[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Changing datasource configuration causes Hibernate errors

[treefield]

Hi,

I am using Hibernate in a servlet and I have configured the hibernate.cfg.xml to use a Oracle datasource.  If I change this datasource (up max connections, change the idle timeout), any subsequent calls to the servlet will have the following error...

javax.resource.ResourceException: You are trying to use a connection factory that has been shut down: ManagedConnectionFactory is null.

I believe this has something to do with Hibernate caching the connection and using a connection that has been closed.  I assume that JBoss reallocates the connections and Hibernate has a dead reference to the old pool.  Perhaps this isn't really a JBoss issue but since this is all theory at this point, I thought I would ask...

Thanks!

Theresa
