Hey @akg17,
I’m not sure I 100% follow. Are you just using Spring Cloud Stream or are you trying to send/receive messages between some apps using Spring Cloud Stream and others using JMS?
Note that the Solace Spring Cloud Stream binder does not use our JMS API so you wouldn’t use JMS concepts when using it. If you want to consume a message to access the headers, etc. in Spring Cloud Stream use the Spring Message: org.springframework.messaging.Message.
