For a quick demonstrator I'm looking for a SWT or Swing component which can display geographical data. Unfortunatly I'm disconnected from the internet, so Google Maps won't help. The general idea is to assemble a small eclipse RCP application with just 'map view', connect to a custom web service, that provides geographical data (tracks)...

I'm using Apache and Tomcat on a Windows server and since this morning, Tomcat stops working without any logs. It doesn't hang, it just shut down. There's no log in Tomcat, the CPU/Memory are fines, there are no System.Exit in my code. Anybody ever had this problem? It happens at random, after 5-10 minutes. The application responds no...

We have a huge code base and we suspect that there are quite a few "+" based string concats in the code that might benefit from the use of StringBuilder/StringBuffer. Is there an effective way or existing tools to search for these, especially in Eclipse? A search by "+" isn't a good idea since there's a lot of math in the code, so this ...

I've gone through and programmed all my domain level logic to interfaces. Now I find that when I want to put data in a bean, the bean doesn't work because the Collection interfaces (Collection, List, Set, etc) do not implement Serializable. Do I need to refactor all my code to use concrete types or is there a better course of action her...
I have been asked to implement a file upload program. The program is a Java Web Start application responsible for uploading the contents of a CD to a web application.

I remember having once seen a list of properties that could be set on Swing components to make them look more native on Mac OS X. This included ways to mark "dirty" documents with the "dot" in the window close button, open dialogs as sheets (not sure about that, but sure would be nice) etc. I know Apple has let Java down as a "primary"...

I read that the date format is ISO 8601 which ...
