[jboss-user] Re: No transaction is in progress

Hi,
I am facing this same problem. I am having weblogic 9.2 and using JPA over hibernate. For one message at a time it works okay but when I fire good number of events then get into this no transaction in progress issue.

I am using Container managed transaction in MDB. I create entity manager on that thread and save it in threadlocal.. When that message processing is finished finally I close the Entity Manager in onMessage method itself.
throught out the code I use Entity Manager from ThreadLocal which was created at the begning of onMessage method.

It is weird as I am not able to understand why it works sometime and why it doesnt works sometimes.

Did anyone found solution to above problem?
