RequiresNew Attribute

If the client is running within a transaction and invokes the enterprise bean’s method, the container takes the following steps:

1. Suspends the client’s transaction

2. Starts a new transaction

3. Delegates the call to the method

4. Resumes the client’s transaction after the method completes

If the client is not associated with a transaction, the container starts a new transaction before running the method.

You should use the RequiresNew attribute when you want to ensure that the method always runs within a new transaction.
