Problem transforming XML/XSL Using Xalan

Question

Hi, I am using the xalan apis to transform XML/XSL in a servlet..My servlet code is like...
response.setContentType("text/html; charset=UTF-8");
// Output goes in the response stream.
PrintWriter out = response.getWriter();
boolean environmentOK = (new org.apache.xalan.xslt.EnvironmentCheck()).checkEnvironment (out);
try
TransformerFactory tFactory = TransformerFactory.newInstance();
// Get the XML input document and the stylesheet.
Source xmlSource = new StreamSource("D:\\DATA\\jrun\\test\\test.xml");
Source xslSource = new StreamSource("D:\\DATA\\jrun\\test\\test.xsl");
// Generate the transformer.
Transformer transformer = tFactory.newTransformer(xslSource);
// Perform the transformation, sending the output to the response.
transformer.transform(xmlSource, new StreamResult(out));
I am getting the error ..
javax.xml.transform.TransformerConfigurationException: javax.xml.transform.TransformerException: org.xml.sax.SAXException: Namespace not supported by SAXParserjavax.xml.transform.TransformerConfigurationException
That's why I have added the line..
boolean environmentOK = (new org.apache.xalan.xslt.EnvironmentCheck()).checkEnvironment (out);
But that gives me the following error diagnostic information...
ERROR.version.DOM=ERROR attempting to load DOM level 2 class: java.lang.NoSuchMethodException
I have put all the 3 required classes, xml-apis.jar, xercesImpl.jar and xalan.jar in my application servers classpath..
Please let me know what I am doing wrong..and how this can be fixed.
Thanks

hey Surajit
Your code is unable to create a transformer from a factory instance.
I would check why it is not creating the Transformer.On my win32 system i usee two forward slashes..to identify the file path
D://xyz//abc....instead of D:\\...i wonder if thats one reason why your code is not able to create a transformer based on the StreamSource u create for the file paths.
Code i use..that works
javax.xml.transform.TransformerFactory tFactory =
                                                            javax.xml.transform.TransformerFactory.newInstance();
                                                  javax.xml.transform.Source xmlSource = new javax.xml.transform.stream.StreamSource                              (xmlInputSource);
                                             javax.xml.transform.Source xslSource = new javax.xml.transform.stream.StreamSource
                                   (xslInputSource);
                                                                                                    // Generate the transformer.
                                                            javax.xml.transform.Transformer transformer = tFactory.newTransformer(xslSource);
                                                                                               // Perform the transformation, sending the output to the response.
                                                            transformer.transform(xmlSource,new javax.xml.transform.stream.StreamResult(out));
                                                                                                    I used jaxp-1.2 with tomcat 4.1.12
Hope that helps.
