[jboss-user] [EJB 3.0] - references an unknown entity

[Sukar1205]

I am having a problem when I start the JBoss server.
The server keeps failing because of an unknown entity.

this is the code, its a bunch of getters and setters thats all. If you can help why is the server failing that would be great. Please I need to solve this issue fast. I have 2 instance variables projectID and projectID1. Please look at the error below
Many Thanks
