My system currently is Jboss 2.4.0.23 running on Linux and client running in VAJ 3.5.3 in Win2000. And I am still trying to get JBossMQ to work at least little bit. Does anyone have better luck and have it actually working? What protocol you use RMI, OIL or UIL?
Our system desing is so that clients call methods in stateful session bean that can cause JMS messages to sent out to all clients (ObjectMessage into Topic), message are beeing sent from this stateful bean or from stateless bean it calls.
When testing with 2 clients and with RMI get 100% times following message
into server console and other client stops receiving messages. For three
it so far has been so that one client stops receiving messages and 2 continue
receiving them, but haven't done so much testing with 3 and at least once
not single one of my clients received any messages..

Default OIL is worse.. it receives messages quite happily for while, until it throws 3 times same exception (all clients get same 3 and it is always same 3 no matter how many messages have been delivered). And after this all clients stop receiving messages.

And when close clients (and release resources) get following output to console window.
