I am trying to implement position-sensitive zooming inside a JScrollPane. The JScrollPane contains a component with a customized 'paint' that will draw itself inside whatever space it is allocated - so zooming is as easy as using a MouseWheelListener that resizes the inner component as required. But I also want zooming into (or out of) ...
Most modern apps provide an interactive way to push a long running operation onto a background queue. I am developing a swing application and I have implemented a simple "framework" to support that. However, I can't help but think that something like that must exist already. I have heard that Netbeans provides that, but I don't want to m...
If I'm deploying to servers with WebSphere 6.1 (Java 1.5), should I use IBM's JDK on my build box? Or will Sun's JDK compile to the same binary? If I should use IBM's, where can I get the Windows x64 version? ...

In Java you can give the number zero as a single parameter for the Socket or DatagramSocket constructor. Java binds that Socket to a free port then. Is it possible to limit the port lookup to a specific range? Thanks in advance, Roland ...
I recently asked a question about Oracle Encryption. Along the way to finding a solution for myself I decided to move the encryption (well, obfuscation) to the application side for certain tasks. My problem is that the database is already encrypting data a certain way and I need Java code to duplicate that functionality, so that text...

On the Windows machine there is a Java console running, where I want to send a Ctrl-Break so I can see the Java threads running.

Thanks. ...
I'm developing an application based on Eclipse's Rich Client Platform that relies heavily on the use of tables for showing and editing data. I'm currently using the SWT implementations of Table and TableViewer. My users are forever complaining that it "doesn't work like in excel". Most notably, I can't select a single cell within a row...
I am looking into an image processing problem for semi-real time detection of certain scenarios. My goal is to have the live video arrive as Motion JPEG frames in my Java code somehow. I am familiar with the Java Media Framework and, sadly, I think we can consider that an effectively dead API. I am also familiar with Axis boxes and,...
Hi, I'm getting an error message when I try to build my project in eclipse: The type weblogic.utils.expressions.ExpressionMap cannot be resolved. It is indirectly referenced from required .class files I've looked online for a solution and cannot find one (except for those sites that make you pay for help). Anyone have any idea of a...
Has anyone experienced issues with Java's default garbage collector while running apps on VmWare instances? I am experiencing issues where full garbage collections are not running as often as I would expect and am curious if the VmWare variable has anything to do with it. ...
Hi, I have a Jasper report template, and I need to show/hide a column at runtime based on a particular condition. I'm using "Print when expression" to conditionally show/hide this column (and it's header) in my report. When the column is hidden, the space it would have occupied is left blank, which is not particularly attractive. I wou...
Do you keep project files like Eclipse's .project, .classpath, .settings under version control (e.g. subversion)? ...
Some files in our repository are individual to each developer. For example some developers use a local database, which is configured in a properties file in the project. So each developer has different settings. When one developer commits, he always has to take care to not commit his individually configured files. How do you handle this...
I'm used to python, so this is a bit confusing to me. I'm trying to take in input, line-by-line, until a user inputs a certain number. The numbers will be stored in an array to apply some statistical maths to them. Currently, I have a main class, the stats classes, and an "reading" class. Two Questions: I can't seem to get the input l...
