Hi Rafa, How much of the OSG is exposed through osgvp? Is it possible to extract out the wrapping into a separate project? I've been looking into how I can use maven and jna to possibly get access to OSG from java but I'm just beginning. If the work is already done or you have some tips/pointers on how to get going that would be great. Gerrick
