cocoon classloader problem

[Thomas Haditsch <th...@thomminator.de>]

while trying to get the cocoon command line interface to work, i stumbled
across this odd problem:

Object o = 
Class.forName("org.apache.avalon.excalibur.xml.JaxpParser").newInstance();
org.apache.cocoon.util.ClassUtils.loadClass("org.apache.avalon.excalibur.xml.JaxpParser").newInstance();

the JaxpParser class obviously is in the class path, since the first line 
gets executed without
problems... but when trying to use the cocoon class loader, i get this:

java.lang.ClassNotFoundException: org.apache.avalon.excalibur.xml.JaxpParser

anybody got a clue why it can't find a class that's available in the 
classpath? i'm wondering
because the build script for the docs seems to manage this, while this code 
doesn't.

thanks in advance.
