Creating a orion-web.xml with the 'search-local-classes-first' attribute in combination with removing the oracle.xml shared libraries has the same effect:
Code:
<?xml version="1.0"?>
<orion-web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-web-10_0.xsd"
development="true"
schema-major-version="10"
schema-minor-version="0">
<!--
dit zorgt ervoor dat classes eerst gezocht worden binnen de jars van de war en dus niet binnen de jar van oc4j http://ralf.schaeftlein.de/2008/11/21/oc4j-and-jaxp-parser-conflict
-->
<web-app-class-loader search-local-classes-first="true" include-war-manifest-class-path="true"/>
<web-app>
</web-app>
</orion-web-app>
