What is the best approach then for a task which might last for 1-6 hours, which is the case with mine. I have increased the transaction timeout already to 2h, but yesterday the task stopped after 2h, without raiging any exceptions. I found the following message in the logs: anonymous wrote : | 2007-06-08 03:59:59,945 WARN [org.jboss.tm.TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=www.timsvenson.de/870, BranchQual=, localId=870] timed out. status=STATUS_AC | I already thought of marking the method with TransactionAttributeType.REQUIRES_NEW, but I'm not sure if this would solve the problem, as there still would be the outer transaction, which probably would time out after 2 h nevertheless. What's the best approach? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4052395#...
