JBoss Interview Question:

What if you need to span your transaction across multiple Servlet invocations?

Submitted by: Administrator

You can't with a Servlet. A JTA transaction must start and finish within a single invocation (of the service() method). You should consider using a Stateful SB. In a SFSB with a JTA transaction, the association between the bean instance and the transaction is retained across multiple client calls.
