Description Samaresh Panda 2007-01-23 02:31:59 UTC 
This issue is a side-effect of fixing 92875 and 91333. In brief, CC now looks at
runtime catalog schemas if they are not found in the project catalog.

When it comes to web.xml kind of files, we try to do the same.
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
	 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
	 version="2.4">
...
</web-app>

The file http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd has been registered in
the catalog but the content is DTD and we get an NPE.

java.lang.NullPointerException

I think we should return either a null or status of the model as Invalid.

Comment 5 Nam Nguyen 2007-01-30 20:00:00 UTC 
The issue is that XDMAccess does not check for case that XDM returns DOM
Document with null element for a non-XML content.  The fix is simply check for
document element to avoid calling createRootComponent() with null argument.

Checked in trunk.  Patches in relesae551 attached.

Reviewed by Ayub.  Fix checked in release551.
Comment 7 Samaresh Panda 2007-02-07 06:12:50 UTC 
Works, the unit test is now part of the continuous build.
