Thanx. Are you doing this for a school project? IIRC, I think you mentioned > something like that on the list... I'm doing it in my free time.

It implements the OSGi url handler and when requested it will take the wrapped jar, use bnd to actually do the wrapping and give back an input stream to the resulted OSGi bundle. What the "user" of the wrap: url does with the input stream is not in the scope of wrap handler. In runner, the input stream is saved to the cache folder as a file (jar) and is passed to the target platform.

I saw this white box model referenced as the name for how extenders work on some mail lists and I also recall something from Knopflerfish docs bu I can not trace back those references. We can call it also extender model/pattern if you consider is more clear. What is a use case for the classpath handler? I thought that the whole > purpose of grouping in bundles was to control how resources are > accessed... aren't you making a mess of this? If someone needs access to a resource from classpath as for example a configuration file it needs to access it via BundleContext. If this is done via programming then is easy because is just a call you have to write. But when you have to express it in a configuraion file this is not so easy anymore. Using classpath: urls is a conscious action so it's up to the user if he uses or not. I'll probably have more questions later, but thanks for now! > > Dave > > > > > _______________________________________________ > general mailing list > general@lists.ops4j.org > http://lists.ops4j.org/mailman/listinfo/general >
