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

See Thread at: http://www.techienuggets.com/Detail?tx=65019 Posted on behalf of a User 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?
