Hello, i am getting a javax.transaction.TransactionRequiredException: Transaction Required when i try to access (finder method call) my ejb cmp beans from a ejb client. In my client i am using the UserTransction to handle transactions : tx = (UserTransaction) jndiContext.lookup("UserTransaction"); | tx.begin(); | ..... | acces to my cmp bean | .... | tx.commit(); This works fine, when i access my cmp beans on a single jboss. however if my cmp beans are deployed in a jboss cluster im a getting the Exception above, accessing my cmp beans. The transaction type for my cmp beans is "Mandatory", i am using jboss 3.2.7. What can be the cause of my problem ? Is it possible that it has something to do with distributed transactions ? any ideas ? thanks in advance, Andreas View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3959447#...
