Re: Classloading Problem

I would try to recreate this in a debugging environment, preferrably 
with a breakpoint when java.util.zip.ZipException is thrown.
Also make sure there are only .jar files and directories in your 
classpath (application.getAttribute("caucho.class.path"))

You probably won't get much help with a version of Resin as old as 
2.1.6. Have you tried with 2.1.17?
