Hi All,

We have upgraded JMS listeners and JMS-Connectors from Pega 7.2 to Pega 8.6.1 platform with smart investigate frameworks. After that, we are facing the below exception in the JMS connection, please suggest a solution if you'd have faced the same.

Exception : Couldn't resolve JMS connection factory object 'java:comp/env/jms/PEGAQueueConFactory' from JNDI server at , javax.naming.NamingException: Unexpected exception resolving reference [Root exception is java.lang.NullPointerException]

We have migrated from WAS-based setup to Openshift Container-based platform where Pega is running on Tomcat App server. The following configurations are defined in the context.xml file and web.xml file. 

web.xml file : 

<resource-ref id="PEGAQueueConFactory">

<description>PEGAQueueConFactory</description>

<res-ref-name>jms/PEGAQueueConFactory</res-ref-name>

<res-type>javax.jms.QueueConnectionFactory</res-type>

<res-auth>Container</res-auth>

<res-sharing-scope>Shareable</res-sharing-scope>

</resource-ref>

context.xml file :

  <Resource name="jms/PEGAQueueConFactory"     auth="Container"    type="com.ibm.mq.jms.MQQueueConnectionFactory"    factory="com.ibm.mq.jms.MQQueueConnectionFactoryFactory"    description="PEGAQueueConFactory"    CCDTURL="file:///usr/local/tomcat/conf/CHL-PEGAQueueConFactory.TAB"    CNLIST="******.APPS.***(1111)"    CROPT="77777"    CRT="888888"    EXP="99999"    QMGR="Server.MQ"   />
