Thanks for your answer. The method call to - > processA , which call to xxx() wich call to yyy()... somewhere in the middle for example in yyy() an exception (rollbak exception) is thronw and catched , so the code is not usefull. i need to know where in my code (if there is) exception is thrown and catched without throw it to the caller level.
