hi,
is the tag in the deployment descriptor part of the exam ? Also, why methods in session beans can never be re-entrant ?
Quick reminder :


SCJP 1.4, SCWCD 1.4, SCBCD 1.3, SCBCD 5

From my understanding, the reentrant tag is used for multithreading. and in EJB case, the container will handle the threading, so it should be false.

Also, a session bean, stateful or stateless, while serving a client, is dedicated for that specific client only! Other client can't use it. so, the reentrant tag should be false. So is MDB's onMessage() method.


SCBCD 1.3: 94%<br />SCWCD 1.4: 91%<br />SCJP 5: 95%
 
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
