WebLogic: The Definitive Guide Review by H. K Sujathan

Regarding JMS redelivery

In chapter 8 author wrote a note: Even with container managed transaction in MDBs there may be message redelivery .The Cause - was pointed out as possible server crash. But why was important point that onMessage exceeding transaction-timeout also causes message redelivery left out?? Topics lack depth.. Things like what happens when is exceeded in MDB, stateless EJB etc is not written crisp and straight.. Didn't like anything much including clustering, JVM tuning etc.. What I expect is - that which is not there in weblogic documentations.. Something extra is needed based on extensive author experience.
Go for book like "BEA Weblogic Server 7.0 deployment and Administration"- Aaron Mulder- Wrox.
