JBoss 2.4 + Tomcat 3.2.2 + Cocoon 2.0b1; SAXParser problem

Sun, 15 Jul 2001 02:05:37 -0700 

Hello,

I've tried to run Cocoon 2.0b1 (and also the latest CVS version) inside JBoos 
2.4 (which is running combined with Tomcat 3.2.2).

I get the following error when I go to http://localost:8080/cocoon/

--------------
type internal-server-error

message Exception in Handler

description org.apache.cocoon.ProcessingException: Exception in 
Handler:org.apache.avalon.framework.component.ComponentException: 
markup-languages: ComponentSelector could not access the Component for hint: 
sitemap
--------------- (see attachment for complete error)

It boils down to a cannot find SAXParser (from Xerces). I've already changed 
the jboss and tomcat XML parsers to Xerces 1.4.

Any suggestions?

Thanks
Ewout
