Hi,

This is a question from a mock exam.

Which three are true about JAX-RPC Web services? (Choose three.)
A. EJB based endpoints can use container-managed transactions.
B. Servlet-based endpoints can use container-managed transactions.
C. Client-initiated transactions are propagated to EJB based endpoints.
D. EJB based endpoints can programmatically demarcate transactions.
E. Client-initiated transactions are propagated to Servlet-based endpoints.
F. Servlet-based endpoints can programmatically demarcate transactions.
Answer: ADF

Why is C not correct - Client transactions can be propagated using Required and Supported trans attributes , right?

Also,

Why is F correct - A JSE would need something like JTA for transaction separation , right?

So is ACD the correct answer? Do let me know what you think.

It would be helpful for other people if you could mention the name of mock i.e source exam from where you have picked
up the question.

Best Regards

Any clue to the answer? Is my reasoning sound or is it outright wrong?
