Message exchange takes place through
different MEPs, each providing different levels of reliability.
The next chapter will introduce a JBI container. Be ready to wet your hands with
some code too??”to build and deploy your first JBI sample.
JBI Container??”ServiceMix
The first two chapters introduced ESB and JBI respectively, with much theory and
less of code. Just like me, you too might have come across a lot of white papers
and point of views on the above two technologies. However, when we want to
actually implement them into our technical architectures, we need working code
demonstrating both.
Just like any other Java APIs, servlet or EJB, for a JBI API too, we need concrete
implementation. There are many implementations supporting ESB architectures
available in the market today. A couple of them can interoperate with the JBI API
whereas a few others tackle JBI on the side of quite a different programming model.
ServiceMix is an open-source ESB platform in Java programming language, built
from the ground up with JBI APIs and principles.
Due to the reason quoted in the first paragraph, we will use ServiceMix to better
understand JBI and ESB.
