NoClassDefFoundError: javax/resource/ResourceExceptioin

I have compiled successfully a small java program on a Solaris 10 box. When run I get the exception in thread main stuff and the NoClassDefFound in the title. What am I missing in my java environment?

The javax.resource.ResourceException is from J2EE 5 are you using J2EE APIs also?

I am using a set of IBM MQ Series jar files:

com.ibm.mq.jar
com.ibm.mq.jmqi.jar
com.ibm.mqjms.jar

There is a class named com.ibm.mq.MQEnvironment that is throwing the error (MQEnvironment.java:570) when I set some variables in it with code like:

MQEnvironment.channel = "whatever";

the error occurs.

I think the MQ series API uses the J2EE framework, so you need to have the j2ee api jar files also in you class path for execution
