XML : TransformerConfigurationException

Question

hi all,
When ever I execute following servlet I get following Exception
javax.xml.transform.TransformerConfigurationException : NameSpace not supported by SAXParser
same code will execute OK from command line as an application.
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.apache.xerces.parsers.DOMParser;
import java.io.*;
public class TransformProduct extends HttpServlet {
public void doGet (HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
String XMLSource = "C:/xml_java/basic/products.xml";
String XSLSource = "C:/xml_java/basic/product.xsl";
response.setContentType("text/html");
PrintWriter output = response.getWriter();
try{
TransformerFactory transformerFactory =
TransformerFactory.newInstance();
FileReader reader = new FileReader(XSLSource);
//Following line generate the Exception
Transformer transformer = transformerFactory.newTransformer(
new StreamSource(reader));
DOMParser parser = new DOMParser();
parser.parse(XMLSource);
Document document = parser.getDocument();
catch(javax.xml.transform.TransformerConfigurationException tce)
errString = "tce "+tce.getMessage();
catch(Exception e)
errString = "e "+e.getMessage();
e.printStackTrace();
System.out.println(errString);
}//doGet Ends
}//Class Ends
Here is the CLASSPATH settings:
SET CLASSPATH=.;c:\xalan\bin\xerces.jar;c:\xalan\bin\xalan.jar;
SET CLASSPATH=%CLASSPATH%;c:\tomcat\lib\webserver.jar;c:\tomcat\lib\jasper.jar;
SET CLASSPATH=%CLASSPATH%;c:\tomcat\lib\xml.jar;c:\tomcat\lib\servlet.jar;c:tomcat\lib\tools.jar;
I am using xalan-j_2_0_1
Any help will be great !!!
Cheers,
SUNIL

HI.
I've gotten that exception before. I wasn't using a servlet at the time...and I really don't know why it runs fine from the command line, but to get rid of the exception, I changed some element names inside the xml file. This might be a pain cause you might have to reconfigure your parser.
