Solving IBM MQ Java code version mismatches using the mqjavalist.sh script

Troubleshooting


Problem

When Java™ SE applications and Java EE application servers such as WebSphere Application Server do not use a consistent set of MQ Java archives, applications can fail in unpredictable ways. If WebSphere Application Server notices a mismatch, it issues this message: "MQJCA1008 The WebSphere MQ classes for JMS were found in the class path but were not the correct version. This error can occur if the application server finds an earlier version of the WebSphere MQ classes for JMS in the class path. The error can also occur if you do not configure WebSphere Application Server to use the correct version of the WebSphere MQ classes for JMS."
