Duplicate Entry?

I'm trying to get webapps going as I've been stuck with 977 for some time
now. Sadly I don't seem to be able to get them to work with the latest EAP
either.

I'm getting the following error during compilation:

Error: duplicate entry: WEB-INF/classes/blah blah/AccessRight.class

I've hunted all morning but I can't find out what I'm doing wrong. Anyone
able to help? For the moment I'm switching back to 977.

Regards,

Glen
