java - Ejb, Error in second method rolls back first method -

i have poller scheduled this

@schedule(minute = "*/5", hour = "*", persistent = false) public void polltimer() {      startfirstpoller();      startsecondpoller();  } @transactionattribute(transactionattributetype.requires_new) private void startfirstpoller() { // find booking database , update bokingfacade.findall();     bokingfacade.update(booking); } @transactionattribute(transactionattributetype.requires_new) private void startsecondpoller() { // find booking updated database , update bokingfacade.findall();     bokingfacade.update(booking); } 

the first method update bookings, save them database , second method use updated information process further , again update database. problem changes doesn't reflect in database until , unless second executes successfully. moreover, exception in second method rollback successful changes made first method. please let me know happening , how make 2 method independent of each other.

i assume because don't define start , end of transaction managed container , spans entire execution.

you can manage transactions using annotations in java ee. jta api transactions.
