Hello all, I am Bharath kumar and this is my first mail to this group. I am following River framework for the last 8 years. I have been using OSGi framework for the past 7 years in various projects.
I made lot of attempts to use jini with OSGi framework. Recently I got some success using River 3.0.0 version. I created 3 OSGi bundles based on River code. 1. River core classes as system fragment bundle. 2. Bootstrap bundle to start code server, Lookup discovery manager, export remote services. 3. Lookup service. I made some minor changes to River classes (10 Classes) to resolve class loading issues. I have excluded other services like transaction services, Java space services. I am using eclipse and bndtools for the development. I am ready to share these 3 bundles to this great community.

The maven-bnd-plugin does most things right, but there is always a question of hiding internal packages/classes. Instead of aiming for running 'naked' on a blank OSGi container, I think it is generally better to start out with something like Apache Karaf. It will provide a lot for relatively little, incl so called wrapping of JARs into Bundles, provided by Pax URL[1] project, which also provides URL references of various kinds for many things. So, even if not going with Karaf, take a look at Pax URL. And in River, there is likely to be classloading issues, and although "Dynamic-ImportPackage" is available as a last resort, it should be avoided. Almost always the context classloader is a "mess", and there is a tendency of memory leaks when it is involved.
