Re: Unable to read Complex Types from Schema

[Michael Glavassevich <mr...@ca.ibm.com>]

Hi Venkat,

I see you're setting DOMImplementationRegistry.PROPERTY to 
com.sun.org.apache.xerces.internal.dom.DOMXSImplementationSourceImpl. 
That's a Sun repackaged fork of the Xerces codebase and probably very old 
now if it came from Java 5.0. Have you tried running this with an Apache 
version of Xerces? Xerces 2.8.0 is the most recent one.

Thanks.
