Christian, thank you for your explanations. I have some more questions: 1) Can you give me some reference to learn more about transactions that span HTTP requests ? 2) Can @Begin(flushMode=MANUAL) help me ? 3) Why seam has not options that let user manage the transactions as needed ? Am I using seam in the wrong way ? Regards Fab. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043067#...
