This is because you might be using older version of xalan, xerces jars. Try to update the latest versions of these jars.I did not tried with this approach. My approch i s: create a folder in jrehome\lib folder with name "endorsed" and put the following jars in it. 1. xalan.jar 2. xercesImpl.jar 3. xml-apis.jar. It works for me.
