    text
    copied!<p><strong>Issue:</strong> Having multiple consumer applications active specification attached to a single MQ on distributed VM servers is causing a null payload in a MQ Message. Note: See notes at the bottom. No issue with mq.</p> <p><strong>Details:</strong> I have 3 Websphere applications deployed across 2 VM servers. 1 application is a publisher and the other 2 applications are consumers attached to a single MQ Manager, and MQ. 2 consumer applications are pulling off the messages and processing them. The consumer application on the separate server receives a null payload. I have confirmed that its seems to be an issue having multiple application server instances attached to MQ. Confirmed by deploying the publisher on server 2 with consumer 2, then consumer 1 fails.</p> <p><strong>Question:</strong> Has anyone tried attaching multiple MDB applications deployed on separate server instances bind to one Queue Manager and one MQ?</p> <p><strong>Specifications:</strong></p> <p>Websphere 7, EJB 3.0 MDB's,Transactions turned off,Queue in a queue installed on another machine.</p> <p><strong>Goal:</strong></p> <p>Distributed computing, scaling up against large number of messages.</p> <p>I'm thinking this is a configuration issue but not 100% sure where to look. I had read that you could use MQLink, but I don't see why I would need to use service bus integration.</p> <p><strong>Supporting Doucmentation:</strong> [MQ Link][1</p> <p>UPDATE: I fixed the problem and it was a related to a combination of class loader issue with a duplicate classes. See Solution Notes below I added.</p> <p>EDIT HISTORY: - Clarified specifications, clarified question and added overall goal. - reference notes to solution.</p>
