The simplest way to get started with ServiceMix is to start with the Spring Support. Then you can use ServiceMix inside your application right way, using Spring to wire the components together.

In terms of developing components you might want to check out our Component helper classes to take away some of the plumbing required to write JBI components.
Alternatively you might want to try using our Groovy support to script ServiceMix really easily - or use JSR 223 to use any other scripting engine to script JBI messages and services.
