Is there any way to realize a drag & drop function so that the user can move objects (text files, pictures, binaries, ...) from the OS filesystem into a swing application. (eg User drags files into a java swing application)

I think about some kind of Listener/Handler which waits for a binary stream.

The application will be deployed as a Java Webstart Application.

I'm currently moving a webbased application from Tomcat 4 to Tomcat 5.

Tomcat: jakarta-tomcat-5.0.28
Java: j2sdk1.4.2_06
System: Linux 2.6.10 FC3

While migrating I experienced following problem when I start the application:


I start Tomcat from Eclipse with Sysdeo's Tomcat Plugin for Eclipse.

I tried to track down the problem without any result. It seems do be some kind of conflict. The Method org.apache.jasper.runtime.JspRuntimeLibrary.include is located in /tomcat5/common/lib/jasper-runtime.jar so it should be available to Tomcat. This package is also located in j2ee.jar, but I have already tried to exclude this package without any result.

Any ideas???

I have in a program with two JSplitPanes which contain three JLists in it. I use JSplitPanes to put those three JLists under each other in the westPanel.
The problem is that the first JList is reduced to a minimum size and it is so small that you have to make it bigger by hand if you want to read the content.
Does any of you have got an idea how to avoid this "effect"?
//Splitter in WestPanel
JSplitPane westSplitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
JSplitPane westSecondSplitPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT);
westSplitPane.setTopComponent(projectPanel);
westSecondSplitPane.setTopComponent(userPanel);
westSecondSplitPane.setBottomComponent(userinRoomPanel);
westSplitPane.setBottomComponent(westSecondSplitPane);
westPanel.add(westSplitPane);
