EAR classloading error

SourceForge Submitter: misterfrench .
OS: Windows 2000 Professional
JDK: Sun 1.3.1
JBoss version: 3.2.1 with Tomcat 4.1.24

ClassCast exceptions experienced when deploying the
attached testcase EAR.

Investigations have found that if I include xercesImpl.jar,
xml-apis.jar and log4j.jar in the manifest class-path of
the EJB jar in the EAR, I get the exceptions in the
server log attached when JBoss attempts to deploy the
WAR inside the EAR. Removing the entries makes the
exceptions disappear.
