Mysterious javax.ejb.CreateException
I've written a client app that accesses a CMP entity bean that I've written. The bean deploys successfully and I can call finder methods on it. However, when I call a create method on the bean, like this:
Concept con2 = (Concept) home.create();
I get this stack trace in the client:
javax.ejb.CreateException: Cound not determine existence:javax.ejb.FinderException: This statement is closed.

Can anyone tell me what's going wrong? BTW, I'm running Jboss 2.4.5.
Thanks in advance,
