I have a top level war file running properly in Tomcat, now I am trying to move it to Jboss AS 6 Final.

Because of conflicts in XML parser/transformers,  I had to insulate this war file from everything else.  This is my jboss-classloading.xml under WEB-INF:

<classloading xmlns="urn:jboss:classloading:1.0"

name ="generator.war"

top-level-classloader ="true"

export-all="NON_EMPTY"

import-all="true">

</classloading>

All of the libraries are put in WEB-INF/lib

But then some class-loading issue start to show up, 

class-nof-found problem: commons-configuration class can not find class in commons-lang.  But both jars are found in WEB-INF/lib,  then I extract classes from the jars and  jar them together in one single jar file,  still the same problem.

: org.apache.commons.lang.text.StrLookup from BaseClassLoader@5fadce{vfs:///C:/jboss6/jboss-6.0.0.Final/server/default/conf/jboss-service.xml}

Another problem was illegal access error,  looks to be related to parent and child classes loaded from two different class-loaders.
