I am not sure I can help you without more information. All I can do is ask questions.
What are you trying to deploy? A Single CMP? Multiple CMPs? An EAR?
Do all of your ejbs compile under ejbc without errors? Have you ever been able to deploy the application or has this error always happened?
Are you deploying to a single server instance or a clustered environment?
