I have a BIRT reports that runs properly on Jboss 4.0.3SP1. When we try to run the same report on weblogic 10.3, I get this error:

This looked like an XML parsing issue. I had used the webviewerexample as my template and the basic report had run fine on Weblogic.
I am using this setup in weblogic-application.xml
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-application xmlns="

I compared the system properties settings between jboss and weblogic and saw some differences but I am not sure which entries matter. I have attached the system properties used by both jboss and weblogic.
Any help will be appreciated.
Mahesh.
