Dead lock when receiving message from a topic

[pierre]

Hi all,
i got a weird problem that looks like this :
http://www.jboss.org/modules/bb/index.html?module=bb&op=viewtopic&t= have two stateful beans that have subscribed to a topic. An other bean posted a message on the topic. And sometimes (about 1 of 100 executions) , one of the two beans doesn't receive the message.

I change the version of jbossmq.jar. (I used jboss3.0.3 and put in lib the jbossmq.jar of the jboss3.0.7 ... )
Then the problem was solved in my development environment.
Following that I put the new version of the jar in exploitation environment. But it didn't solve the problem. I have checked for difference between both environment, and i find that the environment variable JAVA_HOME was not defined and as a consequence tools.jar (provided by the jdk) was not put in the CLASSPATH. Once i have defined JAVA_HOME, the problem was solved. (definitely i hope)

Does someone see a link between the non use of tools.jar and the dead lock ?

Thanks,

Pierre.

PS : I use jdk1.3.1-5 on HP Tru64 Unix

Are you sure this was the problem at all? A session bean must not attempt to receive messages from a queue or topic at all. This is why message driven beans exist. How are you handling passivation and/or destruction of your session bean?

Yes, sorry, you're right.
I'm using 2 mdb to receive messages.
