Friends,

I am using WebLogic 8.1 and When I try to run my program, I get the following error. I am using "org.hibernate.transaction.WeblogicTransactionManagerLookup" as my "hibernate.transaction.manager_lookup_class".

Thanks in advance....
Nag.

Hi,
I have the same error. Did you have find any solution?

Hi,
I found the problem solution.

You must configure the hibernate (hibernate.cfg.xml) like this, note the value of "current_session_context_class" parameter to "jta":

<?xml version="1.0" encoding="UTF-8"?>
