Chapter 8. Scenario: Aggregation
In the scenario presented in this chapter, we demonstrate the following concepts:
? Protocol transformation
WebSphere Message Broker accepts a SOAP/HTTP request through a
firewall, communicates with MQ clients using the MQ transport behind the
firewall, and responds back to the requester using SOAP/HTTP.
? Data enrichment through aggregation
WebSphere Message Broker aggregates responses from two sources to form
a single message, which is delivered to the requester.
? Request-reply interaction pattern
A request is sent from WebSphere Process Server to WebSphere Message
Broker. A reply is expected.
? Connectivity using a SOAP/HTTP Web service binding WebSphere Process
Server to WebSphere Message Broker using SOAP/HTTP
An HTTPInput node is used in WebSphere Message Broker to receive the
message from WebSphere Process Server. An HTTPReply node is used to
send the response back to WebSphere Process Server.
