create JAR-file: works in Eclipse, not in NetBeans
I am running Eclipse 3.2 and NetBeans 5.5.1 and tried to create a JAR file of my project. This works fine in Eclipse - but not in Netbeans; when creating a JAR file in Netbeans I can start my application but the whole GUI isn't being displayed. I don't get an error message or another feedback.
I am working with the JDK 6 Update 1.
Where can I start troubleshooting?
