  • How can I view javadocs that have been added to a maven repository?

    - by Coderer
    I know I can use maven to pull the javadocs for an artifact (if they've been added), which should come through as a JAR (right?), which I can then unpack and browse. My problem is, I'm trying to figure out which of a series of artifacts have the particular package I'm hunting for. I could download a half-dozen javadoc packages, unpack all of them, then open the index files one at a time, but that sounds like it would be pretty unpleasant. There must be a better way! I noticed that Nexus supports javadoc artifact browsing, but apparently only in the Pro version (which we do not have, and are unlikely to get any time soon). I'd prefer a GUI solution, though I'd settle for a command line answer, provided it's something along the lines of showmethedocs groupId:artifactId [version].

  • Where are the clever uses of strict evaluation?

    - by devonrt
    It seems like there are plenty of examples of clever things being done in a lazily-evaluated language that can't be done in an environment with strict evaluation. For example infinite lists in Haskell or replacing every element in a tree with the tree's minimum value in one pass. Are there any examples of clever things being done in a strictly-evaluated language that can't easily be done in a lazily-evaluated language?

  • Alter a function as a parameter before evaluating it?

    - by Shane
    Is there any way, given a function passed as a parameter, to alter its input parameter string before evaluating it? Here's pseudo-code for what I'm hoping to achieve: test.func <- function(a, b) { # here I want to alter the b expression before evaluating it: b(..., val1=a) } Given the function call passed to b, I want to add in a as another parameter without needing to always specify ... in the b call. So the output from this test.func call should be: test.func(a="a", b=paste(1, 2)) "1" "2" "a"

  • Alter a function as a parameter before evaluating it in R?

    - by Shane
    Is there any way, given a function passed as a parameter, to alter its input parameter string before evaluating it? Here's pseudo-code for what I'm hoping to achieve: test.func <- function(a, b) { # here I want to alter the b expression before evaluating it: b(..., val1=a) } Given the function call passed to b, I want to add in a as another parameter without needing to always specify ... in the b call. So the output from this test.func call should be: test.func(a="a", b=paste(1, 2)) "1" "2" "a" Edit: Another way I could see doing something like this would be if I could assign the additional parameter within the scope of the parent function (again, as pseudo-code); in this case a would be within the scope of t1 and hence t2, but not globally assigned: t2 <- function(...) { paste(a=a, ...) } t1 <- function(a, b) { local( { a <<- a; b } ) } t1(a="a", b=t2(1, 2)) This is somewhat akin to currying in that I'm nesting the parameter within the function itself. Edit 2: Just to add one more comment to this: I realize that one related approach could be to use "prototype-based programming" such that things would be inherited (which could be achieved with the proto package). But I was hoping for a easier way to simply alter the input parameters before evaluating in R.

  • Haskell: foldl' accumulator parameter

    - by Clinton
    I've been asking a few questions about strictness, but I think I've missed the mark before. Hopefully this is more precise. Lets say we have: n = 1000000 f z = foldl' (\(x1, x2) y -> (x1 + y, y - x2)) z [1..n] Without changing f, what should I set z = ... So that f z does not overflow the stack? (i.e. runs in constant space regardless of the size of n) Its okay if the answer requires GHC extensions. My first thought is to define: g (a1, a2) = (!a1, !a2) and then z = g (0, 0) But I don't think g is valid Haskell.

  • Recommendation for using equals in Entities and avoiding LazyInitializationExceptions?

    - by huxendupsel
    In the beginning there is a problem that wants to be solved. In my case i got an LazyInitializationException while using indexof in a Collection to retrieve an Object for manipulation. Here i start to think about using equals in EntityBeans (OR-Mapper at all). I know there are some discussions about overriding equals in association with OR-Mapper as hibernate like [1] Entities equals(), hashCode() and toString(). How to correctly implement them? [2] To equals and hashcode or not on entity classes, that is the question. [3] Overriding equals and hashCode in Java I currently have some entities which implements the equals but inside the code i could not use equals several times because of the LazyInitializationExceptions. So i had to workaround and use eg. the name property of the object to identify it's equality. From my point of view the whole 'LazyInitializationException-thing' is not really mentioned in this questions. I'd like to know have you got some good patterns or real live recommendations how to avoid such exception in an equal-Method. Shall i use some helper Methodes to distinguish if a Object of a class is already initialized (4) or should i apdicate the use of equals and use helper classes instead (2)? And what is about catching LazyInitializationExceptions in the equals? [Edit]: If you put equals in context with the initialization of the Object then it will gain importance. Sometimes it is nessesary to have the Object fully initialized but sometimes you don't want to. Because you just need the Object itself (name, id, ...) not its Collection-Properties. So just for equalization you have to reattach the Object and load the whole bunch you don't realy need? Are there any other solutions for such a problem?

  • VS 2010 debugger not loading symbols when attaching to NUnit

    - by Dave Hanna
    (I just posted this in the NUnit discussion group on groups.google.com) Under VS 2008, I would run my tests under NUnit, and, if I needed to debug, I would attach the VS2008 debugger to the running Nunit process (Debug - Attach to Process), and set any breakpoints on code I wanted to examine. When I hit the Run buttion in NUnit, it would hit the breakpoint. (BTW, if it matters, this was running NUnit 2.5.2). I just upgraded to NUnit 2.5.4 and VS 2010. When I set a breakpoint, then attach to NUnit, I get a little warning symbol on the breakpoint dot, and hovering over it gives the tooltip "Breakpoint will not be hit. No symbols are currently loaded". Going to the Debug - Windows - Modules window shows a whole bunch of Windows and NUnit modules loaded, with the Symbol Status of "Skipped loading symbols", and then 1 module with a funny name that changes each time (r1euhmh5 right now), and Symbol Status of "No symbols loaded". (There is no trace of a module with a name remotely like my DLL under test). Right clicking the funny filename (assuming that to be some mapping from my DLL under test), and clicking Load Symbols From - Symbol Path, and navigating to the bin\debug folder, then clicking the pdb file of my DLL under test, I get the message "A matching symbol was not found in this folder". (The top of the Open dialog box has a line that says "Original location: r1euhmh5.pdb") So what's changed? And how do I go about debugging/breakpointing under VS 2010/NUnit 2.5.4 (Or is it possible I screwed something up when I decided to go through my VS2010 options and set some of them to more advanced levels than I knew what I was doing?) I appreciate any help.

  • Crystal Reports Images not loading in ASP.NET MVC

    - by Ryan Shripat
    I'm using Crystal Reports in a Webform inside of an MVC application. Images in the reports are not being displayed, however, on both the ASP.NET Development Server and IIS 7 (on Win7x64). I know from a number of other questions similar to this that the CrystalImageHandler HTTP Handler is responsible for rendering the image, but I've tried all of the usual solutions to no avail. So far, I have Added the following to my appSettings (via http://www.mail-archive.com/[email protected]/msg26882.html) <add key="CrystalImageCleaner-AutoStart" value="true" /> <add key="CrystalImageCleaner-Sleep" value="60000" /> <add key="CrystalImageCleaner-Age" value="120000" /> Added the following httpHandler to system.web/httpHandlers (via http://stackoverflow.com/questions/2253682/crystal-report-viewer-control-isnt-loading-the-images-inside-the-report) <add verb="GET" path="CrystalImageHandler.aspx" type="CrystalDecisions.Web.CrystalImageHandler, CrystalDecisions.Web, Version=12.0.2000.0, Culture=neutral, PublicKeyToken=692fbea5521e1304"/> Added the following to my Global.asax.cs (via http://stackoverflow.com/questions/2006011/crystal-reports-images-and-asp-net-mvc) routes.IgnoreRoute("{resource}.aspx/{*pathInfo}"); and routes.IgnoreRoute("CrystalImageHandler.aspx"); Any ideas as to why the images still 404?

  • Loading JNI lib on OSX?

    - by Clinton
    Background So I am attempting to load a jnilib (specifically JOGL) into java on OSX at runtime. I have been following along the relevant stackoverflow questions: Maven and the JOGL Library Loading DLL in Java - Eclipse - JNI How to make a jar file that include all jar files The end goal for me is to package platform specific JOGL files into a jar and unzip them into a temp directory and load them at start-up. I worked my problem back to simply attempting to load JOGL using hard-coded paths: File f = new File("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl.jnilib"); System.load(f.toString()); f = new File ("/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/libjogl_awt.jnilib"); System.load(f.toString()); I get the following exception when attempting to use the JOGL API: Exception in thread "main" java.lang.UnsatisfiedLinkError: no jogl in java.library.path But when I specify java.library.path by adding the following JVM option: -Djava.library.path="/var/folders/+n/+nfb8NHsHiSpEh6AHMCyvE+++TI/-Tmp-/" Everything works fine. Question Is it possible use System.load (or some other variant) on OSX as a replacement for -Djava.library.path that is invoked at runtime?

  • QWebView not loading external resources

    - by Nick
    Hi. I'm working on a kiosk web browser using Qt and PyQt4. QWebView seems to work quite well except for one quirk. If a URL fails to load for any reason, I want to redirect the user to a custom error page. I've done this using the loadFinished() signal to check the result, and change the URL to the custom page if necessary using QWebView.load(). However, any page I attempt to load here fails to pull in external resources like CSS or images. Using QWebView.load() to set the initial page at startup seems to work fine, and clicking any link on the custom error page will result in the destination page loading fine. It's just the error page that doesn't work. I'm really not sure where to go next. I've included the source for an app that will replicate the problem below. It takes a URL as a command line argument - a valid URL will display correctly, a bad URL (eg. DNS resolution fails) will redirect to Google, but with the logo missing. import sys from PyQt4 import QtGui, QtCore, QtWebKit class MyWebView(QtWebKit.QWebView): def __init__(self, parent=None): QtWebKit.QWebView.__init__(self, parent) self.resize(800, 600) self.load(QtCore.QUrl(sys.argv[1])) self.connect(self, QtCore.SIGNAL('loadFinished(bool)'), self.checkLoadResult) def checkLoadResult(self, result): if (result == False): self.load(QtCore.QUrl('http://google.com')) app = QtGui.QApplication(sys.argv) main = MyWebView() main.show() sys.exit(app.exec_()) If anyone could offer some advice it would be greatly appreciated.

  • OutOfMemory exception when loading an image in .Net

    - by Ben
    Hi, Im loading an image from a SQL CE db and then trying to load that into a PictureBox. I am saving the image like this: if (ofd.ShowDialog() == DialogResult.OK) { picArtwork.ImageLocation = ofd.FileName; using (System.IO.FileStream fs = new System.IO.FileStream(ofd.FileName, System.IO.FileMode.Open)) { byte[] imageAsBytes = new byte[fs.Length]; fs.Read(imageAsBytes, 0, imageAsBytes.Length); thisItem.Artwork = imageAsBytes; fs.Close(); } } and then saving to the Db using LINQ To SQL. I load the image back like so: using (FileStream fs = new FileStream(@"C:\Temp\img.jpg", FileMode.CreateNew ,FileAccess.Write )) { byte[] img = (byte[])encoding.GetBytes(ThisFilm.Artwork.ToString()); fs.Write(img, 0, img.Length); } but am getting an OutOfMemoryException. I have read that this is a slight red herring and that there is probably something wrong with the filetype, but i cant figure what. Any ideas? Thanks picArtwork.Image = System.Drawing.Bitmap.FromFile(@"C:\Temp\img.jpg");

  • loading content from php file with jQuery

    - by Billa
    The following code fetch all data (by clicking a.info link) from a php file "info.php" and prints in the #content div. The problem is that it prints everything from info.php file. Can I possibly select only some part of data from info.php file to load in #content? The reason to ask this question is that, I want to load different data from the same php file for the different links. $("a.info").click(function(){ var id=$(this).attr("id"); $("#box").slideDown("slow"); $.ajax({ type: "POST", data: "id="+$(this).attr("id"), url: "info.php", success: function(html){ $("#content").html(html); } }); }); Html where content is loading: <div id="box"> <div id="content"></div> </div> info.php paragraph1. paragraph2. For example, In the above info.php file, i only want to load paragraph1 in the #content. I hope my question is clear. Any help will be appreciated.

  • Load Assembly in New AppDomain without loading it in Parent AppDomain

    - by Al Katawazi
    I am attempting to load a dll into a console app and then unload it and delete the file completely. The problem I am having is that the act of loading the dll in its own AppDomain creates a reference in the Parent AppDomain thus not allowing me to destroy the dll file unless I totally shut down the program. Any thoughts on making this code work? string fileLocation = @"C:\Collector.dll"; AppDomain domain = AppDomain.CreateDomain(fileLocation); domain.Load(@"Services.Collector"); AppDomain.Unload(domain); BTW I have also tried this code with no luck either string fileLocation = @"C:\Collector.dll"; byte[] assemblyFileBuffer = File.ReadAllBytes(fileLocation); AppDomainSetup domainSetup = new AppDomainSetup(); domainSetup.ApplicationBase = Environment.CurrentDirectory; domainSetup.ShadowCopyFiles = "true"; domainSetup.CachePath = Environment.CurrentDirectory; AppDomain tempAppDomain = AppDomain.CreateDomain("Services.Collector", AppDomain.CurrentDomain.Evidence, domainSetup); //Load up the temp assembly and do stuff Assembly projectAssembly = tempAppDomain.Load(assemblyFileBuffer); //Then I'm trying to clean up AppDomain.Unload(tempAppDomain); tempAppDomain = null; File.Delete(fileLocation);

  • Getting browser to make an AJAX call ASAP, while page is still loading

    - by Chris
    I'm looking for tips on how to get the browser to kick off an AJAX call as soon as possible into processing a web page, ideally before the page is fully downloaded. Here's my approximate motivation: I have a web page that takes, say, 5 seconds to load. It calls a web service that takes, say, 10 seconds to load. If loading the page and calling the web service happened sequentially, the user would have to wait 15 seconds to see all the information. However, if I can get the web service call started before the 5 second page load is complete, then at least some of the work can happened in parallel. Ideally I'd like as much of the work to happen in parallel as possible. My initial theory was that I should place the AJAX-calling javascript as high up as possible in the web page HTML source (being mindful of putting it after the jquery.js include, because I'm making the call using jquery ajax). I'm also being mindful not to wrap the AJAX call in a jquery ready event handler. (I mention this because ready events are popular in a lot of jquery example code.) However, the AJAX call still doesn't seem to get kicked off as early as I'm hoping (at least as judged by the Google Chrome "Timeline" feature), so I'm wondering what other considerations apply. One thing that might potentially be detrimental is that the AJAX call is back to the same web server that's serving the original web page, so I might be in danger of hitting a browser limit on the # of HTTP connections back to that one machine? (The HTML page loads a number of images, css files, etc..)

  • Loading a javascript library in javax.script?

    - by Shane
    I want to run Protovis javascript from Java and get the evaluated SVG code. I am using javax.script.* to run the Javascript: public static void EvalScript() throws Exception { ScriptEngineManager factory = new ScriptEngineManager(); ScriptEngine engine = factory.getEngineByName("JavaScript"); Object result = engine.eval("var vis = new pv.Panel().width(300).height(300) .add (pv.Line).data ([1,0.5, 0.1, 0.01, 0.001, 0.3, 0.2,0.1,1]) .left (function () { return this.index * 30; }) .bottom (function (d) { return d * 250; }); vis.root.render(); vis.scene[0].canvas.innerHTML;"); System.out.println(result); } This would complain because I never loaded Protovis itself, as would ordinarily be done with <script type="text/javascript" src="../protovis-r3.1.0.js"></script> Is there a good way, short of sourcing in the full Javascript into the eval() command, of loading a library when running Javascript through javax.script? (Incidentally, I know of examples that use Rhino to do this from the Google discussion group.)

  • Asynchronous Image loading in certain custom UITableViewCells

    - by Dan
    So, I'm sure that this issue has been brought up before, but I haven't quite seen a solution for my specific problem. What I'm doing is loading a group of custom UITableViewCell's that are drawn using Loren Brichter's solution, each cell has some content, an icon (representing the user) that is asynchronously loaded into it, and a few other things. Eventually, I'm hoping to add support for images. Not every cell has an image, so in the creation of the cell, it determines if an image is required to be loaded and drawn into the cell. My problem is that I don't know how I can do that while keeping the image loaded asynchronously - with not every cell having the need to load an image (like needed with the icon) I'm not sure how to keep it in order when an cell is thrown off screen and re-rendered when the user scrolls over it. Each cell draws it content from an NSArray containing a custom object called FeedItem. All I'm really looking for is some sort of solution or idea to help me because right now I am at a loss. Thanks guys, I will appreciate the help.

  • Custom view with nib as subview doesn't seem to be loading

    - by Ben Collins
    I've created a custom view that loads its content from a nib, like this: /* PricingDataView.h */ #import <UIKit/UIKIt.h> @interface PricingDataView : UIView { UIView *contentView; } @property (nonatomic, retain) IBOutlet UIView *contentView; @end /* PricingDataView.m */ #import "PricingDataView.h" @implementation PricingDataView @synthesize contentView; - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { [[NSBundle mainBundle] loadNibNamed:@"PricingDataView" owner:self options:nil]; [contentView setFrame:frame]; [self addSubview:contentView]; } return self; } /* ... */ In the nib file I set PricingDataView as the type of the File's Owner, and connected the contentView outlet in IB. I placed a regular UIView from the Interface Library onto the full-sized view shown to the user, and then changed it's class name to PricingDataView. It all builds, but at runtime, nothing is rendered where my custom view is supposed to be. I put breakpoints in PricingDataView.initWithFrame, but they don't hit, so I know I'm missing something that would cause the view to be initialized. What I'm curious about is that int the process of loading my other views from nibs, all the initialization happens for me, but not with this one. Why?

  • Loading animation Memory leak

    - by Ayaz Alavi
    Hi, I have written network class that is managing all network calls for my application. There are two methods showLoadingAnimationView and hideLoadingAnimationView that will show UIActivityIndicatorView in a view over my current viewcontroller with fade background. I am getting memory leaks somewhere on these two methods. Here is the code -(void)showLoadingAnimationView { textmeAppDelegate *textme = (textmeAppDelegate *)[[UIApplication sharedApplication] delegate]; [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; if(wrapperLoading != nil) { [wrapperLoading release]; } wrapperLoading = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; wrapperLoading.backgroundColor = [UIColor clearColor]; wrapperLoading.alpha = 0.8; UIView *_loadingBG = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 320.0, 480.0)]; _loadingBG.backgroundColor = [UIColor blackColor]; _loadingBG.alpha = 0.4; circlingWheel = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; CGRect wheelFrame = circlingWheel.frame; circlingWheel.frame = CGRectMake(((320.0 - wheelFrame.size.width) / 2.0), ((480.0 - wheelFrame.size.height) / 2.0), wheelFrame.size.width, wheelFrame.size.height); [wrapperLoading addSubview:_loadingBG]; [wrapperLoading addSubview:circlingWheel]; [circlingWheel startAnimating]; [textme.window addSubview:wrapperLoading]; [_loadingBG release]; [circlingWheel release]; } -(void)hideLoadingAnimationView { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; wrapperLoading.alpha = 0.0; [self.wrapperLoading removeFromSuperview]; //[NSTimer scheduledTimerWithTimeInterval:0.8 target:wrapperLoading selector:@selector(removeFromSuperview) userInfo:nil repeats:NO]; } Here is how I am calling these two methods [NSThread detachNewThreadSelector:@selector(showLoadingAnimationView) toTarget:self withObject:nil]; and then somewhere later in the code i am using following function call to hide animation. [self hideLoadingAnimationView]; I am getting memory leaks when I call showLoadingAnimationView function. Anything wrong in the code or is there any better technique to show loading animation when we do network calls?

  • Load Ruby on Rails models without loading the entire framework

    - by epochwolf
    I'm looking to create a custom daemon that will run various database tasks such as delaying mailings and user notifications (each notice is a separate row in the notifications table). I don't want to use script/runner or rake to do these tasks because it is possible that some of the tasks only require the create of one or two database rows or thousands of rows depending on the task. I don't want the overhead of launching a ruby process or loading the entire rails framework for each operation. I plan to keep this daemon in memory full time. To create this daemon I would like to use my models from my ruby on rails application. I have a number of rails plugins such as acts_as_tree and AASM that I will need loaded if I where to use the models. Some of the plugins I need to load are custom hacks on ActiveRecord::Base that I've created. (I am willing to accept removing or recoding some of the plugins if they need components from other parts of rails.) My questions are Is this a good idea? And - Is this possible to do in a way that doesn't have me manually including each file in my models and plugins? If not a good idea What is a good alternative? (I am not apposed to doing writing my own SQL queries but I would have to add database constraints and a separate user for the daemon to prevent any stupid accidents. Given my lack of familiarity with configuring a database, I would like to use active record as a crutch.)

Here is my loader code public var preLoader:Loader; preLoader=new Loader(); **update** Security.loadPolicyFile('http://api.facebook.com/crossdomain.xml'); Security.allowDomain('http://profile.ak.fbcdn.net'); Security.allowInsecureDomain('http://profile.ak.fbcdn.net'); **update-end** public function imageContainer(Imagewidth:Number,Imageheight:Number,url:String,path:String) { preLoader=new Loader(); Security.loadPolicyFile("http://api.facebook.com/crossdomain.xml"); var context:LoaderContext = new LoaderContext(); context.checkPolicyFile = true; context.applicationDomain = ApplicationDomain.currentDomain; preLoader.load(new URLRequest(path),context); Any Ideas? I am importing the right class though. UPDATE: I am loading the images from a different domain say , calling func http://fahim.com images are from http://profile.ak.fbcdn.net/v22941/254/15/q652310588_2173.jpg something ( I have made sure the pictures are static do not require a facebook login or anything , they are just user public profile pictures)

  • Loading a UITableView From A Nib

    - by Garry
    Hi, I keep getting a crash when loading a UITableView. I am trying to use a cell defined in a nib file. I have an IBOutlet defined in the view controller header file: UITableViewCell *jobCell; @property (nonatomic, assign) IBOutlet UITableViewCell *jobCell; This is synthesised in the implementation file. I have a UITableViewCell created in IB and set it's identifier to JobCell. Here is the cellForRowAtIndexPath method: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellIdentifier = @"JobCell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"JobsRootViewController" owner:self options:nil]; cell = jobCell; self.jobCell = nil; } // Get this job Job *job = [fetchedResultsController objectAtIndexPath:indexPath]; // Job title UILabel *jobTitle; jobTitle = (UILabel *)[cell viewWithTag:tagJobTitle]; jobTitle.text = job.title; // Job due date UILabel *dueDate; dueDate = (UILabel *)[cell viewWithTag:tagJobDueDate]; dueDate.text = [self.dateFormatter stringFromDate:job.dueDate]; // Notes icon UIImageView *notesImageView; notesImageView = (UIImageView *)[cell viewWithTag:tagNotesImageView]; if ([job.notes length] > 0) { // This job has a note attached to it - show the notes icon notesImageView.hidden = NO; } else { // Hide the notes icon notesImageView.hidden = YES; } // Job completed button // Return the cell return cell; } When I run the app - I get a hard crash and the console reports the following: objc[1291]: FREED(id): message style sent to freed object=0x4046400 I have hooked up all the outlets in IB correctly. What is the issue? Thanks,
