XMLBeans - xsi:type stripped using Axis2 and Tomcat?

Question

I’m new to XMLBeans and have been trying to use it to create an XML document as part of an axis2 web service. When I run my code as a standard Java application or as a standard servlet, the XML is correctly generated:

<?xml version="1.0" encoding="UTF-8"?>
<c:BroadsoftDocument protocol="OCI" xmlns:c="C">
<sessionId>000000001</sessionId>
<command xsi:type="AuthenticationRequest" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"&gt;
<userId>admin</userId></command>
</c:BroadsoftDocument>

However, when the exact same code is run under Axis2 & Tomcat in a servlet I get:

<?xml version="1.0" encoding="UTF-8"?>
<c:BroadsoftDocument protocol="OCI" xmlns:c="C">
<sessionId>000000001</sessionId>
<command>
<userId>admin</userId></command>
</c:BroadsoftDocument>

This of course isn’t valid – the xsi:type of the “command” element is stripped when the code is run under Tomcat.

Does anyone have any suggestions of what I could be doing wrong that would cause this type of issue only when running under Axis2? At first I thought it was a Tomcat issue, but after creating a generic servlet and running the exact same code I don't have any issues. I've tried playing with the XMLOptions for XMLBeans, but couldn't seem to resolve the problem. The options I'm currently using are:

xmlOptions = new XmlOptions();
xmlOptions.setCharacterEncoding("UTF-8");
xmlOptions.setUseDefaultNamespace();
xmlOptions.setSaveAggressiveNamespaces();
xmlOptions.setSavePrettyPrint();

It turn out the issue is with the class loader order that Axis2 uses. This was patched and the functionality is described here:

Long story short, to resolve this issue you need to edit the "services.xml" for your Axis2 project and add:

<parameter name="ServiceTCCL">composite</parameter>
