isolate war deployment
I would like to isolate my war deployment respecting to the classic servlet 2.3 class loading model (load the classes from the child scope first: WEB-INF/class + WEB-INF/lib first, then load the classes from the parent scope).
Here is my jboss-web.xml:
<jboss-web>
<!-- Isolate the application classes from other deployments
-->
<class-loading>
<loader-repository java2ClassLoadingCompliance="false">
app.TracerTrac:loader=TracerTrac.war
<loader-repository-config>java2ParentDelegaton=true</loader-repository-config>
</loader-repository>
</class-loading>
</jboss-web>
Nevertheless, somhow the war classloader is loading the classes from the parent scope first.
Here is the error:
10:10:42,829 ERROR [ActionServlet] Parsing error processing resource path /WEB-INF/struts-config.xml

The conflict is about the jar: commons-digester.jar located under: MyWebApp/WEB-INF/lib and jbossweb-tomcat50.sar
Here are the JMX console traces:
