Naveen: it doesn't look like you ever got a reply (probably because of the holidays) ... did you ever manage to get things working?
looking over your question, the root problem seems to be related to the the XPath Factories that should come standard in tomcat. I have never seen this error before, but googling for it turned up this page... http://www.psuedoguru.com/roller/page/psuedoblog?entry=failed_to_create_an_xpathfactory ...which suggests that this can happen if you have Tomcat JDK1.4 compatibility libraries installed, and then you upgrade to 1.5 : Caused by: java.lang.RuntimeException: XPathFactory#newInstance() failed : to crea : : te an XPathFactory for the default object model: : http://java.sun.com/jaxp/xpath/ : : dom with the XPathFactoryConfigurationException: : javax.xml.xpath.XPathFactoryCon : : figurationException: No XPathFctory implementation found for the object : model: h : : ttp://java.sun.com/jaxp/xpath/dom -Hoss
