Not able to deploy MDB for JMS-MDB Listener in PRPC V7.1.5

SA-2589

Summary





JMS listener is generating invalid deployment descriptor (ejb-jar.xml) on PRPC 7.1.5 version. 



Error Messages





Below exception is seen in WAS logs:



Parse exception for [ public ID [ null ] and system ID [ null ] ] [ java.lang.IllegalStateException: Parent Translator (EnterpriseBeansTranslator(entity|session|message-driven,1696032023)) did not find a Child Translator for "message-driven-destination".




Steps to Reproduce





1. Create the JMS queue, queue connection factory and activiation spec to be used by the listener on WAS end.

2. Create the JMS-MDB rule instance and generate the XML from Update Deployment Descriptor button on JMS Properties tab.(attachment 1)

3. Add the code snippet generated in step 1 in ebj-jar.xml

4. Update imb-ejb-jar-bnd.xmi file based on details given in the PDN document.

5. Try redepolying the EAR after these changes, we got the execption in attachment 2.




Root Cause





Generated ejb-jar.xml is failing to deploy in application server.

PRPC generated 
ejb-jar.xml  is not compatible with ejb-jar_2_1.xsd. Hence it is not able to parse when application is deployed.





Resolution





Below changes to ejb-jar.xml resolves the issue:



1. Remove below section from generated ejb-jar.xml


<message-driven-destination id="MessageDrivenDestination_CaseMgmtEventListener">

                <destination-type>javax.jms.Topic</destination-type>

                <subscription-durability>NonDurable</subscription-durability>

 </message-driven-destination>



2.Add below tags to generated ejb-jar.xml

 <message-destination-type>javax.jms.Topic</message-destination-type>



3.Remove doctype definition from ejb-jar.xml

 <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd">
