Resolution: Problem:
When creating the JMS resource and trying to use the auto populated drop-down of ‘com.ibm.websphere.naming.WsnInitialContextFactory’, the user gets a "No class definition" error.
Resolution:
The context factory "com.ibm.websphere.naming.WsnInitialContextFactory", is typically used by WebSphere Application Server applications to perform JNDI operations. The user needs the WAS_ROOT/runtimes/com.ibm.ws.ejb.thinclient_8.0.0.jar in the classpath, where WAS_ROOT is the installation home of the WAS.
