You can tell the runtime which SaxParserFactory implementation to use in a number of ways, such as setting the |javax.xml.parsers.SAXParserFactory system property.| The xmlparsev2.jar probably contains a |META-INF/services/javax.xml.parsers.SAXParserFactory file.| See the method detail for the newInstance static factory method for more information: http://java.sun.com/j2se/1.4.2/docs/api/javax/xml/parsers/SAXParserFacto ry.html Adam Adari, Chandra wrote: > Thanks Duane. > > I did some more research and found out that oracle "xmlparsev2.jar" is > causing the issue.
