Web Service Versioning Sample using
ESB
We discussed the theory of web service versioning, now it is time to put that in code.
Let us do that with the help of a sample use case. One thing to be noted here is that
to implement the sample we make use of EIPs building blocks which are described in
detail in a chapter of their own.
Sample Use Case
The sample use case is about setting up the JBI components to effectively enable the
versioning mechanism in the services. All these components are configured in the
ESB. An external client interacts with the ESB thus testing the versioning mechanism.
The ESB is bound to the different versions of services, which are defined external and
remote to the ESB. The ESB will apply the versioning rules and route the requests
to the respective version of the service. The sample use case is illustrated here in the
following figure:

In fact this sample is not as complicated as the figure make it look.
