    https://pdn.pega.com/deploying-jms-message-driven-bean-mdb-represents-jms-mdb-listener-pega-7
  2. Post a JMS message into the destination


Root Cause



A software use or operation error. Pega evaluated the posted Text Message as a Map Message. The Requested Type is set as Map Message in the Service JMS rule, by default.


Resolution

Perform the following local-change:
  1. Reconfigure the JMS Service Request rule by changing the Request Type in the Request tab
  2. Restart the server
