too early dispatching of messages
Hi
We have the following problem:
We have a few Session and Entity beans processing incoming JMS messages, which are dispatched by MessageDrivenBeans (MDBs). If JBoss crashes and is restarted, the JMS messages that are still in the JMS Queue, are dispatched. This behavior is correct, BUT the dispatching is done BEFORE the entity beans are ready! The result is a Nullpointer exception (see below), because the store (JDBCStoreManager) is not initialized (yet).
A possible solution might be to start the JBossMQ as the last component. There is this tag in the config files, and we tried different configurations, but we did not succeed.
BTW: With WebLogic the whole thing works "out of the box".
Could someone help us with
- a description, how to start JBosMQ as the last component OR
- a hint on how the dispatching of JMS messages can be delayed until the rest of the app server is up and running
It would be really cool if JBoss could restart without having many ugly exceptions on the console! ;-)
Thanks a million in advance!
Martin
