I'm running JBoss3.0.4 and tomcat4.1.12 on Win2000.
And I'm using Java1.4.0.

I have two applications, which send and receive JMS message each other. When I execute these applications on Win2000, it works very well. No problems.
But when I execute my applications on WinXP, they cannot receive any JMS messages. No errors when connecting to JBossMQ.
I tried on Java1.4.1. But it doesn't work, too.
