--------------------------------------------------------------
After some research I'm not certain I can get the behavior I need.
I was able to isolate transactions for a specific use case where I know the 
invoking client does not have a transaction:

  invoke Task [SSB with @TransactionAttribute(NOT_SUPPORTED)]
          invoke Search [SSB with @TransactionAttribute(REQUIRED)], look up 
entities to operate on
          for each entity
            invoke Operation [SSB with @TransactionAttribute(REQUIRED)], 
perform operation

This does execute the Search and Operation methods in separate transactions and 
allow run times greater than the default timeout for the Task method.
However, if the client invoking Task is not an MBean, but rather another 
business component, it's transaction will be suspended while the Task runs and 
will timeout after 5 minutes.

So am I understanding this correctly?
You can gain some control over transaction timeouts, but only if you know your 
clients are not using a transaction.
