Hi, i just had a sample test for wl 6.0 test from bea. i couldn't understand why the answer to the following question is D. Which of the following JMS message acknowledgment options minimizes session overhead? A. NO_ACKNOWLEDGE B. AUTO_ACKNOWLEDGE C. CLIENT_ACKNOWLEDGE D. DUPS_OK_ACKNOWLEDGE I thought WL has a proprietory acknowledge mode - NO_ACKNOWLEDGE, which doesn't require any acknowledgment after message delivery to client. so, i thought this should have less overhead than DUPS_OK_ACKNOWLEDGE. thank you, -andrew
