Jdeveloper + OC4J Problem

Question

Hi all,
I have an application that runs fine on tomcat and any other app server. When I try to run it from within Jdeveloper, for some reason I get all sort of class-loader or xml parsing problems.
So it turns out that embedded oc4j tries to use its own xml parser, its own struts jar and this causes a lot of problems and it throws errors and I can't run this app.
Please how do I turn off jdeveloper/embedded OC4J from using its own jars and rather just run the app, since the app has all needed libraries ?
Here's a sample error -
SEVERE: MessageResourcesFactory.createFactory
oracle.classloader.util.AnnotatedClassNotFoundException:
     Missing class: org.apache.struts.util.PropertyMessageResourcesFactory
     Dependent class: org.apache.struts.util.RequestUtils
     Loader: current-workspace-app.web.zeims-c:0.0.0
     Code-Source: /C:/devtools/java/jdeveloper/jdev/mywork/zeims/customer/lib/struts.jar
     Configuration: <classpath> in C:\devtools\java\jdeveloper\jdev\mywork\zeims\customer\public_html
This load was initiated at current-workspace-app.root:0.0.0 using the loadClass() method.
Pls help !!!

I think that i they works is lucky, because your two modules get managed through the same class loader in your standalone oc4j
Correct if I'm wrong, but you should not trust using local references if they aren't implemented in the same instance of the classloader, which you can control
