[jboss-user] [EJB 3.0] - Re: Stateful bean keep-alive

Hello Peter,

thanks for your reply.

unfortunately, our session bean cannot be serialized from various reasons. I am moving an existing, a little bit larger, application into JBoss. It would be not easy to make it serializable. (Maybe in the future I will have to do it anyway.)

First, the thread must not lookup the EJB itself - you will end up with a new EJB, not with the one that you want to keep alive. Therefore, you must pass the bean's proxy to the thread. Second, I recommend creating a separate method on the EJB that does nothing - the primary purpose of this method is for the extra thread to occasionally call it. This should guarantee that the state of the bean does not change inadvertently.

Yes, that what I have already done :-)
