Possible to run an EJB3 timer without transaction?

Is there a way to run an EJB3 timer without it being inside a transaction?

Sometimes the methods run by the timer throw exceptions, and I'd like to be able to update a database with a failed flag if that happens. But the EJBTransactionRolledbackException that gets thrown prevents me from doing this.

Thanks.

I hope you can disable the transaction by setting the transaction attribute to Never or Not supported . But I havent tried of this scenario.

I was able to solve the problem by not throwing Timer exceptions up to a common exception handling method. Instead I caught them and dealt with them in the method in which they were caught.

It was turning out that if I threw an exception up the method chain, EJB would automatically embed it in some kind of transaction exception, which meant I couldn't write something to the database notifying people that an exception had occurred. If I didn't throw the exception, then there was no transaction exception involved.
