This will help you to integrate
in a loosely-coupled manner which will facilitate easy service collaboration and
orchestration. The next chapter will show you a sample of aggregating multiple
services on the ESB using the EAI patterns and guidelines which we learned in
this chapter.
Sample Service Aggregation
In the previous chapters we covered many JBI components in ServiceMix and also
saw a few useful use cases to help solve real life problems using the ESB patterns.
Another useful application of ESB is to provide a "Services Workbench" wherein
we can use various integration patterns available to aggregate services to carry out
business processes. We will look into such a sample use case in this chapter.
We will look at the following topics in the business integration sample:
Solution architecture
JBI-based ESB component architecture
Understanding the message exchange
Deploy and run the sample
Provision Service Order??”Business
Integration Sample
To demonstrate the service aggregation, we will choose a typical business integration
scenario happening as an outcome of a customer attempting to make a web order
entry.
