I have a JAX-WS 2.0 RI based project deployed on JBoss 4.0.4.GA that I am upgrading to JBoss 4.2.1.GA with JBossWS 2.0.1.GA.

Deployment of the .war fails with the following stacktrace:

The war file contains the following jboss-web.xml:


  | <?xml version="1.0" encoding="iso-8859-1"?>
  | <!DOCTYPE jboss-web
  |   PUBLIC "-//JBoss//DTD Web Application 2.4//EN"
  |          "http://www.jboss.org/j2ee/dtd/jboss-web_4_0.dtd">

  | <jboss-web>
  |   <class-loading>
  |     <loader-repository>
  |       xo.loaders:loader=HVODImportWebService.war

  | 
  |   <use-session-cookies>false</use-session-cookies>
  | 
  |   <depends>xo.services:service=ConfigurationManager</depends>
  | </jboss-web>
  | 

When I remove the loader-repository configuration, deployment is successful.  I'm not entirely sure why I have a habit of declaring loader-repository for all my deployments, it definitely began with my quest for isolated-classloaders, but is probably superfluous now that I have isolated classloaders properly configured in conf/jboss-service.xml, deploy/ear-deployer.xml, and deploy/jboss-web.deployer/META-INF/jboss-service.xml server configuration files.
