What exactly are you trying to do, can you give some more details ? I am not able to understand what exactly are you doing with Ecllipse RCP .
I'm trying to run an embedded ejb3 server as an eclipse plugin for a seperate UI plugin to talk to. Having challenges trying to get the embedded ejb3 server to pickup the EJB3 beans from the classpath.
A detail is posted here under the EJB3 forum (and you'll note that I'm still not sure which forum this should be posted to): http://www.jboss.org/index.html?module=bb&op=viewtopic&t=91457
