Hi,
I'm using JBoss 3.2.7 with jdk1.4.2_06 on windows 2000 server and I get the following error with my program:

17:09:41 ERROR [org.jboss.ejb.plugins.jms.JMSContainerInvoker] (JMS SessionPool Worker-0:) Exception in JMSCI message listener

I don't know where it comes from considering that I have many EJB (MDBs and session beans) and services.
I've thought it could come from the sleep method that I call in one service but I don't know why that could do that.
any light would be helpfull
Thanks
