Hi Sagara, I see two issues. The first Mukul already pointed out. "http://www.w3.org/ns/wsdl";, "http://www.w3.org/ns/wsdl-extensions"; and "http://www.w3.org/2001/XMLSchema"; are not schema documents. I suppose these are the target namespaces of the other documents you have in the list. They just happen to resolve to HTML pages on the W3C site. Do not include them here. SchemaFactory only takes schema documents as input.
Your other issue is that you're not actually using Xerces (despite your intentions to do so). The com.sun.org.apache.xerces.* classes are Sun's (aging) fork of the Xerces codebase which they develop/maintain and release in their JDK. It has bugs which are unique to it and others which have long been fixed in Apache. One bug [1] in some versions of the JDK prevents Xerces' SchemaFactory implementation from being loaded normally. You probably got Sun's implementation of SchemaFactory due to this bug. Using the Endorsed Standards Override Mechanism [2][3] (with xml-apis.jar and xercesImpl.jar) will resolve that. Thanks.
