reentrant tag

[Celinio Fernandes]

hi,
is the tag

 <reentrant> 

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

 <reentrant> true </reentrant>
<reentrant> false </reentrant>

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.
