This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
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.
Why is C not correct - Client transactions can be propagated using Required and Supported trans attributes , right?
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.
