and my servlet code are:-
import java.io.*;
public class invoice extends javax.servlet.http.HttpServlet {
// Respond to HTTP GET requests from browsers.
public void service (javax.servlet.ServletRequest request,
javax.servlet.ServletResponse response)
throws javax.servlet.ServletException, java.io.IOException
{
// Set content type for HTML.
response.setContentType("text/html; charset=UTF-8");
// Output goes to the response PrintWriter.
java.io.PrintWriter out = response.getWriter();
File fo1 = new File("/home/darryl/invoice.xml");
File fo2 = new File("/home/darryl/invoice.xsl");
try
{
javax.xml.transform.TransformerFactory tFactory =
javax.xml.transform.TransformerFactory.newInstance();
// Get the XML input document and the stylesheet, both in the servlet
// engine document directory.
javax.xml.transform.Source xmlSource =
new javax.xml.transform.stream.StreamSource(fo1);
// (new
// FileInputStream("/home/osbmaster/www/invoice/invoice.xml"));
javax.xml.transform.Source xslSource =
new javax.xml.transform.stream.StreamSource(fo2);
// (new
// FileInputStream("/home/osbmaster/www/invoice/invoice.xsl"));
// 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));
}
// If an Exception occurs, return the error to the client.
catch (Exception e)
{
out.write(e.getMessage());
e.printStackTrace(out);
}
// Close the PrintWriter.
out.close();
}
}

Can anybody tell me wat's wrong with the servlet code above?
