error while using SAX parser.

[Muthuramu, Suganthi \(Cognizant\)]

Hi,               I am getting the following error, when I try to upgrade the version to xalan 2.7.0. I am using the xml-apis.jar and xercesImpl.jar that comes along with the xalan2.7.0. The Java version is 1.4.2_08 and I am using jdom b7.   The below code works fine with standalone java application, but if this code is deployed in iplanet webserver, I am getting this error, java.lang.RuntimeException: Error in building: SAX2 driver class org.apache.xerces.parsers.SAXParser does not implement XMLReader                 InputStream istream = getClass().getResourceAsStream("stylesheet.xsl");                         StringWrite soapMessage = new StringWriter();                         TransformerFactory tFactory = TransformerFactory.newInstance();                         StreamSource ss = new StreamSource(istream);                         Transformer transformer = tFactory.newTransformer(ss);                         sr = new StringReader(response);                         transformer.transform(new StreamSource(sr), new StreamResult(soapMessage));                 Could you please help me to solve this issue? Where else I need to include the new jars apart from the classpath?       Regards Suganthi Muthuramu
