I tried to deploy an auto generated deployment descriptor (ejb-jar.xml). Due to autogenerating with xmlbeans all elements were prefixed with "j2ee:". I attach the file in this message. When removing all prefixes, the deploy works fine.

<?xml version="1.0" encoding="UTF-8"?>
<j2ee:ejb-jar version="2.1" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee">

Deploying this file will case the deployer to throw an exception.
