What is the return type of the create method in your home interface?
Is it the bean class or the remote / local interface?
If it is the remote / local interface is it the correct one for the home interface type?
I have found the mistake. I miss some java.rmi.RemoteException throws at the end of some Entity-Homes :(. Now I've new errors ;-).
But thanks for your support.
