Custom Content handler

I get the following error:
java.lang.NoClassDefFoundError: com/wm/app/b2b/server/ContentHandlerFactory

when I try to register a custom content handler using the ServerAPI.registerContentHanlder().

This class seem to be in the class path my content handler is also in the path. Can someone please point what am I missing.

Thanx
