Unfortunately I can't switch to Seam 2 yet (But I'm really looking forward to). The other approach doesn't have any effect. Here is what I do: | @Stateless | @TransactionManagement(TransactionManagementType.BEAN) | @Name("fillDatabase") | public class FillDatabaseAction implements FillDatabase { | | @Resource | private UserTransaction userTransaction; | | ... | | | public void execute() { | | try { | userTransaction.setTransactionTimeout(60*60); | userTransaction.begin(); | doIt(); | userTransaction.commit(); | | ... | Thanks for your quick reply!
