Subject Re: Problem in extending class

Nah. commandline will never get me the hierarchy that I want. java.exe
only accepts a flat set of urls.

What I'm doing is to have a proxy class: MainProxy.

1. A system property will be set (say, set it to "lib") to call MainProxy
2. Another system property is set to the actually class name.
3. when MainProxy takes controll from within the new vm, it reads the
class path tree property (which is "lib" in this case).
4. MainProxy creates a tree class loader that looks recursively into
all jars under lib.
5. MainProxy loads the target class using the tree class loader.
6. MainProxy also needs to set the thread context class loader.

And there it goes.

It's just the commons-logging thing always giving me problem. Had to
do ugly work-around for it.
