Great to hear it's working.

I think there may be a difference in the default artifactId for an  
ejb jar in an ear vs a standalone ejb jar.  I was chatting with David  
J. about this and we determined that the default artifactId for an  
ejb jar is the same regardless if it was in an ear or out... but it  
doesn't seem like this is the case.  It seems you clearly get  
MyEjbs.jar in an ear and MyEjbs (no .jar) out of an ear.

This is likely something we should fix.
