I need to do a lot of independent updates in one session.(JTA) principaly I need multiple Begin/commit sessions and I use a delegate session to handle the transactions. even though (all/most) transactions are commited successfull i suffer from the main transaction being timed out. This apearently causes all (previously committed ??!?) transactions to be rolled back I understand, seam handles the transactions itself using (8.2Seam manged transactions ) mentions : use an extended persistence context that is scoped to the conversation, instead of to the transaction use two transactions per request; the first spans the beginning of the update model values phase until the end of the invoke application phase; the second spans the render response phase is there some solution to the problem , Whatever happens a long operation gets terminated by a timeout View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4117013#...
