Hibernate unable to startNewTransaction

[tvaishnav]

I am using JBoss 4.0.3, hibernate3 and Oracle 10gi. The scenario is:
I have a EJB method that starts a transaction. This method after starting transaction calls another method say A() in some class (which is not an EJB). This method A() starts a new transaction using hibernate and then calls another method say B() which also tries to start a new transaction but fails and throws the following exception:

[JTATransaction] [ERROR] JTA transaction begin failed
java.lang.IllegalStateException: Trying to change transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=magnolia.storeperform.com/18, Branc
hQual=, localId=18] in enlist!

Does anyone has an idea as to what's wrong with this?

Thanks

In your specific case i guess you are starting different transaction with in a single threaded call. Lets say you have to start a new transaction from an EJB you have to look up again another component to do it. In shor you can have nested transactions withh in a single thread.

Hope this helps,

Ignore the earlier post. In your specific case i guess you are starting different transaction with in a single threaded call which i guess is not possible. Lets say you have to start a new transaction from an EJB you have to look up again another component to do it. In shor you cannot have nested transactions withh in a single thread.
