wsadmin reports NullPointerException on Application Server startup when configuring a listener port
 Technote (troubleshooting)
 
Problem(Abstract)
Using the wsadmin instructions in the WebSphere® Application Server v5.0 Information Center to configure a listener port, an error is reported during start of the application server:

java.lang.NullPointerException at
com.ibm.ejs.jms.listener.MsgListenerPort.<init>(MsgListenerPort.java:132)
 
Cause
One of the Extensible Markup Language (XML) templates that ships with WebSphere Application Server is incorrect.
 
Resolving the problem
Add the following to the generated listener port tags in server.xml:

<stateManagement xmi:id="StateManageable_5" initialState="START"/>

Note: The xmi:id (for example: StateManageable_5) for this object has to be unique in the file.


The debug fix is in the Authorized Program Analysis Report (APAR) PQ74005 for v5.0.1 and APAR PQ79991 for v5.0.2
