Hi Subin, you have a very old xerces version, I did not even find it in the archives of the xerces homepage ;-). So I cannot check what files it contains. Hopefully you have the xerces download package somewhere and can check what JARs it contains. I found a 2.6.2 on my machine, and this contained xmlParserAPIs.jar, xml-apis.jar, xercesSamples.jar, xercesImpl.jar and resolver.jar. So all of those should be removed.
