  • Exception thrown while working with JTabbedPane

    - by Halo
    I'm using a JTabbedPane in my application and I listen to its changes with ChangeListener so that I can know which tab is currently selected. So my stateChanged method is; public void stateChanged(ChangeEvent e) { currentPageIndex = jTabbedPane.getSelectedIndex(); } But while I'm adding new tabs to the JTabbedPane it throws an ArrayIndexOutOfBoundsException in the method above, I don't know why. Some suggested for a similar case that this is a bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4873983, but as you'll see some says the solution is to work with Swing from EventDispatchThread. What does it mean, do they mean the SwingUtilities.invokeLater thing? Can someone show me how I can modify my stateChanged method accordingly to avoid the exception?

  • Am I correct in my assumption about synchronized block?

    - by kunjaan
    I have a method shout() with a synchronized block. private void shout(){ System.out.println("SHOUT " + Thread.currentThread().getName()); synchronized(this){ System.out.println("Synchronized Shout" + Thread.currentThread().getName()); try { Thread.sleep(50); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("Synchronized Shout" + Thread.currentThread().getName()); } } If I have two Threads that run this method, am I correct in assuming that the two "Synchronized Shout" will always appear one after the other? There can be no other statements in between the "Synchronized Shout"?

  • Focused animation on custom JDialog

    - by n002213f
    If a JFrame has a JDialog modal open, the JDialog is animated (the borders and title bar have a lighter colour) if any other part of the application is clicked other than the JDialog with focus. The user is made aware of the window in focus to attend to first. I have a Swing application with custom dialogs, setUndecorated(true) and custom title bars. Is it possible to implement the behaviour described above for these custome dialogs?

  • Powermock Slows Down Test Startup on Eclipse/Fedora 10 when on NTFS partition

    - by MrWiggles
    I've just started having a proper play with Powermock and noticed that it slows down test startup immensely. A quick look at top while it was running shows that mount.nfts-3g was taking up most of the CPU. I moved Eclipse and my source directory to ext3 partitions to see if that was a problem and the tests now startup quicker but there's still a noticeable delay. Is this normal with Powermock or am I missing something obvious?

  • JPA @ManyToMany on only one side?

    - by Ethan Leroy
    I am trying to refresh the @ManyToMany relation but it gets cleared instead... My Project class looks like this: @Entity public class Project { ... @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER) @JoinTable(name = "PROJECT_USER", joinColumns = @JoinColumn(name = "PROJECT_ID", referencedColumnName = "ID"), inverseJoinColumns = @JoinColumn(name = "USER_ID", referencedColumnName = "ID")) private Collection<User> users; ... } But I don't have - and I don't want - the collection of Projects in the User entity. When I look at the generated database tables, they look good. They contain all columns and constraints (primary/foreign keys). But when I persist a Project that has a list of Users (and the users are still in the database), the mapping table doesn't get updated gets updated but when I refresh the project afterwards, the list of Users is cleared. For better understanding: Project project = ...; // new project with users that are available in the db System.out.println(project getUsers().size()); // prints 5 em.persist(project); System.out.println(project getUsers().size()); // prints 5 em.refresh(project); System.out.println(project getUsers().size()); // prints 0 So, how can I refresh the relation between User and Project?

  • Android - Correspondence between ImageView coordinates and Bitmap Pixels

    - by Matteo
    In my application I want the user to be able to select some content of an Image contained inside an ImageView. To select the content I subclassed the ImageView class making it implement the OnTouchListener so to draw over it a rectangle with borders decided by the user. Here is an example of the result of the drawing (to have an idea you can think of it as when you click with the mouse on your desktop and drag the mouse): Now I need to determine which pixels of the Bitmap image correspond to the selected part. It's kind of easy to determine which are the points of the ImageView belonging to the rectangle, but I don't know how to get the correspondent pixels, since the ImageView has a different aspect ratio than the original image. I followed the approach described especially here, but also here, but am not fully satisfied because in my opinion the correspondence made is 1 on 1 between pixels and points on the ImageView and does not give me all the correspondent pixels on the original image to the selected area. Calling hoveredRect the rectangle on the ImageView the points inside of it are: class Point { float x, y; @Override public String toString() { return x + ", " + y; } } Vector<Point> pointsInRect = new Vector<Point>(); for( int x = hoveredRect.left; x <= hoveredRect.right; x++ ){ for( int y = hoveredRect.top; y <= hoveredRect.bottom; y++ ){ Point pointInRect = new Point(); pointInRect.x = x; pointInRect.y = y; pointsInRect.add(pointInRect); } } How can I obtain a Vector<Pixels> pixelsInImage containing the correspondent pixels?

  • Group Chat XMPP with Google App Engine

    - by David Shellabarger
    Google App Engine has a great XMPP service built in. One of the few limitations it has is that it doesn't support receiving messages from a group chat. That's the one thing I want to do with it. :( Can I run a 3rd party XMPP/Jabber server on App Engine that supports group chat? If so, which one?

  • HttpURLConnection: What's the deal with having to read the whole response?

    - by stormin986
    My current problem is very similar to this one. I have a downloadFile(URL) function that creates a new HttpURLConnection, opens it, reads it, returns the results. When I call this function on the same URL multiple times, the second time around it almost always returns a response code of -1 (But throws no exception!!!). The top answer in that question is very helpful, but there are a few things I'm trying to understand. So, if setting http.keepAlive to false solves the problem, it indicates what exactly? That the server is responding in a way that violates the http protocol? Or more likely, my code is violating the protocol in some way? What will the trace tell me? What should I look for? And what's the deal with this: You need to read everything from error stream. Otherwise, it's going to confuse next connection and that's the cause of -1. Does this mean if the response is some type of error (which would be what response code(s)?), the stream HAS to be fully read? Also, every time I am attempting an http request I am basically creating a new connection, and then disconnect()ing it at the end. However, in my case I'm not getting a 401 or whatever. It's always a 200. But my second connection almost always fails. Does this mean there's some other data I should be reading that I'm not (in a similar manner that the error stream must be fully read)? Please help shed some light on this? I feel like there's some fundamental http protocol understanding I'm missing.

  • Spring and hibernate.cfg.xml

    - by Steve Kuo
    How do I get Spring to load Hibernate's properties from hibernate.cfg.xml? We're using Spring and JPA (with Hibernate as the implementation). Spring's applicationContext.xml specifies the JPA dialect and Hibernate properties: <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="jpaDialect"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" /> </property> <property name="jpaProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLInnoDBDialect</prop> </props> </property> </bean> In this configuration, Spring is reading all the Hibernate properties via applicationContext.xml . When I create a hibernate.cfg.xml (located at the root of my classpath, the same level as META-INF), Hibernate doesn't read it at all (it's completely ignored). What I'm trying to do is configure Hibernate second level cache by inserting the cache properties in hibernate.cfg.xml: <cache usage="transactional|read-write|nonstrict-read-write|read-only" region="RegionName" include="all|non-lazy" />

  • Simple HTTP Framework and time issue

    - by Deniz Acay
    I'm using Simple Framework for my recent project, and there is a problem with the date headers generated by the system. I can get my local time from Date class correctly, but setDate method of Simple's Response class sets date in milliseconds and when i do that by calling System.currentTimeInMillis, dates in response headers are incorrect. is there any way to solve this problem with Simple Framework? If not, what can i do except calling set method with a date string? Thanks in advance... EDIT: Date in the headers are in wrong timezone. And i also tried Calendar.getInstance().getTimeInMilis() method.

  • If it is possible to auto-format code before and after a source control commit, checkout, diff, etc.

    - by dennisjtaylor
    If it is possible to auto-format code before and after a source control commit, checkout, diff, etc. does a company really need a standard code style? It feels like standard coding style debates that have been raging since programming began like "put the bracket on the following line" or "properly indent your (" are no longer essential. I realize in languages where white space matters the diff will have to consider it but for languages where the style is a personal preference is there really a need to worry about it anymore?

  • How to get size of bytes?

    - by k80sg
    How do I obtain the number of bytes before allocating the byte size of the array 'handsize' as shown below as the incoming ByteArray data are sent in 3 different sizes. Thanks. BufferedInputStream bais = new BufferedInputStream(requestSocket.getInputStream()); DataInputStream datainput = new DataInputStream(bais); //need to read the number of bytes here before proceeding. byte[] handsize = new byte[bytesize]; datainput.readFully(handsize);

  • Why empty String is treated as null in oracle?

    - by GK
    We are using empty string in DB2 database for some business logic. but when the same record tried to insert into the Oracle it throws some not null property references to null value error. that is oracle treats empty string as null. So i am wondering why it is like that. and if there is a requirement of storing empty string how to do that on oracle?

  • Specifying distinct sequence per table in Hibernate on subclasses

    - by gutch
    Is there a way to specify distinct sequences for each table in Hibernate, if the ID is defined on a mapped superclass? All entities in our application extend a superclass called DataObject like this: @MappedSuperclass public abstract class DataObject implements Serializable { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) @Column(name = "id") private int id; } @Entity @Table(name = "entity_a") public class EntityA extends DataObject { ... } @Entity @Table(name = "entity_b") public class EntityB extends DataObject { ... } This causes all entities to use a shared sequence, the default hibernate_sequence. What I would like to do is use a separate sequence for each entity, for example entity_a_sequence and entity_b_sequence in the example above. If the ID were specified on the subclasses then I could use the @SequenceGenerator annotation to specify a sequence for each entity, but in this case the ID is on the superclass. Given that ID is in the superclass, is there a way I can use a separate sequence for each entity — and if so, how? (We are using PostgreSQL 8.3, in case that's relevant)

  • Issue with multipart upload in servlet on seam

    - by stacker
    I created a servlet wich works fine when deployed in a separate war file, but I intend to use it as part of a seam application. I use commons-fileupload but the iterator (see snippet) returns false (only when included in the seam-app). Any ideas? protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { try { String action = request.getParameter( "action" ); if ( ServletFileUpload.isMultipartContent( request ) ) { log.info( "MULTIPART" ); } ServletFileUpload upload = new ServletFileUpload(); FileItemIterator iter = upload.getItemIterator( request ); // --------- hasNext() returns false, only in seam ----------- while ( iter.hasNext() ) { ...... } Additional Info: I don't want to use the technique described here since the uploading client is curl. The HttpServletRequest is wrapped by org.jboss.seam.web.IdentityRequestWrapper Using the seam

  • How to make Spring accept fluent (non-void) setters?

    - by Chris
    Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One") .setProperty2("Two") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris
