How do I find a class if I don't want to use a jar in osgi?

There might be non-standard ways to load classes, but there is no ways to do that with pure OSGi. In OSGi the bundle (the jar file) is the delivery package that can be loaded and managed by an OSGi framework. Usually, each bundle is loaded by an separate classloader.

You gain a lot with that: you specify which packages with which version a bundle exports or imports. In the Manifest you indicate these relationships in an orderly manner. This ways the OSGi framework is able to manage the dependencies without interrupting other bundles.

If you are trying to replace the class for debugging purposes, you could try a remote debug on a VM that supports hot code replace. This will allow you to step through, find a problem, and fix it without restarting OSGi.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
