Proxies are strong features in the Java language package, and similar functionality can be availed from within your JBI ESB using JBI proxies. Interception and re-routing are some of the features we can implement using proxies. You have also seen how an external web service can be bound to the JBI bus and then exposed as proxies within the bus itself so that other components within the bus can route messages through these proxies. The building blocks demonstrated in this chapter can be used to solve your integration problems.

We will look into a more interesting concern in the services network—versioning of services, in the next chapter.
