User Transaction Lookup in Unmanaged Threads
Our system is going to migrate from Weblogic 9.1 to Websphere 6.1.19.
The Websphere application server is running under AIX server.
JBPM 3.2.1 is used.
Due to the limitation of the single thread model, I have added multi-threading implementation in each node task action. However, beginTransaction() of Hibernate current session always throws following exception.

I don't have any JNDI transaction lookup problem in Weblogic server but in Websphere. According to the J2EE specification, it states that there is no way to look up user transaction in unmanaged thread. I know Weblogic doesn't strictly follow the specification while Websphere does. Is there any way to solve this problem?
