So if you are a developer who wants to be productive, and be able to go home on time, and drink beer with your friends, play sports, and generally have fun and be happy ... then read on.
So to understand what FAB is and why it can make your life easier, then I refer you to the following material.
A FAB (Fuse Bundles) is basically a new way of deploying applications into an OSGi container that can make your life a whole lot easier. This technology has been developed by my engineering colleagues at FuseSource and is open sourced at Github, (ASL 2.0 licensed)
Fintan Bolton and his video team have created 2 new excellent introduction videos about FAB.
To go along the videos we have documentation at the Fuse Fabric website. I encourage you to read the material, as its in the minds of James Strachan, who is a driving force behind FAB.
FAB comes out of the box in the new Fuse ESB Enterprise product, however as FAB is open source and freely available, you can use it in general purpose containers such as Apache ServiceMix or Apache Karaf.
