We are using WAS 6.0.2 and MQ v 6.0 installed on AIX box.

When we try to run any code that accesses MQ using base java we get the following error

Caused by: java.lang.NoSuchFieldError: msgToken

I understand that this is a problem with WAS 6.0 because of older set of MQ jars and the solution is to change the MQ_INSTALL_ROOT to point to the MQ Installation dir.

However, there is a particular problem which we are not able to resolve. When we refresh the page, the error we get is different than what comes in the first time

Is this error also related to the same problem.

We have kept the new com.ibm.mq.jar in the WEB-INF/lib folder of the application and also added the /usr/mqm/java/lib and all the jar to the classpath.
