> Project: Geronimo
> Issue Type: Improvement
> Security Level: public(Regular issues)
> Components: console
> Affects Versions: 2.0
> Environment: Any
> Reporter: Rakesh Midha
> Assigned To: Kevan Miller
> Fix For: 2.0

> Attachments: classloader.gif, classloaderView2690.patch,
> classloaderViewLinks.patch, common.patch
>
>
> Looking into the classloader problems and knowing which classsloader loaded
> which class has always been a big problem in app servers.
> So many times we hit ClassNotFoundException and wonder why is it happening
> when the classes are available in my module. It may be because those classes
> are loaded by some other classloader.
> I think it would be nice if we can add a view in console which shows are the
> classloaders and the classes they loaded.
