ApplicationException, when handled

Imagine that "CreditException" is an @ApplicationException with the rollback=true element.



If the thrown exception is handled, as shown in the above code, do it cause the active transaction to be marked for the rollback?

I feel the guy who started the transaction should receive the exception or else, the rollback will not happen. Ranchers, am I right?

I don't think so. Because first it does not make sense, and second how the container knows that you handle an application exception? The container can know when an application exception is thrown, but it is too much to know detail inside a method that what is going on.

The exception must be thrown by a business / listener method or its interceptor, the container can then intercept it, check its type and rollback attribute, and take proper action. When you catch it inside your method, consume and not rethrow further, is is as if it was never thrown - the container does not now anything about it.
