Hi Sankara, That's a clear explanation of what you're trying to do. I believe this is the first time that we've heard someone talk about provisioning OSGi applications from a plain JSE environment. The suggestions above are valid: I would definitely support getting this working on an OSGi runtime first. That will be easier since it's the normal usage of the code in question. Once you've got that working, you can decide whether the cost of porting it to something like PojoSR is worthwhile. Good luck - do let us know how you get on!
