I have a fairly basic EAR structure, containing one EJB project and one WAR project, that I am attempting to deploy in a JBoss 6.3 EAP environment. I have already successfully deployed it in a 5.1.0 Community and 5.2 EAP environment, however while migrating to 6.3 EAP I am running into a pretty major and undescriptive issue. Upon attempted deployment of the EAR, I get a NullPointerException that is thrown on the WAR. In an attempt to determine exactly what was going on I extracted the WAR by itself and tried deploying it with just the EJB module along side it (for dependencies). The following is the exception that is thrown:

I have gone through the pain stacking process of adding things in one at a time until I get this exception thrown and I have narrowed it down to when my web.xml file is added to the project. I had found a link through one of the many Google searches I did trying to solve this stating that a similar issue was because of the servlet tags in the web.xml file. I have copied in my web.xml file below:

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="Example_WS" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

I have tried everything I could think of and anything that seemed like it had a chance of working however none of this gave me any positive results. I hope that whatever is causing this error is something that is just glaringly obvious that I am just overlooking and it is a simple fix. Anything you all can contribute to this would be much appreciated!
