Loading separate JAR files.

Question

Hello.
I have an application that loads functionality from separate jar files so that the application has a "hot deploy" feature. This means that the application reloads a certain functionallity if a new jar is deployed to that folder. This also means that the jars containing this functionality must be in a separate forlder than the jars for the application framework, or the system would try to load this as a functionallity as well.
In my JNLP file, I load the whole application framework at startup, but none of the functionality jars as these are loaded after the application has logged the user in and so on. I use URLClassLoader to load the funtionality classes but in these classes, I import from the allready loaded framework, and the functionalities I try to load throw an excaption that they do not find the classes in the framework.
Any ideas as to how the externally loaded jars can find classes loaded into the framework? This works perfectly well when I don't use web start, so there must be some class loading issues I am not aware of.
Thank you.

Answer 1

OK, I am making some progress, but now I have a different problem: Some of the framework for loading was written by someone else and I would really like access to the debug information it prints without having to rewrite a lot to print it all to files. Is there any way to get access to everything that is being printed on System.out from web start. Been looking around but I can't find anything on the subject.
