Subject: Re: classloading within an EAR file problem

Despite Tomasz's optimism I don't think you can do this.  In geronimo  
the rars and ejb jars in an ear get put in one classloader and each  
web-app gets put in another classloader.  The ear classloader is a  
parent of every war classloader.  The problem is that the war  
classloaders don't get publically accessible names that you could use  
in the dependencies section to make one a parent of another.

I'm afraid your best bet in geronimo is to put the shared classes  
into a jar in the ear's lib directory.  I would not object in the  
least if you raised a jira for this issue but I doubt I personally  
will be able to work on it very soon.

thanks
