Performing XSL Transformations

<%@ page language="java" contentType="text/html" %>
<%@ page pageEncoding="UTF-8"%>
<%@ page import="javax.xml.transform.*"%>
<%@ page import="javax.xml.transform.stream.*"%>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Customer Orders</title>
  </head>
  <body>
    <h1>Customer Orders</h1>
      <%! String FS = System.getProperty("file.separator"); %>
        <%
        String xmlFile = request.getParameter("XML");
        String xslFile = request.getParameter("XSL");
        String ctx = getServletContext().getRealPath("") + FS;
        xslFile = ctx + xslFile;
        xmlFile = ctx + xmlFile;
        TransformerFactory tFactory =
          TransformerFactory.newInstance();
        Transformer transformer =
          tFactory.newTransformer(new StreamSource(xslFile));
        transformer.transform(
          new StreamSource(xmlFile), new StreamResult(out));
        %>

XML transformation

<%@ page import="javax.xml.transform.*, javax.xml.transform.stream.*, java.io.*" %>
<% 
    try 
    {  
        TransformerFactory transformerfactory = TransformerFactory.newInstance(); 
        Transformer transformer = transformerfactory.newTransformer(new StreamSource(new File    
            (application.getRealPath("/") + "your.xsl")));
        transformer.transform(new StreamSource(new File(application.getRealPath("/") + "your.xml")), 
        new StreamResult(new File(application.getRealPath("/") + "your.html")));
    }
    catch(Exception e) {}  
    FileReader filereader = new FileReader(application.getRealPath("/") + "your.html");
    BufferedReader bufferedreader = new BufferedReader(filereader);
    String instring;
    while((instring = bufferedreader.readLine()) != null) { 
%>
        <%= instring %>
<%
        }
        filereader.close();
