How does UserTransaction propagate?

Question

I have a stateless bean with bean-managed transactions, and a method like this:

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public clas         


        

Answer 1

For EJB3 you normally define transaction propagation with the @TransactionAttribute annotation.

The default transaction attribute for all EJB 3.0 applications is REQUIRED:

If a client invokes the enterprise bean's method while the client is associated with a transaction context, the container invokes the enterprise bean's method in the client's transaction context.

The doc's for transaction type are here: http://download.oracle.com/javaee/6/api/javax/ejb/TransactionAttributeType.html

N.B. Persistence context and transaction propagation typically happen together but not always - beware. For example, stateful session beans may have an extended persistence context.
