  • Will this web service accept both raw xml and an object?

    - by ChadNC
    We have a web service that provides auto insurance quotes and a company that provides an insurance agency management system would like to use the web service for thier client but they want to pass the web service raw xml instead of using the wsdl to create a port, the object the service expects and calling the web method. The web service has performed flawlessly by creating an object like so com.insurance.quotesvc.AgencyQuote service = new com.insurance.quotesvc.AgencyQuote(); com.insurance.quotesvc.QuotePortType port = service.getQuotePortType(); com.insurance.quotesvc.schemas.request.ACORD parameter = null; Then create initialize the request object with the other objects that make up the response. parameter = factory.createACORD(); parameter.setSignonRq(signOn); parameter.setInsurancesSvcRq(svcRq); And send the request to the web service. com.insurance.quotesvc.schemas.response.ACORD result = null; result = port.requestQuote(parameter); By doing that I am able to easily marshall the request and the result into an xml file and do with them as I wish. So if a client was to send the web service via an http post as raw xml inside of a soap envelope. Would the web service be able to handle the xml without any changes being made to the web service or would there need to be changes made to the web service in order for it to handle a request of that type? The web service is a JAX_WS and we currently have both Java and C# clients consuming the web service using the method described above but now there is another client who wants to send raw xml inside of a soap envelope instead of creating the objects. I feel pretty sure that they will be making the call to the web service using vb. I'm sure I'm missing something obvious but it is eluding me at the moment and any help is greatly appreciated.

  • Schema for storing "binary" values, such as Male/Female, in a database

    - by latentflip
    Intro I am trying to decide how best to set up my database schema for a (Rails) model. I have a model related to money which indicates whether the value is an income (positive cash value) or an expense (negative cash value). I would like separate column(s) to indicate whether it is an income or an expense, rather than relying on whether the value stored is positive or negative. Question: How would you store these values, and why? Have a single column, say Income, and store 1 if it's an income, 0 if it's an expense, null if not known. Have two columns, Income and Expense, setting their values to 1 or 0 as appropriate. Something else? I figure the question is similar to storing a person's gender in a database (ignoring aliens/transgender/etc) hence my title. My thoughts so far Lookup might be easier with a single column, but there is a risk of mistaking 0 (false, expense) for null (unknown). Having seperate columns might be more difficult to maintain (what happens if we end up with a 1 in both columns? Maybe it's not that big a deal which way I go, but it would be great to have any concerns/thoughts raised before I get too far down the line and have to change my code-base because I missed something that should have been obvious! Thanks, Philip

  • Read a text file

    - by Cyprus106
    I have looked everywhere and surprisingly can't find a good solution to this! I've got the following code that is supposed to read a text file and display it's contents. But it's not reading, for some reason. Am I doing something wrong? FTR, I can't use PHP for this. It's gotta be Javascript. var txtFile = new XMLHttpRequest(); txtFile.open("GET", "http://www.mysite.com/todaysTrivia.txt", true); txtFile.send(null); txtFile.onreadystatechange = function() { if (txtFile.readyState == 4) { // Makes sure the document is ready to parse. alert(txtFile.responseText+" - "+txtFile.status); //if (txtFile.status === 200) { // Makes sure it's found the file. var doc = document.getElementById("Trivia-Widget"); if (doc) { doc.innerHTML = txtFile.responseText ; } //} } txtFile.send(null); } Any good ideas what I'm doing wrong? It just keeps givimg me a zero status. EDIT: I guess it would be a good idea to explain why I need this code. It's basically a widget that other folks can put on their own websites that grabs a line of text from my website and displays it on theirs. The problem is that it really can't be server-side since I've got zero control over everyone else's sites that use this.

  • Custom android preference type loses focus when typing

    - by Brian
    I created a simple preference class that shows an AutoCompleteTextView control and it displays properly but when i focus on the AutoCompleteTextView and start typing it brings up the keyboard but then immediately loses focus on the control. Any idea why this loses focus? Here's what i did to create the view. the inflated layout is just a basic linear layout with a title textview in it. I could change it to a dialog preference instead I guess but it'd be smoother if it could be part of the base view. @Override protected View onCreateView(ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.base_preference, null); if (mHint != null) { TextView hintView = (TextView) layout.findViewById(R.id.PreferenceHintTextView); hintView.setText(mHint); } TextView titleView = (TextView) layout.findViewById(R.id.PreferenceTitleTextView); titleView.setText(getTitle()); AutoCompleteTextView inputView = new AutoCompleteTextView(getContext()); inputView.setGravity(Gravity.FILL_HORIZONTAL); ArrayAdapter<CharSequence> adapter = new ArrayAdapter<CharSequence>(getContext(), R.layout.auto_complete_text_list_item, getEntries()); inputView.setAdapter(adapter); inputView.setThreshold(1); inputView.setOnItemSelectedListener(this); layout.addView(inputView); return layout; }

  • Mysql count and sum from two diferent tables

    - by Agent_x
    Hi all, i have a problem with some querys in php and mysql: I have 2 diferent tables with one field in common: table 1 id | hits | num_g | cats | usr_id |active 1 | 10 | 11 | 1 | 53 | 1 2 | 13 | 16 | 3 | 53 | 1 1 | 10 | 22 | 1 | 22 | 1 1 | 10 | 21 | 3 | 22 | 1 1 | 2 | 6 | 2 | 11 | 1 1 | 11 | 1 | 1 | 11 | 1 table 2 id | usr_id | points 1 | 53 | 300 Now i use this statement to sum just the total from the table 1 every id count + 1 too SELECT usr_id, COUNT( id ) + SUM( num_g + hits ) AS tot_h FROM table1 WHERE usr_id!='0' GROUP BY usr_id ASC LIMIT 0 , 15 and i get the total for each usr_id usr_id| tot_h | 53 | 50 22 | 63 11 | 20 until here all is ok, now i have a second table with extra points (table2) I try this: SELECT usr_id, COUNT( id ) + SUM( num_g + hits ) + (SELECT points FROM table2 WHERE usr_id != '0' ) AS tot_h FROM table1 WHERE usr_id != '0' GROUP BY usr_id ASC LIMIT 0 , 15 but it seems to sum the 300 extra points to all users: usr_id| tot_h | 53 | 350 22 | 363 11 | 320 Now how i can get the total like the first try but + the secon table in one statement? because now i have just one entry in the second table but i can be more there. thanks for all the help. =============================================================================== hi thomas thanks for your reply, i think is in the right direction, but im getting weirds results, like usr_id | tot_h 22 | NULL <== i think the null its because that usr_id as no value in the table2 53 | 1033 Its like the second user is getting all the the values. then i try this one: SELECT table1.usr_id, COUNT( table1.id ) + SUM( table1.num_g + table1.hits + table2.points ) AS tot_h FROM table1 LEFT JOIN table2 ON table2.usr_id = table1.usr_id WHERE table1.usr_id != '0' AND table2.usr_id = table1.usr_id GROUP BY table1.usr_id ASC Same result i just get the sum of all values and not by each user, i need something like this result: usr_id | tot_h 53 | 53 <==== plus 300 points on table1 22 | 56 <==== plus 100 points on table2 /////////the result i need //////////// usr_id | tot_h 53 | 353 <==== plus 300 points on table2 22 | 156 <==== plus 100 points on table2 I think the structure need to be something like this Pseudo statements ;) from table1 count all id to get the number of record where the usr_id are then sum hits + num_g and from table2 select the extra points where the usr_id are the same as table1 and get teh result: usr_id | tot_h 53 | 353 22 | 156

  • Unit Testing an Event Firing From a Thread

    - by Dougc
    I'm having a problem unit testing a class which fires events when a thread starts and finishes. A cut down version of the offending source is as follows: public class ThreadRunner { private bool keepRunning; public event EventHandler Started; public event EventHandler Finished; public void StartThreadTest() { this.keepRunning = true; var thread = new Thread(new ThreadStart(this.LongRunningMethod)); thread.Start(); } public void FinishThreadTest() { this.keepRunning = false; } protected void OnStarted() { if (this.Started != null) this.Started(this, new EventArgs()); } protected void OnFinished() { if (this.Finished != null) this.Finished(this, new EventArgs()); } private void LongRunningMethod() { this.OnStarted(); while (this.keepRunning) Thread.Sleep(100); this.OnFinished(); } } I then have a test to check that the Finished event fires after the LongRunningMethod has finished as follows: [TestClass] public class ThreadRunnerTests { [TestMethod] public void CheckFinishedEventFiresTest() { var threadTest = new ThreadRunner(); bool finished = false; object locker = new object(); threadTest.Finished += delegate(object sender, EventArgs e) { lock (locker) { finished = true; Monitor.Pulse(locker); } }; threadTest.StartThreadTest(); threadTest.FinishThreadTest(); lock (locker) { Monitor.Wait(locker, 1000); Assert.IsTrue(finished); } } } So the idea here being that the test will block for a maximum of one second - or until the Finish event is fired - before checking whether the finished flag is set. Clearly I've done something wrong as sometimes the test will pass, sometimes it won't. Debugging seems very difficult as well as the breakpoints I'd expect to be hit (the OnFinished method, for example) don't always seem to be. I'm assuming this is just my misunderstanding of the way threading works, so hopefully someone can enlighten me.

  • Parsing XML elements with dynamic namespace prefix in PHP

    - by BugKiller
    I have the following XML ( you can say SOAP request ) : <SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope> I use the following code and it works fine : <?php $myRequest ='<SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope>'; $xml = simplexml_load_string($myRequest, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $namespaces = $xml->getNameSpaces(true); $soapHeader = $xml->children($namespaces['SOAPENV'])->Header; $myHeader = $soapHeader->children($namespaces['NS'])->myHeader; echo (string)$myHeader->SourceID; ?> The Problem I know the prefix ( SOAPENV + NS ) , but the clients could change the prefix to whatever they want, so they may send me xml document that has ( MY-SOAPENV + MY-NS) prefixes. My Question How can I handle this since the namespace prefixes are not static , how can I parse it ? Thanks

  • Reading lines of data from text files using java

    - by razshan
    I have a text file with x amount of lines. each line holds a integer number. When the user clicks a button, an action is performed via actionlistener where it should list all the values as displayed on the text file. However, right now I have linenum set to 10 implying I already told the code that just work with 10 lines of the text file. So, if my text file has only 3 rows/lines of data...it will list those lines and for rest of the other 7 lines, it will spit out "null". I recall there is a way to use ellipsis to let the program know that you don't know the exact value but at the end it calculates it based on the given information. Where my given information will the number of lines with numbers(data). Below is part of the code. private class thehandler implements ActionListener{ public void actionPerformed(ActionEvent event){ BufferedReader inputFile=null; try { FileReader freader =new FileReader("Data.txt"); inputFile = new BufferedReader(freader); String MAP = ""; int linenum=10; while(linenum > 0) { linenum=linenum-1; MAP = inputFile.readLine();//read the next line until the specfic line is found System.out.println(MAP); } } catch( Exception y ) { y.printStackTrace(); } }}

  • Strange results while measuring delta time on Linux

    - by pachanga
    Folks, could you please explain why I'm getting very strange results from time to time using the the following code: #include <unistd.h> #include <sys/time.h> #include <time.h> #include <stdio.h> int main() { struct timeval start, end; long mtime, seconds, useconds; while(1) { gettimeofday(&start, NULL); usleep(2000); gettimeofday(&end, NULL); seconds = end.tv_sec - start.tv_sec; useconds = end.tv_usec - start.tv_usec; mtime = ((seconds) * 1000 + useconds/1000.0) + 0.5; if(mtime > 10) printf("WTF: %ld\n", mtime); } return 0; } (You can compile and run it with: gcc test.c -o out -lrt && ./out) What I'm experiencing is sporadic big values of mtime variable almost every second or even more often, e.g: $ gcc test.c -o out -lrt && ./out WTF: 14 WTF: 11 WTF: 11 WTF: 11 WTF: 14 WTF: 13 WTF: 13 WTF: 11 WTF: 16 How can this be possible? Is it OS to blame? Does it do too much context switching? But my box is idle( load average: 0.02, 0.02, 0.3).

  • Silverlight Image Data Binding

    - by Alexander
    I am new to Silverlight, and have an issue with binding. I have a class ItemsManager, that has inside its scope another class Item. class ItemsManager { ... class Item : INotifyPropertyChanged { ... private BitmapImage bitmapSource; public BitmapImage BitmapSource { get { return bitmapSource; } set { bitmapSource = value; if(PropertyChanged != null )PropertyChanged("BitmapSource") } } } } I do the following in code to test binding: { ItemsManager.Instance.AddItem("123"); //Items manager started downloading item visual //part (in my case bitmap image png) Binding b = new Binding("Source"); b.Source = ItemsManager.Instance.GetItem("123").BitmapSource; b.BindsDirectlyToSource = true; Image img = new Image(); img.SetBinding(Image.SourceProperty, b); img.Width = (double)100.0; img.Height = (double)100.0; LayoutRoot.Children.Add(img); } Once image is loaded, image doesn't appear. Though, if I set directly after image has been loaded its source, it displays well. I also noticed that PropertyChanged("BitmapSource") never fires, because PropertyChanged is null, like Image never binded to it. I am looking forward to hearing from you!

  • PHP: Adding text to a file

    - by Kevin Duke
    I'm trying to set up authentication on my server, however, I know little about Php. I have a php file filled with users and passwords: function getPassword( $user ) { // the user/password database. For very small groups // of users, you may just get away with expanding this // array. $passwords= array ( 'user1' => 'password1', 'user2' => 'password2', 'user3' => 'password3', 'user4' => 'password4' ); $password = $passwords[ $user ]; if ( NULL == $password ) return NULL; Without manually editing the array of passwords, I want a php file to read in user inputs for usernames and passwords and append it to the array. I have a vague idea of how this could work by looking up documentation: <?php function fwrite_stream($fp, $string) { $fp = fopen('shit.php', 'w'); for ($written = 0; $written < strlen($string); $written += $fwrite) { $fwrite = fwrite($fp, substr($string, $written)); if ($fwrite === false) { return $written; } } return $written; fclose($fp); } ?> How do I tell this to write to the array?

  • What does P mean in Sort(Expression<Func<T, P>> expr, ListSortDirection direction)?

    - by Grasshopper
    I am attempting to use the answer in post: How do you sort an EntitySet<T> to expose an interface so that I can sort an EntitySet with a Binding list. I have created the class below and I get the following compiler error: "The type or namespace 'P' could not be found (are you missing a using directive or assembly reference?). Can someone tell me what the P means and which namespace I need to include to get the method below to compile? I am very new to delegates and lamba expressions. Also, can someone confirm that if I create a BindingList from my EntitySet that any modifications I make to the BindingList will be made to the EntitySet? Basically, I have an EntitySet that I need to sort and make changes to. Then, I will need to persist these changes using the original Entity that the BindingList came from. public class EntitySetBindingWrapper<T> : BindingList<T> { public EntitySetBindingWrapper(BindingList<T> root) : base(root) { } public void Sort(Expression<Func<T, P>> expr, ListSortDirection direction) { if (expr == null) base.RemoveSortCore(); MemberExpression propExpr = expr as MemberExpression; if (propExpr == null) throw new ArgumentException("You must provide a property", "expr"); PropertyDescriptorCollection descriptorCol = TypeDescriptor.GetProperties(typeof(T)); IEnumerable<PropertyDescriptor> descriptors = descriptorCol.Cast<PropertyDescriptor>(); PropertyDescriptor descriptor = descriptors.First(pd => pd.Name == propExpr.Member.Name); base.ApplySortCore(descriptor, direction); } }

  • Synchronize write to two collections

    - by glaz666
    I need to put some value to maps if it is not there yet. The key-value (if set) should always be in two collections (that is put should happen in two maps atomically). I have tried to implement this as follows: private final ConcurrentMap<String, Object> map1 = new ConcurrentHashMap<String, Object>(); private final ConcurrentMap<String, Object> map2 = new ConcurrentHashMap<String, Object>(); public Object putIfAbsent(String key) { Object retval = map1.get(key); if (retval == null) { synchronized (map1) { retval = map1.get(key); if (retval == null) { Object value = new Object(); //or get it somewhere synchronized (map2) { map1.put(key, value); map2.put(key, new Object()); } retval = value; } } } return retval; } public void doSomething(String key) { Object obj1 = map1.get(key); Object obj2 = map2.get(key); //do smth } Will that work fine in all cases?

  • Callers block until getFoo() has a value ready?

    - by Sean Owen
    I have a Java Thread which exposes a property which other threads want to access: class MyThread extends Thread { private Foo foo; ... Foo getFoo() { return foo; } ... public void run() { ... foo = makeTheFoo(); ... } } The problem is that it takes some short time from the time this runs until foo is available. Callers may call getFoo() before this and get a null. I'd rather they simply block, wait, and get the value once initialization has occurred. (foo is never changed afterwards.) It will be a matter of milliseconds until it's ready, so I'm comfortable with this approach. Now, I can make this happen with wait() and notifyAll() and there's a 95% chance I'll do it right. But I'm wondering how you all would do it; is there a primitive in java.util.concurrent that would do this, that I've missed? Or, how would you structure it? Yes, make foo volatile. Yes, synchronize on an internal lock Object and put the check in a while loop until it's not null. Am I missing anything?

  • Why would using a Temp table be faster than a nested query?

    - by Mongus Pong
    We are trying to optimise some of our queries. One query is doing the following: SELECT t.TaskID, t.Name as Task, '' as Tracker, t.ClientID, (<complex subquery>) Date, INTO [#Gadget] FROM task t SELECT TOP 500 TaskID, Task, Tracker, ClientID, dbo.GetClientDisplayName(ClientID) as Client FROM [#Gadget] order by CASE WHEN Date IS NULL THEN 1 ELSE 0 END , Date ASC DROP TABLE [#Gadget] (I have removed the complex subquery, cos I dont think its relevant other than to explain why this query has been done as a two stage process.) Now I would have thought it would be far more efficient to merge this down into a single query using subqueries as : SELECT TOP 500 TaskID, Task, Tracker, ClientID, dbo.GetClientDisplayName(ClientID) FROM ( SELECT t.TaskID, t.Name as Task, '' as Tracker, t.ClientID, (<complex subquery>) Date, FROM task t ) as sub order by CASE WHEN Date IS NULL THEN 1 ELSE 0 END , Date ASC This would give the optimiser better information to work out what was going on and avoid any temporary tables. It should be faster. But it turns out it is a lot slower. 8 seconds vs under 5 seconds. I cant work out why this would be the case as all my knowledge of databases imply that subqueries would always be faster than using temporary tables. Can anyone explain what could be going on!?!?

    Hi all, I'm quite new to drawing shapes, graphics, bitmaps etc. I googled for a few days,but still havent got a real clue what to do, so please help me: I want to draw a floorplan with certain objects(represented as circles) moving on it. When I click on a object, it needs to show something. So far, I ve been able to draw some circles on a graphic and been able to move the dots by clearing the graphic every time. Ofcourse, this isnt a real solution, since I cant keep track of the different objects on the floorplan (which i need for my clickevent and movings). I hope I explained my problem ok here. This is the (stripped version of the) sourcecode that gets called every second: (dev (of type Device) is the object i want to draw) Graphics gfx = FloorplanTabPage.CreateGraphics(); gfx.Clear(Color.White); foreach (Device dev in _deviceList) { Pen myPen = new Pen(Color.Black) { Width = 10 }; dev.InRoom != null) { myPen.Color = Color.DarkOrchid; int x = dev.InRoom.XPos + (dev.InRoom.Width / 2) - 5; int y = (dev.InRoom.YPos + (dev.InRoom.Height / 2) - 5; if (dev.ToRoom != null) { x = (x + (dev.ToRoom.XPos + (dev.ToRoom.Width / 2)) / 2; y = (y + (dev.ToRoom.YPos + (dev.ToRoom.Height / 2)) / 2; } gfx.DrawEllipse(myPen, x, y, 10, 10); gfx.DrawString(dev.Name, new Font("Arial", 10), Brushes.Purple, x, y - 15); } }

  • How can I keep the the logic to translate a ViewModel's values to a Where clause to apply to a linq query out of My Controller?

    - by Mr. Manager
    This same problem keeps cropping up. I have a viewModel that doesn't have any persistent backing. It is just a ViewModel to generate a search input form. I want to build a large where clause from the values the user entered. If the Action Accepts as a parameter SearchViewModel How do I do this without passing my viewModel to my service layer? Service shouldn't know about ViewModels right? Oh and if I serialize it, then it would be a big string and the key/values would be strongly typed. SearchViewModel this is just a snippet. [Display(Name="Address")] public string AddressKeywords { get; set; } /// <summary> /// Gets or sets the census. /// </summary> public string Census { get; set; } /// <summary> /// Gets or sets the lot block sub. /// </summary> public string LotBlockSub { get; set; } /// <summary> /// Gets or sets the owner keywords. /// </summary> [Display(Name="Owner")] public string OwnerKeywords { get; set; } In my controller action I was thinking of something like this. but I would think all this logic doesn't belong in my Controller. ActionResult GetSearchResults(SearchViewModel model){ var query = service.GetAllParcels(); if(model.Census != null){ query = query.Where(x=>x.Census == model.Census); } if (model.OwnerKeywords != null){ query = query.Where(x=>x.Owners == model.OwnerKeywords); } return View(query.ToList()); }

  • EventAggregator, is it thread-safe?

    - by pfaz
    Is this thread-safe? The EventAggregator in Prism is a very simple class with only one method. I was surprised when I noticed that there was no lock around the null check and creation of a new type to add to the private _events collection. If two threads called GetEvent simultaneously for the same type (before it exists in _events) it looks like this would result in two entries in the collection. /// <summary> /// Gets the single instance of the event managed by this EventAggregator. Multiple calls to this method with the same <typeparamref name="TEventType"/> returns the same event instance. /// </summary> /// <typeparam name="TEventType">The type of event to get. This must inherit from <see cref="EventBase"/>.</typeparam> /// <returns>A singleton instance of an event object of type <typeparamref name="TEventType"/>.</returns> public TEventType GetEvent<TEventType>() where TEventType : EventBase { TEventType eventInstance = _events.FirstOrDefault(evt => evt.GetType() == typeof(TEventType)) as TEventType; if (eventInstance == null) { eventInstance = Activator.CreateInstance<TEventType>(); _events.Add(eventInstance); } return eventInstance; }

  • Use of where in multiple joins to remove rows - linq

    - by bergin
    hi, I have a table of orders. the status is on the soilorders which is joined to the orders. I only want to return orders where the joined soilorder does not have status "Removed". I had thought that join sso in db.SoilSamplingOrders on ord.order_id equals sso.order_id where sso.status.Equals("Removed")!=true but then no records are returned! thanks for any help (query below) var query = from ord in db.Orders join sso in db.SoilSamplingOrders on ord.order_id equals sso.order_id where sso.status.Equals("Removed")!=true join cust in db.Customers on ord.customer_id equals cust.customer_id select new Listing { assigned_to = sso.assigned_to, company = cust.company, order_id = ord.order_id, order_created = ord.order_created, customer_id = ord.customer_id, order_created_by_employ_id = ord.order_created_by_employ_id, first_farm_on_order = (from f in db.SoilSamplingSubJobs where f.order_id == ord.order_id select new ListingSubJob { first_farm_on_order = f.farm }). AsEnumerable().First().first_farm_on_order, total_fields = (from f in db.SoilSamplingSubJobs where f.order_id == ord.order_id select new { f.sssj_id }).AsEnumerable().Count(), total_area = (float?) (from f in db.SoilSamplingSubJobs where f.order_id == ord.order_id && f.area_ha != null select f.area_ha ).Sum() ?? 0 , total_area_ph_density = (float?)(from f in db.SoilSamplingSubJobs where f.order_id == ord.order_id && f.ph != null select f.ph).Sum() ?? 0, };
