1)Servlet.java

import java.io.*;
    import java.sql.*;
    import java.util.*;
    import javax.servlet.*;
    import javax.servlet.http.*;

    public class Servlet extends HttpServlet{
        protected void doPost(HttpServletRequest req, HttpServletResponse res)
            throws ServletException, IOException{

    ArrayList list=new ArrayList();
    try{
         Class.forName("com.mysql.jdbc.Driver");
               Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "root");
               Statement st=con.createStatement();
               ResultSet rs=st.executeQuery("select * from employee");
               while(rs.next()){
                   list.add(rs.getString("name"));
                   list.add(rs.getString("address"));
                   list.add(rs.getString("contactNo"));
                   list.add(rs.getString("email"));
    }
    req.setAttribute("data", list);
            RequestDispatcher rd = req.getRequestDispatcher("/jsp/data.jsp");
            rd.forward(req, res);
    }
    catch(Exception e){
    }
        }
    }

2)data.jsp:

<%@page language="java" import="java.util.*" %>
<html>
<body> 
<table border="1" width="303">
<tr>
<td width="119"><b>Name</b></td>
<td width="168"><b>Address</b></td>
<td width="119"><b>Contact no</b></td>
<td width="168"><b>Email</b></td>
</tr>
<% Iterator itr;%>
<% List data=(List)request.getAttribute("data");
for(itr=data.iterator(); itr.hasNext(); ){
%>
<tr>
<td width="119"><input type="text" value=<%=itr.next()%>></td>
<td width="168"><input type="text" value=<%=itr.next()%>></td>
<td width="168"><input type="text" value=<%=itr.next()%>></td>
<td width="168"><input type="text" value=<%=itr.next()%>></td>
</tr>
<%}%>
</table>
</body>
</html>
