JSP store data entered by user into XML file

1)form.jsp:

<html>
<form method="post" action="createxml.jsp">
<table>
<tr><td>Name:</td><td><input type="text" name="name"></td></tr>
<tr><td>Address:</td><td><input type="text" name="address"></td></tr>
<tr><td>Contact No:</td><td><input type="text" name="contact"></td></tr>
<tr><td>Email:</td><td><input type="text" name="email"></td></tr>
<tr><td></td><td><input type="submit" value="Submit"></td></tr>
</table>
</form>
</html>

2)createxml.jsp:

<%@page import="java.io.*,org.w3c.dom.*,javax.xml.parsers.*,javax.xml.transform.*, javax.xml.transform.dom.*,javax.xml.transform.stream.*"%>  

  <%!
        public void createXmlTree(Document doc,String name,String address,String contact,String email) throws Exception {
        System.out.println(name);
        Element root = doc.createElement("Employee");
        doc.appendChild(root);

        Element child1 = doc.createElement("Name");
        root.appendChild(child1);

        Text text1 = doc.createTextNode(name);
        child1.appendChild(text1);

        Element child2 = doc.createElement("Address");
        root.appendChild(child2);

        Text text2 = doc.createTextNode(address);
        child2.appendChild(text2);

        Element child3 = doc.createElement("ContactNo");
        root.appendChild(child3);

        Text text3 = doc.createTextNode(contact);
        child3.appendChild(text3);

        Element child4 = doc.createElement("Email");
        root.appendChild(child4);

        Text text4 = doc.createTextNode(email);
        child4.appendChild(text4);

        TransformerFactory factory = TransformerFactory.newInstance();
        Transformer transformer = factory.newTransformer();

        transformer.setOutputProperty(OutputKeys.INDENT, "yes");

        StringWriter sw = new StringWriter();
        StreamResult result = new StreamResult(sw);
        DOMSource source = new DOMSource(doc);
        transformer.transform(source, result);
        String xmlString = sw.toString();

        File file = new File("c:/emp.xml");
        BufferedWriter bw = new BufferedWriter(new FileWriter(file));
        bw.write(xmlString);
        bw.flush();
        bw.close();

    }%>
<%
      String name=request.getParameter("name");
      String address=request.getParameter("address");
      String contact=request.getParameter("contact");
      String email=request.getParameter("email");
  try{
      System.out.println(name);
      DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
      DocumentBuilder docBuilder = builderFactory.newDocumentBuilder();
      Document doc = docBuilder.newDocument();
      createXmlTree(doc,name,address,contact,email);

      out.println("<b>Xml File Created Successfully</b>");
  }
  catch(Exception e)
  {
    System.out.println(e);
  }     
  %>
