Hi,
I'm trying to create a one to many bidirectional relationship but am having
some problems. Whenever I deploy the application in JBoss I get an error.
I've searched online, and in an EJB 3.0 book and as far as I know I am doing
things correctly. Below are my 2 classes, the tables and the error from JBoss.
If anyone can point me in the right direction it would be helpful. I am using
JBoss version 4.0.4.GA. This is my first EJB application, so I appoligize if
this is a simple error. Thanks!
