[C2] Classloader not working with multiple Cocoon versions

[Stuart Roebuck <st...@adolos.co.uk>]

Trying to get the latest version of Cocoon running I've come across a problem which may or may not be new news to folk, but was certainly causing me problems getting things running.

I was installing the new version of the cocoon webapp into an Tomcat setup which included two other contexts with older versions of Cocoon 2 in them.

When I tried to access http://localhost:8080/cocoon/ I was getting an error, and looking at the cocoon.log I was finding that the Classpath output by cocoon did not contain any of the library entries in webapp/cocoon/WEB-INF/lib/ - this sent me on a long wild goose chase.

I put in some additional debug traces and discovered that they weren't showing.

Then I tried removing all references in server.xml to my other two cocoon contexts and ran again.

It worked!

So, it appears that the classloader is using the cocoon classes from one of my older external webapps defined in server.xml rather than from the cocoon webapp in tomcat/webapp.

Any thoughts?

Stuart.

Maybe. I'm still not entirely awake this morning (bad night), but try
using the new ParanoidCocoonServlet instead of CocoonServlet? I believe
this uses the new cunning classloader etc.
