Resolution

Class com.ca.messagingservice.engine.MessagingServiceApplication is in messaging-engine.jar.

1. Verifying that the file system (your.commonservicesHLQ.CCSZFSB) is mounted to the path specified on the CLASSPATH
   
   
2. Verify that cfgb/messageService/bin/messaging-engine.jar is available.
   
   

   For example:

   JVMJZBL1006I CLASSPATH = /example/cai/CADeploy/CCS/cfgb/messageService/bin/messaging-engine.jar

   The mount point in this example is /example/cai/CADeploy/CCS/cfgb/messageService

3. Next verify that in the ZMSSTART JCL the class name is in lower case as shown below:

ZMSSTART EXEC PGM=JVMLDM86,REGION=0M,
  PARM='+T com.ca.messagingservice.engine.MessagingServiceApplication'
