Problems with cocoon

[raul tebar]

Hello, I need some help,
After installing cocoon I've tried to run the Cocoon.xml example, but
it reports me this error (see error.txt at end).
Can anybody help me out with this so I can progress with the installation,
many thanks in advance.

You have to play hard with the classpath. Make sure xerces/xalan that came with Cocoon are before any other xml parsers. You can rename jar files etc.
