug-in you get a good chunk of the formatting and parsing functionality that the .NET framework provides on the server. You can write code like the following for example to format numbers and dates: var date = new Date(); var output = $.format(date, "MMM. dd, yy") + "\r\n" + $.format(date, "d") + "\r\n" + // 10/25/2010 $.format(1222.32213, "N2") + "\r\n" + $.format(1222.33, "c") + "\r\n"; alert(output); This becomes even more useful if you combine it with templates which can also include any JavaScript expressions. Assuming the globalization plug-in is loaded you can create template expressions that use the $.format function. Here’s the template I used earlier for the stock quote again with a couple of formats applied: <script id="stockTemplate" type="text/x-jquery-tmpl"> <div id="divStockQuote" class="errordisplay" style="width: 500px;"> <div class="label">Company:</div><div><b>${Company}(${Symbol})</b></div> <div class="label">Last Price:</div> <div>${$.format(LastPrice,"N2")}</div> <div class="label">Net Change:</div><div> {{if NetChange > 0}} <b style="color:green" >${NetChange}</b> {{else}} <b style="color:red" >${NetChange}</b> {{/if}} </div> <div class="label">Last Update:</div> <div>${$.format(LastQuoteTime,"MMM dd, yyyy")}</div> </div> </script> There are also parsing methods that can parse dates and numbers from strings into numbers easily: alert($.parseDate("25.10.2010")); alert($.parseInt("12.222")); // de-DE uses . for thousands separators As you can see culture specific options are taken into account when parsing. The globalization plugin provides rich support for a variety of locales: Get a list of all available cultures Query cultures for culture items (like currency symbol, separators etc.) Localized string names for all calendar related items (days of week, months) Generated off of .NET’s supported locales In short you get much of the same functionality that you already might be using in .NET on the server side. The plugin includes a huge number of locales and an Globalization.all.min.js file that contains the text defaults for each of these locales as well as small locale specific script files that define each of the locale specific settings. It’s highly recommended that you NOT use the huge globalization file that includes all locales, but rather add script references to only those languages you explicitly care about. Overall this plug-in is a welcome helper. Even if you use it with a single locale (like en-US) and do no other localization, you’ll gain solid support for number and date formatting which is a vital feature of many applications. Changes for Microsoft It’s good to see Microsoft coming out of its shell and away from the ‘not-built-here’ mentality that has been so pervasive in the past. It’s especially good to see it applied to jQuery – a technology that has stood in drastic contrast to Microsoft’s own internal efforts in terms of design, usage model and… popularity. It’s great to see that Microsoft is paying attention to what customers prefer to use and supporting the customer sentiment – even if it meant drastically changing course of policy and moving into a more open and sharing environment in the process. The additional jQuery support that has been introduced in the last two years certainly has made lives easier for many developers on the ASP.NET platform. It’s also nice to see Microsoft submitting proposals through the standard jQuery process of plug-ins and getting accepted for various very useful projects. Certainly the jQuery Templates plug-in is going to be very useful to many especially since it will be baked into the jQuery core in jQuery 1.5. I hope we see more of this type of involvement from Microsoft in the future. Kudos!© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery  ASP.NET

  • Why is Java EE 6 better than Spring ?

    - by arungupta
    Java EE 6 was released over 2 years ago and now there are 14 compliant application servers. In all my talks around the world, a question that is frequently asked is Why should I use Java EE 6 instead of Spring ? There are already several blogs covering that topic: Java EE wins over Spring by Bill Burke Why will I use Java EE instead of Spring in new Enterprise Java projects in 2012 ? by Kai Waehner (more discussion on TSS) Spring to Java EE migration (Part 1 and 2, 3 and 4 coming as well) by David Heffelfinger Spring to Java EE - A Migration Experience by Lincoln Baxter Migrating Spring to Java EE 6 by Bert Ertman and Paul Bakker at NLJUG Moving from Spring to Java EE 6 - The Age of Frameworks is Over at TSS Java EE vs Spring Shootout by Rohit Kelapure and Reza Rehman at JavaOne 2011 Java EE 6 and the Ewoks by Murat Yener Definite excuse to avoid Spring forever - Bert Ertman and Arun Gupta I will try to share my perspective in this blog. First of all, I'd like to start with a note: Thank you Spring framework for filling the interim gap and providing functionality that is now included in the mainstream Java EE 6 application servers. The Java EE platform has evolved over the years learning from frameworks like Spring and provides all the functionality to build an enterprise application. Thank you very much Spring framework! While Spring was revolutionary in its time and is still very popular and quite main stream in the same way Struts was circa 2003, it really is last generation's framework - some people are even calling it legacy. However my theory is "code is king". So my approach is to build/take a simple Hello World CRUD application in Java EE 6 and Spring and compare the deployable artifacts. I started looking at the official tutorial Developing a Spring Framework MVC Application Step-by-Step but it is using the older version 2.5. I wasn't able to find any updated version in the current 3.1 release. Next, I downloaded Spring Tool Suite and thought that would provide some template samples to get started. A least a quick search did not show any handy tutorials - either video or text-based. So I searched and found a link to their SVN repository at src.springframework.org/svn/spring-samples/. I tried the "mvc-basic" sample and the generated WAR file was 4.43 MB. While it was named a "basic" sample it seemed to come with 19 different libraries bundled but it was what I could find: ./WEB-INF/lib/aopalliance-1.0.jar./WEB-INF/lib/hibernate-validator-4.1.0.Final.jar./WEB-INF/lib/jcl-over-slf4j-1.6.1.jar./WEB-INF/lib/joda-time-1.6.2.jar./WEB-INF/lib/joda-time-jsptags-1.0.2.jar./WEB-INF/lib/jstl-1.2.jar./WEB-INF/lib/log4j-1.2.16.jar./WEB-INF/lib/slf4j-api-1.6.1.jar./WEB-INF/lib/slf4j-log4j12-1.6.1.jar./WEB-INF/lib/spring-aop-3.0.5.RELEASE.jar./WEB-INF/lib/spring-asm-3.0.5.RELEASE.jar./WEB-INF/lib/spring-beans-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-support-3.0.5.RELEASE.jar./WEB-INF/lib/spring-core-3.0.5.RELEASE.jar./WEB-INF/lib/spring-expression-3.0.5.RELEASE.jar./WEB-INF/lib/spring-web-3.0.5.RELEASE.jar./WEB-INF/lib/spring-webmvc-3.0.5.RELEASE.jar./WEB-INF/lib/validation-api-1.0.0.GA.jar And it is not even using any database! The app deployed fine on GlassFish 3.1.2 but the "@Controller Example" link did not work as it was missing the context root. With a bit of tweaking I could deploy the application and assume that the account got created because no error was displayed in the browser or server log. Next I generated the WAR for "mvc-ajax" and the 5.1 MB WAR had 20 JARs (1 removed, 2 added): ./WEB-INF/lib/aopalliance-1.0.jar./WEB-INF/lib/hibernate-validator-4.1.0.Final.jar./WEB-INF/lib/jackson-core-asl-1.6.4.jar./WEB-INF/lib/jackson-mapper-asl-1.6.4.jar./WEB-INF/lib/jcl-over-slf4j-1.6.1.jar./WEB-INF/lib/joda-time-1.6.2.jar./WEB-INF/lib/jstl-1.2.jar./WEB-INF/lib/log4j-1.2.16.jar./WEB-INF/lib/slf4j-api-1.6.1.jar./WEB-INF/lib/slf4j-log4j12-1.6.1.jar./WEB-INF/lib/spring-aop-3.0.5.RELEASE.jar./WEB-INF/lib/spring-asm-3.0.5.RELEASE.jar./WEB-INF/lib/spring-beans-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-3.0.5.RELEASE.jar./WEB-INF/lib/spring-context-support-3.0.5.RELEASE.jar./WEB-INF/lib/spring-core-3.0.5.RELEASE.jar./WEB-INF/lib/spring-expression-3.0.5.RELEASE.jar./WEB-INF/lib/spring-web-3.0.5.RELEASE.jar./WEB-INF/lib/spring-webmvc-3.0.5.RELEASE.jar./WEB-INF/lib/validation-api-1.0.0.GA.jar 2 more JARs for just doing Ajax. Anyway, deploying this application gave the following error: Caused by: java.lang.NoSuchMethodError: org.codehaus.jackson.map.SerializationConfig.<init>(Lorg/codehaus/jackson/map/ClassIntrospector;Lorg/codehaus/jackson/map/AnnotationIntrospector;Lorg/codehaus/jackson/map/introspect/VisibilityChecker;Lorg/codehaus/jackson/map/jsontype/SubtypeResolver;)V    at org.springframework.samples.mvc.ajax.json.ConversionServiceAwareObjectMapper.<init>(ConversionServiceAwareObjectMapper.java:20)    at org.springframework.samples.mvc.ajax.json.JacksonConversionServiceConfigurer.postProcessAfterInitialization(JacksonConversionServiceConfigurer.java:40)    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyBeanPostProcessorsAfterInitialization(AbstractAutowireCapableBeanFactory.java:407) Seems like some incorrect repos in the "pom.xml". Next one is "mvc-showcase" and the 6.49 MB WAR now has 28 JARs as shown below: ./WEB-INF/lib/aopalliance-1.0.jar./WEB-INF/lib/aspectjrt-1.6.10.jar./WEB-INF/lib/commons-fileupload-1.2.2.jar./WEB-INF/lib/commons-io-2.0.1.jar./WEB-INF/lib/el-api-2.2.jar./WEB-INF/lib/hibernate-validator-4.1.0.Final.jar./WEB-INF/lib/jackson-core-asl-1.8.1.jar./WEB-INF/lib/jackson-mapper-asl-1.8.1.jar./WEB-INF/lib/javax.inject-1.jar./WEB-INF/lib/jcl-over-slf4j-1.6.1.jar./WEB-INF/lib/jdom-1.0.jar./WEB-INF/lib/joda-time-1.6.2.jar./WEB-INF/lib/jstl-api-1.2.jar./WEB-INF/lib/jstl-impl-1.2.jar./WEB-INF/lib/log4j-1.2.16.jar./WEB-INF/lib/rome-1.0.0.jar./WEB-INF/lib/slf4j-api-1.6.1.jar./WEB-INF/lib/slf4j-log4j12-1.6.1.jar./WEB-INF/lib/spring-aop-3.1.0.RELEASE.jar./WEB-INF/lib/spring-asm-3.1.0.RELEASE.jar./WEB-INF/lib/spring-beans-3.1.0.RELEASE.jar./WEB-INF/lib/spring-context-3.1.0.RELEASE.jar./WEB-INF/lib/spring-context-support-3.1.0.RELEASE.jar./WEB-INF/lib/spring-core-3.1.0.RELEASE.jar./WEB-INF/lib/spring-expression-3.1.0.RELEASE.jar./WEB-INF/lib/spring-web-3.1.0.RELEASE.jar./WEB-INF/lib/spring-webmvc-3.1.0.RELEASE.jar./WEB-INF/lib/validation-api-1.0.0.GA.jar The app at least deployed and showed results this time. But still no database! Next I tried building "jpetstore" and got the error: [ERROR] Failed to execute goal on project org.springframework.samples.jpetstore:Could not resolve dependencies for project org.springframework.samples:org.springframework.samples.jpetstore:war:1.0.0-SNAPSHOT: Failed to collect dependencies for [commons-fileupload:commons-fileupload:jar:1.2.1 (compile), org.apache.struts:com.springsource.org.apache.struts:jar:1.2.9 (compile), javax.xml.rpc:com.springsource.javax.xml.rpc:jar:1.1.0 (compile), org.apache.commons:com.springsource.org.apache.commons.dbcp:jar:1.2.2.osgi (compile), commons-io:commons-io:jar:1.3.2 (compile), hsqldb:hsqldb:jar:1.8.0.7 (compile), org.apache.tiles:tiles-core:jar:2.2.0 (compile), org.apache.tiles:tiles-jsp:jar:2.2.0 (compile), org.tuckey:urlrewritefilter:jar:3.1.0 (compile), org.springframework:spring-webmvc:jar:3.0.0.BUILD-SNAPSHOT (compile), org.springframework:spring-orm:jar:3.0.0.BUILD-SNAPSHOT (compile), org.springframework:spring-context-support:jar:3.0.0.BUILD-SNAPSHOT (compile), org.springframework.webflow:spring-js:jar:2.0.7.RELEASE (compile), org.apache.ibatis:com.springsource.com.ibatis:jar:2.3.4.726 (runtime), com.caucho:com.springsource.com.caucho:jar:3.2.1 (compile), org.apache.axis:com.springsource.org.apache.axis:jar:1.4.0 (compile), javax.wsdl:com.springsource.javax.wsdl:jar:1.6.1 (compile), javax.servlet:jstl:jar:1.2 (runtime), org.aspectj:aspectjweaver:jar:1.6.5 (compile), javax.servlet:servlet-api:jar:2.5 (provided), javax.servlet.jsp:jsp-api:jar:2.1 (provided), junit:junit:jar:4.6 (test)]: Failed to read artifact descriptor for org.springframework:spring-webmvc:jar:3.0.0.BUILD-SNAPSHOT: Could not transfer artifact org.springframework:spring-webmvc:pom:3.0.0.BUILD-SNAPSHOT from/to JBoss repository (http://repository.jboss.com/maven2): Access denied to: http://repository.jboss.com/maven2/org/springframework/spring-webmvc/3.0.0.BUILD-SNAPSHOT/spring-webmvc-3.0.0.BUILD-SNAPSHOT.pom It appears the sample is broken - maybe I was pulling from the wrong repository - would be great if someone were to point me at a good target to use here. With a 50% hit on samples in this repository, I started searching through numerous blogs, most of which have either outdated information (using XML-heavy Spring 2.5), some piece of configuration (which is a typical "feature" of Spring) is missing, or too much complexity in the sample. I finally found this blog that worked like a charm. This blog creates a trivial Spring MVC 3 application using Hibernate and MySQL. This application performs CRUD operations on a single table in a database using typical Spring technologies.  I downloaded the sample code from the blog, deployed it on GlassFish 3.1.2 and could CRUD the "person" entity. The source code for this application can be downloaded here. More details on the application statistics below. And then I built a similar CRUD application in Java EE 6 using NetBeans wizards in a couple of minutes. The source code for the application can be downloaded here and the WAR here. The Spring Source Tool Suite may also offer similar wizard-driven capabilities but this blog focus primarily on comparing the runtimes. The lack of STS tutorials was slightly disappointing as well. NetBeans however has tons of text-based and video tutorials and tons of material even by the community. One more bit on the download size of tools bundle ... NetBeans 7.1.1 "All" is 211 MB (which includes GlassFish and Tomcat) Spring Tool Suite  2.9.0 is 347 MB (~ 65% bigger) This blog is not about the tooling comparison so back to the Java EE 6 version of the application .... In order to run the Java EE version on GlassFish, copy the MySQL Connector/J to glassfish3/glassfish/domains/domain1/lib/ext directory and create a JDBC connection pool and JDBC resource as: ./bin/asadmin create-jdbc-connection-pool --datasourceclassname \\ com.mysql.jdbc.jdbc2.optional.MysqlDataSource --restype \\ javax.sql.DataSource --property \\ portNumber=3306:user=mysql:password=mysql:databaseName=mydatabase \\ myConnectionPool ./bin/asadmin create-jdbc-resource --connectionpoolid myConnectionPool jdbc/myDataSource I generated WARs for the two projects and the table below highlights some differences between them: Java EE 6 Spring WAR File Size 0.021030 MB 10.87 MB (~516x) Number of files 20 53 (> 2.5x) Bundled libraries 0 36 Total size of libraries 0 12.1 MB XML files 3 5 LoC in XML files 50 (11 + 15 + 24) 129 (27 + 46 + 16 + 11 + 19) (~ 2.5x) Total .properties files 1 Bundle.properties 2 spring.properties, log4j.properties Cold Deploy 5,339 ms 11,724 ms Second Deploy 481 ms 6,261 ms Third Deploy 528 ms 5,484 ms Fourth Deploy 484 ms 5,576 ms Runtime memory ~73 MB ~101 MB Some points worth highlighting from the table ... 516x WAR file, 10x deployment time - With 12.1 MB of libraries (for a very basic application) bundled in your application, the WAR file size and the deployment time will naturally go higher. The WAR file for Spring-based application is 516x bigger and the deployment time is double during the first deployment and ~ 10x during subsequent deployments. The Java EE 6 application is fully portable and will run on any Java EE 6 compliant application server. 36 libraries in the WAR - There are 14 Java EE 6 compliant application servers today. Each of those servers provide all the functionality like transactions, dependency injection, security, persistence, etc typically required of an enterprise or web application. There is no need to bundle 36 libraries worth 12.1 MB for a trivial CRUD application. These 14 compliant application servers provide all the functionality baked in. Now you can also deploy these libraries in the container but then you don't get the "portability" offered by Spring in that case. Does your typical Spring deployment actually do that ? 3x LoC in XML - The number of XML files is about 1.6x and the LoC is ~ 2.5x. So much XML seems circa 2003 when the Java language had no annotations. The XML files can be further reduced, e.g. faces-config.xml can be replaced without providing i18n, but I just want to compare stock applications. Memory usage - Both the applications were deployed on default GlassFish 3.1.2 installation and any additional memory consumed as part of deployment/access was attributed to the application. This is by no means scientific but at least provides an initial ballpark. This area definitely needs more investigation. Another table that compares typical Java EE 6 compliant application servers and the custom-stack created for a Spring application ... Java EE 6 Spring Web Container ? 53 MB (tcServer 2.6.3 Developer Edition) Security ? 12 MB (Spring Security 3.1.0) Persistence ? 6.3 MB (Hibernate 4.1.0, required) Dependency Injection ? 5.3 MB (Framework) Web Services ? 796 KB (Spring WS 2.0.4) Messaging ? 3.4 MB (RabbitMQ Server 2.7.1) 936 KB (Java client 936) OSGi ? 1.3 MB (Spring OSGi 1.2.1) GlassFish and WebLogic (starting at 33 MB) 83.3 MB There are differentiating factors on both the stacks. But most of the functionality like security, persistence, and dependency injection is baked in a Java EE 6 compliant application server but needs to be individually managed and patched for a Spring application. This very quickly leads to a "stack explosion". The Java EE 6 servers are tested extensively on a variety of platforms in different combinations whereas a Spring application developer is responsible for testing with different JDKs, Operating Systems, Versions, Patches, etc. Oracle has both the leading OSS lightweight server with GlassFish and the leading enterprise Java server with WebLogic Server, both Java EE 6 and both with lightweight deployment options. The Web Container offered as part of a Java EE 6 application server not only deploys your enterprise Java applications but also provide operational management, diagnostics, and mission-critical capabilities required by your applications. The Java EE 6 platform also introduced the Web Profile which is a subset of the specifications from the entire platform. It is targeted at developers of modern web applications offering a reasonably complete stack, composed of standard APIs, and is capable out-of-the-box of addressing the needs of a large class of Web applications. As your applications grow, the stack can grow to the full Java EE 6 platform. The GlassFish Server Web Profile starting at 33MB (smaller than just the non-standard tcServer) provides most of the functionality typically required by a web application. WebLogic provides battle-tested functionality for a high throughput, low latency, and enterprise grade web application. No individual managing or patching, all tested and commercially supported for you! Note that VMWare does have a server, tcServer, but it is non-standard and not even certified to the level of the standard Web Profile most customers expect these days. Customers who choose this risk proprietary lock-in since VMWare does not seem to want to formally certify with either Java EE 6 Enterprise Platform or with Java EE 6 Web Profile but of course it would be great if they were to join the community and help their customers reduce the risk of deploying on VMWare software. Some more points to help you decide choose between Java EE 6 and Spring ... Freedom to choose container - There are 14 Java EE 6 compliant application servers today, with a variety of open source and commercial offerings. A Java EE 6 application can be deployed on any of those containers. So if you deployed your application on GlassFish today and would like to scale up with your demands then you can deploy the same application to WebLogic. And because of the portability of a Java EE 6 application, you can even take it a different vendor altogether. Spring requires a runtime which could be any of these app servers as well. But why use Spring when all the required functionality is already baked into the application server itself ? Spring also has a different definition of portability where they claim to bundle all the libraries in the WAR file and move to any application server. But we saw earlier how bloated that archive could be. The equivalent features in Spring runtime offerings (mainly tcServer) are not all open source, not as mature, and often require manual assembly.  Vendor choice - The Java EE 6 platform is created using the Java Community Process where all the big players like Oracle, IBM, RedHat, and Apache are conritbuting to make the platform successful. Each application server provides the basic Java EE 6 platform compliance and has its own competitive offerings. This allows you to choose an application server for deploying your Java EE 6 applications. If you are not happy with the support or feature of one vendor then you can move your application to a different vendor because of the portability promise offered by the platform. Spring is a set of products from a single company, one price book, one support organization, one sustaining organization, one sales organization, etc. If any of those cause a customer headache, where do you go ? Java EE, backed by multiple vendors, is a safer bet for those that are risk averse. Production support - With Spring, typically you need to get support from two vendors - VMWare and the container provider. With Java EE 6, all of this is typically provided by one vendor. For example, Oracle offers commercial support from systems, operating systems, JDK, application server, and applications on top of them. VMWare certainly offers complete production support but do you really want to put all your eggs in one basket ? Do you really use tcServer ? ;-) Maintainability - With Spring, you are likely building your own distribution with multiple JAR files, integrating, patching, versioning, etc of all those components. Spring's claim is that multiple JAR files allow you to go à la carte and pick the latest versions of different components. But who is responsible for testing whether all these versions work together ? Yep, you got it, its YOU! If something does not work, who patches and maintains the JARs ? Of course, you! Commercial support for such a configuration ? On your own! The Java EE application servers manage all of this for you and provide a well-tested and commercially supported bundle. While it is always good to realize that there is something new and improved that updates and replaces older frameworks like Spring, the good news is not only does a Java EE 6 container offer what is described here, most also will let you deploy and run your Spring applications on them while you go through an upgrade to a more modern architecture. End result, you get the best of both worlds - keeping your legacy investment but moving to a more agile, lightweight world of Java EE 6. A message to the Spring lovers ... The complexity in J2EE 1.2, 1.3, and 1.4 led to the genesis of Spring but that was in 2004. This is 2012 and the name has changed to "Java EE 6" :-) There are tons of improvements in the Java EE platform to make it easy-to-use and powerful. Some examples: Adding @Stateless on a POJO makes it an EJB EJBs can be packaged in a WAR with no special packaging or deployment descriptors "web.xml" and "faces-config.xml" are optional in most of the common cases Typesafe dependency injection is now part of the Java EE platform Add @Path on a POJO allows you to publish it as a RESTful resource EJBs can be used as backing beans for Facelets-driven JSF pages providing full MVC Java EE 6 WARs are known to be kilobytes in size and deployed in milliseconds Tons of other simplifications in the platform and application servers So if you moved away from J2EE to Spring many years ago and have not looked at Java EE 6 (which has been out since Dec 2009) then you should definitely try it out. Just be at least aware of what other alternatives are available instead of restricting yourself to one stack. Here are some workshops and screencasts worth trying: screencast #37 shows how to build an end-to-end application using NetBeans screencast #36 builds the same application using Eclipse javaee-lab-feb2012.pdf is a 3-4 hours self-paced hands-on workshop that guides you to build a comprehensive Java EE 6 application using NetBeans Each city generally has a "spring cleanup" program every year. It allows you to clean up the mess from your house. For your software projects, you don't need to wait for an annual event, just get started and reduce the technical debt now! Move away from your legacy Spring-based applications to a lighter and more modern approach of building enterprise Java applications using Java EE 6.
