TRANSACTION ROLLBACK EXCEPTION - [b]NullPointerException[/b]
Hi, there.
I am developing CMP Beans under JBoss 2.4.4 and am experiencing the following error.
I was trying to use findAll() method from home interface.
It returns all the key classes as normal, but I can not use remote interface methods at all. And the system displays the following error.
Can anybody help me?
