problem in servlet to jsp

My servlet is supposed to create an instance of database object using MySql which would be passed to showperson.jsp to show the information saved in the table. But this doesnot show any result just a blank page.

package controller;
import vu.*;
import java.io.*;
import java.net.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ControllerServlet extends HttpServlet {

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
      searchPerson(request,response);
    }

@Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

@Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

@Override
    public String getServletInfo() {
        return "Short description";
    }// </editor-fold>
protected void searchPerson(HttpServletRequest request,HttpServletResponse response) throws
        ServletException, IOException{
        try{
            personDAO pDAO= new personDAO();
        String pName= request.getParameter("name");
        ArrayList personList = pDAO.retrievePersonList(pName);
        RequestDispatcher rd=getServletContext().getRequestDispatcher("showperson.jsp");
        request.setAttribute("plist",personList);
        rd.forward(request,response);
        }
        catch(Exception ex){
        System.out.println("Exception is" + ex);
        }
}
}
This is not going to showperson.jsp
Code of showperson.jsp is:

<%@page import= "java.util.*"%>
<%@page  import="vu.*" %>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
         <h2>Address Book</h2>
        <table border="1">
           <tbody>
                <tr>
                    <th>Name</th>
                    <th>Address</th>
                    <th>Phone Number</th>
                </tr>

<%
        ArrayList personList=(ArrayList)request.getAttribute("plist");
        PersonInfo person = null;
        for(int i=0;i<personList.size();i++){
            person=(PersonInfo)personList.get(i);
            request.setAttribute("p",person);
        %>

<tr>
                    <td>${p.name}</td>
                    <td>${p.address}</td>
                    <td>${p.phoneNum}</td>
                </tr>
           </tbody>
        <%
        }
        %>
        </table>

</body>
</html>

Code of personDAO class is as follows:-
package vu;

import java.util.*;
import java.sql.*;
/**
 *
 * @author Narjis Raza
 */
public class personDAO {

/*    private static class personList {

public personList() {
        }*/
    
private Connection con;
public personDAO()throws ClassNotFoundException, SQLException{
    establishConnection();
}
private void establishConnection()throws ClassNotFoundException,SQLException
    {
    Class.forName("com.mysql.jdbc.Driver");
    String conURL="jdbc:mysql://localhost:3306/practice";
    con=DriverManager.getConnection(conURL);
    }
public ArrayList retrievePersonList(String pName)throws SQLException{
    ArrayList personList = new ArrayList();
    String sql = "SELECT * FROM Person WHERE name=?";
    PreparedStatement pStmt=con.prepareStatement(sql);
    pStmt.setString(1, pName);
    System.out.println("retrieve person list");
    ResultSet rs = pStmt.executeQuery();
    String name;
    String add;
    int pNo;
    while (rs.next()){
    name=rs.getString("name");
    add=rs.getString("address");
    pNo=rs.getInt("PhoneNum");
    PersonInfo PI=new PersonInfo();
    PI.setName(name);
    PI.setAddress(add);
    PI.setPhoneNum(pNo);
    personList.add(PI);
    }
    return personList;

}

public void finalize(){
try{
    if(con!=null){
    con.close();
    }
    }catch(SQLException sex){
    System.out.println(sex);
    }
}
}

Please take care to reply rather than start new topics when continuing to address the same question. I locked the original post so we can continue here.

Did you get any exception in the server side?

No i did'nt get any exception but i ma unable to debug it line by line can you tell me how to debug and add watches in Netbeans 6.9

I would start by writing to a log file the number of items in personList immediately after line 37 in the servlet - perhaps it really is empty.
