Hi, I have not tried this looking for timeouts, but try controlling the transactions manually using first @TransactionManagement(TransactionManagementType.BEAN) and | @Resource | UserTransaction utx; | in the following way: | utx.begin(); | ... | utx.commit(); | with exception handling. However it is not clear from your mail if you actually need a transaction that last for 5+ minutes, or if it just is a long-lasting call that happends to be inside a transaction?
