[platform-swt-dev] desperate : NoClassDefFoundError on Composite

["Johan Wasserman - BCX - Infrastructure Services" <Johan.Wasserman@xxxxxxxxx>]

Title: Message

I have eventually convinced my bosses that Java is the way to go, got a nice project, wrote it using SWT and everything's fine.... untill now:

 

I need to make the app "stand allone", in other words, not run from the Eclipse IDE.  So my classes are all in the default package (root) except for one or two utillity classes.  All my jars, including swt.jar, is in lib and all the required dll's also lies in the root of the project.

 

So, I jar'd the root of the project and now I'm trying to run the app from it.  So remember all the classes, jar's and dll's are contained whithin the new jar.

 

I get the following error when trying to run the app from the jar...

 

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/swt/widgets/Composite

My main class extends org.eclipse.swt.widgets.Composite and I made the jar runnable (manifest entry).
