            DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
            DocumentBuilder builder = factory.newDocumentBuilder();
            Document doc = builder.newDocument();
            Element results = doc.createElement("cpa");

            String userName = "root";
            String password = "";
            String url = "jdbc:mysql://localhost/masdata";
            Connection conn = DriverManager.getConnection(url, userName, password);
            Statement stmt = conn.createStatement();
            String cpa_idd = request.getParameter("cpa_id");
            String algm = request.getParameter("algo");
            String priorityy = request.getParameter("priority");

            ResultSetMetaData rsmd = rs.getMetaData();

            while (rs.next()) {

                for (int i = 1; i <= colCount; i++) {
                    String columnName = rsmd.getColumnName(i);
                    Object value = rs.getObject(i);
                    Element node = doc.createElement(columnName);

            DOMSource domSource = new DOMSource(doc);
            TransformerFactory tf = TransformerFactory.newInstance();
            Transformer transformer = tf.newTransformer();
            transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
            transformer.setOutputProperty(OutputKeys.METHOD, "xml");
            transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
            StreamResult sr = new StreamResult("C:/Users/Shruthi/Documents/NetBeansProjects/WebApplication6/web/cpa.xml");
            transformer.transform(domSource, sr);

            doc = builder.parse("C:/Users/Shruthi/Documents/NetBeansProjects/WebApplication6/web/cpa.xml");

  public boolean isTextNode(Node n){
    return n.getNodeName().equals("#text");
    <h2><font color='lilac'>CP Agent</font></h2>

    <table border="2">
          Element  element = doc.getDocumentElement();
          NodeList personNodes = element.getChildNodes();
          for (int i=0; i<personNodes.getLength(); i++){
            Node emp = personNodes.item(i);
            if (isTextNode(emp))
            NodeList NameDOBCity = emp.getChildNodes();
          for (int j=0; j<NameDOBCity.getLength(); j++ ){
            Node node = NameDOBCity.item(j);
            if ( isTextNode(node))
            Node firstChild = node.getFirstChild();
String textnode;
if (firstChild == null) textnode = null;
else textnode = firstChild.getNodeValue();
        <td><%= textnode %></td>

and my xml file is below.


It Works fine till doc = builder.parse("C:/Users/Shruthi/Documents/NetBeansProjects/WebApplication6/web/c­pa.xml");

Move all computation stuff connection to DB and building XML to servlet. These tasks do not belong to JSP/page view. You do so and you will find your life easier on debugging
