Thank you for all your help. I got everything running by importing the jars you listed from my server into my Jboss server lib into my maven repository. I also fixed my client connectivity issue by upgrading to Spring 2.5.3, and using the org.springframework.jms.connection.CachingConnectionFactory to create and pool the same number of JMS connections as partition readers. Doing this greatly increases my performance. Running my client and JBoss on my dual processor machine, I can now queue around 1000 messages a minute, give or take a few depending on the size. I deployed this to our blade clusters and I had nearly an exponential increase in processing speed as I add new Messaging nodes. With the POJO read process on its own blade, and 2 JBoss nodes on a blade each, I can queue almost 3000 messages per minute! In our previous implementation with MQ, we could only get 500 a minute!
