i just posted this to the eclipse platform newsgroup and got a response that
answered my question somewhat.
My problem is that i am linking to an external Jar called acmeLib.jar. My
program compiles and can find all the classes i need, but when i go to run,
i get a NoClassDefFoundError.
The answer I got on the platform newsgroup said that i need to link it in
the classpath of my launch configuration, the only place to do that is when
you are running as a Java Application.
So i need to find out how to do one of two things, link the library in the
Run-TimeWorkbench, or launch my plug-in as a java app, but currently im not
sure how to do either.
When i tried to run as a java app, the only feedback i got was in the
console, i got nothing to pop up. All im trying to do right now is use the
hellogef6 example and my acmeLib.jar file together
thank you,
Niall Little

Hi,
Seems like more people are having this problem (including me).
I got the error
Unhandled exception caught in event loop.
when I was trying to use a class from an external jar file.
This error is not completely the same as yours, but i guess our problems are
related.
Finally I got it to work. The solution for my problem was very simple:
- add the .jar file to the Runtime libraries on the run-time tab of the
plugin.xml file.
- copy the .jar file to the root directory of the plug-in.
- run as run-time workbench.
- add jar to the libraries tab on the java build path settings.
hope you can use this info,
Mark
