Message Interaction Patterns
November 24, 2009[From Builder AU]
In every business process, messages are exchanged between participants. So far we have only looked at simple interactions, that is a single request followed by a reply, whether synchronous or asynchronous.
Asynchronous messaging adds additional complexities around the routing and correlation of replies. In this chapter, we will look at how BPEL PM uses WS-Addressing to manage this and in situations where this can't be used, examine how we can use correlation sets in BPEL to achieve the same result.
