Question

I’ve got a method in a Java EE6 Singleton Session Bean which is called by a @Schedule(…) timer every 30 seconds. This works as expected until an exception is thrown and catched in the method (exception is throw and catched in a try-catch block). After the exception occurs the timer stops calling the method.

How can i force the timer to recall the method again, regardless if an exception has occured or not?

Best regards,

christian

As mentioned in documentation :

• The optional persistent element takes a Boolean value and is used to specify whether the automatic timer should survive a server restart or crash. By default, all automatic timers are persistent.

• An enterprise bean usually creates a timer within a transaction. If this transaction is rolled back, the timer creation also is rolled back. Similarly, if a bean cancels a timer within a transaction that gets rolled back, the timer cancellation is rolled back. In this case, the timer’s duration is reset as if the cancellation had never occurred.

If the timer fails after encountering exception, then the possible approach left will be to create a new timer manually within the catch block.
