JMS synchronous invocations are further explained in the following use case.
Use case
When the proxy service named SMSSenderProxy receives an HTTP request, it publishes that request in a JMS queue named SMSStore. Another proxy service named SMSForwardProxy subscribes to messages published in this queue and forwards them to a back-end service named SimpleStockQuoteService. When this back-end service returns an HTTP response, internal ESB logic is used to save that message as a JMS message in a JMS queue named SMSReceiveNotification. Then this response is taken from the SMSReceiveNotification queue and delivered to the client as an HTTP message using internal ESB logic.
The following sub sections explain how to execute this use case. Here, the Message Broker Profile of WSO2 EI is used as the JMS broker.
