  • Can't run jUnit with Eclipse

    - by KimKha
    I use new Eclipse. Create demo test with jUnit (I added default jUnit library built-in Eclipse). Then I write this code: import junit.framework.*; import org.junit.Test; public class SimpleTest extends TestCase { public SimpleTest(String name) { super(name); } public final void main(String method){ } @Test public final void testSimpleTest() { int answer = 2; assertEquals((1+1), answer); } } But it doesn't run. In the Debug tab: org.eclipse.jdt.internal.junit.runner.RemoteTestRunner at localhost:52754 Thread [main] (Suspended (exception ClassNotFoundException)) URLClassLoader$1.run() line: not available [local variables unavailable] AccessController.doPrivileged(PrivilegedExceptionAction<T>, AccessControlContext) line: not available [native method] Launcher$AppClassLoader(URLClassLoader).findClass(String) line: not available Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: not available Launcher$AppClassLoader.loadClass(String, boolean) line: not available Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available How can I solve this?

  • How do I access a asp.net session variable from APP_CODE??

    - by user313714
    I have seen lots of posts here and elsewhere stating that one can access session variables from app_code. I want to access an already created session. this code errors out because of a null exception. string myFile = HttpContext.Current.Session["UploadedFile"]; this creates a null session variable. System.Web.SessionState.HttpSessionState Session = HttpContext.Current.Session; It looks like I can create a new session variable but not access an already created one. Anyone have any idea what might be giving me problems?

  • Group by/count in LINQ against SQL Compact 3.5 SP2

    - by bash74
    Hello, I am using LINQ-To-Entities in C# and run queries against a SQL Compact Server 3.5 SP2. What I try to achieve is a simple group by with an additional where clause which includes a Count(). var baseIdent="expression"; var found=from o in ObservedElements where o.ObservedRoots.BaseIdent==baseIdent group o by o.ID into grouped where grouped.Count()==1 select new {key=grouped.Key, val=grouped}; foreach(var res in found){ //do something here } This query throws the famous exception "A parameter is not allowed in this location. Ensure that the '@' sign and all other parameters are in a valid location in the SQL statement." When I either omit the where clause OR directly enter the expression "expression" in the query (where o.ObservedRoots.BaseIdent=="expression") everything just works fine. Does anybody know how to solve this? Workaround would also be fine? Thanks in advance, Sebastian

  • Arraylist is null; I cannot access books in the arraylist

    - by user3701380
    I am a beginner-intermediate java programmer and I am getting a null pointer exception from my arraylist. I am writing a bookstore program for APCS and when i add the book, it is supposed to add to the arraylist in the inventory class. But when i call a method to search for a book (e.g. by title), it shows that there isn't anything in the arraylist. //Here is my inventory class -- it has all methods for adding the book or searching for one The searching methods are in getBookByTitle, getBookByAuthor, and getBookByISBN and the method for adding a book is addBook package webbazonab; //Inventory Class //Bharath Senthil //Ansh Sikka import java.util.ArrayList; public class Inventory{ private ArrayList<Book> allBooks = new ArrayList<Book>(); private String bookTitles; private String bookAuthors; private String bookPrices; private String bookCopies; private String ISBNs; public Inventory() { } //@param double price, int copies, String bookTitle, String Author, String isbnNumber public void addBooks(Book addedBook){ allBooks.add(addedBook); } public boolean isAvailable(){ for(Book myBook : allBooks){ if(myBook.copiesLeft() == 0) return false; } return true; } public String populateTitle(){ for (Book titleBooks : allBooks){ bookTitles = titleBooks.getTitle() + "\n"; return bookTitles; } return bookTitles; } public String populateAuthor(){ for(Book authorBooks : allBooks){ bookAuthors = authorBooks.getAuthor() + "\n"; return bookAuthors; } return bookAuthors; } public String populatePrice(){ for (Book pricedBooks : allBooks){ bookPrices = String.valueOf(pricedBooks.getPrice()) + "\n"; } return "$" + bookPrices; } /** * * @return */ public String populateCopies(){ for (Book amtBooks : allBooks){ bookCopies = String.valueOf(amtBooks.copiesLeft()) + "\n"; return bookCopies; } return bookCopies; } public String populateISBN(){ for (Book isbnNums : allBooks){ ISBNs = isbnNums.getIsbn() + "\n"; return ISBNs; } return ISBNs; } @SuppressWarnings("empty-statement") public Book getBookByTitle(String titleSearch) { for(Book titleBook : allBooks) { if (titleBook.getTitle().equals(titleSearch)) { return titleBook; } } return null; } public Book getBookByISBN(String isbnSearch){ for(Book isbnBookSearches : allBooks){ if(isbnBookSearches.getIsbn().equals(isbnSearch)){ return isbnBookSearches; } } return null; } public Book getBookByAuthor(String authorSearch){ for(Book authorBookSearches : allBooks){ if(authorBookSearches.getAuthor().equals(authorSearch)){ return authorBookSearches; } } return null; } public void sort(){ for(int i = 0; i < allBooks.size(); i++) { for(int k = 0; k < allBooks.size(); k++) { if(((Book) allBooks.get(i)).getIsbn().compareTo(((Book) allBooks.get(k)).getIsbn()) < 1) { Book temp = (Book) allBooks.get(k); allBooks.set(k, allBooks.get(i)); allBooks.set(i, temp); } else if(((Book) allBooks.get(i)).getIsbn().compareTo(((Book) allBooks.get(k)).getIsbn()) > 1) { Book temp = (Book) allBooks.get(i); allBooks.set(i, allBooks.get(k)); allBooks.set(k, temp); } } } } public ArrayList<Book> getBooks(){ return allBooks; } } //The exception occurs when i call the method here (in another class): Inventory lib = new Inventory(); jTextField12.setText(lib.getBookByAuthor(authorSearch).getTitle()); Here is my book class if you need it package webbazonab; //Webbazon AB //Project By: Ansh Sikka and Bharath Senthil public class Book { private double myPrice; private String myTitle; private String bookAuthor; private String isbn; private int myCopies; public Book(double price, int copies, String bookTitle, String Author, String isbnNumber) { myPrice = price; myCopies = copies; myTitle = bookTitle; bookAuthor = Author; isbn = isbnNumber; } public double getPrice() { return myPrice; } public String getIsbn() { return isbn; } public String getTitle() { return myTitle; } public String getAuthor() { return bookAuthor; } public int copiesLeft(){ return myCopies; } public String notFound(){ return "The book you searched for could not be found!"; } public String toString() { return "Title: " + getTitle() + "\nAuthor: " + getAuthor() + "\nNumber of Available Books: " + copiesLeft() + "\nPrice: $" + getPrice(); } } Thanks!

  • Template error with django-photologue: 'Permission Denied'

    - by Ellie P.
    I'm in the process of re-setting up my Django development environment after reinstalling my OS. We use django-photologue with our project, which I installed using easy_install. However, I'm getting a template error on every template that has a photologue photo: TemplateSyntaxError at /newsroom/news/ Caught an exception while rendering: (13, 'Permission denied') One example of the line where the error is located: <img src="{{ photo.get_list_url }}"> I'm totally stumped--I've used photologue for this project on many different platforms and have never had this problem. Google yields nothing. I'm currently using Jolicloud (based on Ubuntu Jaunty). I'm working with a pre-existing database, so all of the photo sizes and everything have already been set up.

  • commons-exec: Executing a program on the system PATH?

    - by Stefan Kendall
    I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable (C:\Program files\...) then this code works. If I don't do this, I get an exception thrown with exit value 4. How do I get commons-exec to recognize the system path?

  • FreeLibrary vs implicit unloading DLL

    - by Adil
    I have implemented a DLL including DllMain() entry function:- BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { case DLL_PROCESS_ATTACH: ... case DLL_THREAD_ATTACH: ... case DLL_THREAD_DETACH: ... case DLL_PROCESS_DETACH: ... } Unfortunately i made a mistake in DLL_PROCESS_DETACH case and accessing illegal memorey (access violation). I made a sample program which loads the library using LoadLibrary() function, uses the library function and finally call FreeLibrary() and return. When i executed this program, i didnt get any error message. But if i remove FreeLibrary(), in that case the DLL_PROCESS_DETACH case is executed implicitly and this time it gives error dialog box mentioning that there is access violation. Why calling FreeLibrary() suppress this error? OR internally it handles this exception? What is suggested way.

  • How to retrieve stored reference to an NSManagedObject subclass?

    - by DavidDev
    Hi! I have a NSManagedObject subclass named Tour. I stored the reference to it using this code: prefs = [NSUserDefaults standardUserDefaults]; NSURL *myURL = [[myTour objectID] URIRepresentation]; NSData *uriData = [NSKeyedArchiver archivedDataWithRootObject:myURL]; [prefs setObject:uriData forKey:@"tour"]; Now I want to retrieve it. I tried using: NSData *myData = [prefs objectForKey:@"tour"]; NSURL *myURL = [NSKeyedUnarchiver unarchiveObjectWithData:myData]; TourAppDelegate *appDelegate = (TourAppDelegate *)[[UIApplication sharedApplication] delegate]; NSManagedObjectID *myID = [appDelegate.persistentStoreCoordinator managedObjectIDForURIRepresentation:myURL]; if (myID) { Tour *tempObject = [appDelegate.managedObjectContext objectWithID:myID]; //WARNING tour = tempObject; } if (tour) //instruction... But it's giving me this warning "Incompatible Objective-c types. Initializing 'struct NSManagedObject *', expected 'struct Tour *' Plus, when executing, it's giving me this: Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x5001eb0 How can I solve this?

  • C# getting version of unmanaged dll

    - by Richard
    I'm calling an unmanaged dll from my managed c# code and wanted to check I'm calling the right version. The code I'm trying to load the assembly (to then get the resource file and then get the version) is: cur_version = Assembly.LoadFile("X:\Workspace\yreceipts_pos\yRprintProcessor\Debug\yRprintProcessor.dll"); It's failing because of this error: The module was expected to contain an assembly manifest. (Exception from HRESULT: 0x80131018) Does anyone know how to get around this or have a better way to check the version of an unmanaged dll from managed c# code? Thanks in advance, Richard

  • Program skips code after trying to parse XML in VB.NET

    - by Bead
    I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break. I tried catching exception but none are occurring, so I'm not sure what the problem is. Here is my code: Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream()) Dim xDoc As XmlDocument = New XmlDocument() xDoc.LoadXml(reader.ReadToEnd()) Dim omfg As String = xDoc.ChildNodes().Item(0).InnerText() Dim name As XmlNodeList = xDoc.GetElementsByTagName("div") Dim jj As Integer = name.Count For i As Integer = 0 To name.Count - 1 MessageBox.Show(name.Item(i).InnerText) Next i Anything after the "xDoc.LoadXml(reader.ReadToEnd())" doesn't execute.. Any ideas on this? My XML does have some whitespace at the beginning, I don't know if that is causing the problem...

  • jQuery 1.4.x and the @ symbol

    - by David
    I used to use this script for jquery email obfuscation: $(".replaceAt").replaceWith("@"); $(".obfuscate").each(function () { $(this).attr("href", "mailto:"+$(this).text()); }); <a class="obfuscate">name<span class="replaceAt">-AT-</span>server.com</a> But with jQuery 1.4.x, I now get this error: uncaught exception: Syntax error, unrecognized expression: @ Looking this up on the net, it looks like jQuery thinks that the @ is a special character. I tried to "\@" it and a few other things with not luck. I'm not enough of a jQuery ninja to know how to fix this. Any ideas?

  • SL4: Root element is missing

    Hello, I know this has been asked elsewhere, but none of the questions or answers helped. I open an xml file in my SL 4 app: StreamResouceInfo sri = Application.GetResourceStream(new System.Uri("z.xml", UriKind.Relative)); if (null != sri) { XDocument xDoc = XDocument.Load(sri.Stream); } "Root element is missing" exception. The xml: Hmm, can't seem to post the xml... It is well-formed and valid, with a single root node and all tags closed. Thanks for any hints...

  • Does JavaME and/or Proguard reorder assignments?

    - by chrisdew
    This is a simplified example - I have two threads: Can JavaME and/Proguard ever reorder the obX = ... statements, such that thread_B will have a null pointer exception at ob2.someMethod? thread_A: Object ob1 = null; Object ob2 = null; ... ob1 = something1; ob2 = something2; thread_B: if (ob2 != null) { ob1.someMethod(); ... } P.S. I do realise that synchronising these will avoid the issue. Synchronisation has both a performance overhead, and more importantly, a chance to introduce deadlock.

  • OutOfMemoryError calling XmlSerializer.Deserialize() - not related to XML size!

    - by Mike Atlas
    This is a really crazy bug. The following is throwing an OutOfMemoryException, for XML snippits that are very short (e.g., <ABC def='123'/>) of one type, but not for others of the same size but a different type: (e.g., <ZYX qpr='baz'/>). public static T DeserializeXmlNode<T>(XmlNode node) { try { return (T)new XmlSerializer(typeof(T)) .Deserialize(new XmlNodeReader(node)); } catch (Exception ex) { throw; // just for catching a breakpoint. } } I read in this MSDN article that if I were using XmlSerializer with additional parameters in the constructor, I'd end up generating un-cached serializer assemblies every it got called, causing an Assembly Leak. But I'm not using additional parameters in the constructor. It also happens on the first call, too, so the AppDomain is fresh. Worse yet, it is only thrown in release builds, not debug builds. What gives?

  • Lightweight jQuery ColorPicker bound to input and with popup selector

    - by Scott B
    I've found two jQuery colorpickers that I'm considering using in my app. I have a simple input field that I'm asking users to supply a hex color to. I'd like to use jPicker's "Binded" example, however, the overall size of the jPicker is a bit more than I'd like to add to my app. So that sent me searching and I found a very nifty little compact picker called "Farbtastic", which does exactly what I want with one major exception: It appears to be an inline only solution (meaning, I can't call it in the same manner as jPicker's binded example. Can someone tell me how I might convert Farbtastic to mimic jPicker's binded example? More specifically, I'm looking to place a colorpicker widget (the small color frame icon as in the jPicker example) next to my input field so that it displays the currently selected color, and when clicked, it opens up the color palette widget.

  • cakephp - try/catch an Action

    - by joshs
    I would like to somehow apply a try catch statement to all Actions as a backstop for any uncaught exceptions. I think this would be particularly helpful for Ajax Actions, because the catch statement could send back a default 4xx status code. Prototype's onFailure() function could then do the client-side error handling. How can I do this without wrapping the Action call with a try/catch in the cake dispatcher like this: try { output = $controller->dispatchMethod($params['action'], $params['pass']); } catch {...} Does anybody have a suggestion or another workable strategy for gaining this functionality without touching the dispatcher? How do people feel about putting exception handling in the Displatcher? I imagine when cake drops php 4 support, there will be a built-in mechanism for this.

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?

Any solutions other than re-installing eclipse or creating a new workspace? I am using Axis2 1.4.1 and eclipse.

  • Database error when deleting entry in my rails app.

  • What is the correct way to unit test areas around exceptions

    - by Codek
    Hi, Looking at our code coverage of our unit tests we're quite high. But the last few % is tricky because a lot of them are catching things like database exceptions - which in normal circumstances just dont happen. For example the code prevents fields being too long etc, so the only possible database exceptions are if the DB is broken/down, or if the schema is changed under our feet. So is the only way to Mock the objects such that the exception can be thrown? That seems a little bit pointless. Perhaps it's better to just accept not getting 100% code coverage? Thanks, Dan
