Hello Friend,

Try the following code:

1)callServlet.html:

<html>
<center><h3>Registration Form</h3></center>
<form method="post" action="http://localhost:8080/examples/Registration">
<center>
<table>
<tr><td>ID:</td><td><input type="text" name="userId" size="20"></td></tr>
  <tr><td>First Name:</td><td><input type="text" name="firstname" size="20"></td></tr>
  <tr><td>Last Name:</td><td><input type="text" name="lastname" size="20"></td></tr>
    <tr><td>Email:  </td><td><input type="text" name="email" size="20"></td></tr>
  <tr><td>City:    </td><td><input type="text"  name="city" size="20"></td></tr>
  <tr><td>State:     </td><td><input type="text" name="state" size="20"></td></tr>
  <tr><td>Country:    </td><td> <input type="text" name="country" size="20"></td></tr>
  <tr><td><input type="submit" value="Submit" name="B1"></td><td><input type="reset" value="Reset" name="B2"></td></tr>
  </table>
  </center>
</form>
</html>

2)Registration.java:

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

public class Registration extends HttpServlet{
  public void init(ServletConfig config) throws ServletException{
  super.init(config);
  }
    public void doPost(HttpServletRequest req, HttpServletResponse res) 
    throws ServletException, IOException{
    String connectionURL = "jdbc:mysql://localhost:3306/test";
    Connection connection=null;
    ResultSet rs;
    res.setContentType("text/html");
    PrintWriter out = res.getWriter();
    String uId = req.getParameter("userId");
    String fname = req.getParameter("firstname");
    String lname = req.getParameter("lastname");
    String email = req.getParameter("email");
    String state = req.getParameter("state");
    String city = req.getParameter("city");
    String country = req.getParameter("country");
    try{
    Class.forName("com.mysql.jdbc.Driver");
    connection = DriverManager.getConnection(connectionURL, "root", "root"); 
    String sql = "insert into employee(empid,firstname,lastname,email,state,city,country) values (?,?,?,?,?,?,?)";
    PreparedStatement pst = connection.prepareStatement(sql);
    pst.setString(1, uId);
    pst.setString(2, fname);
    pst.setString(3, lname);
    pst.setString(4, email);
    pst.setString(5, state);
    pst.setString(6, city);
    pst.setString(7, country);
    int numRowsChanged = pst.executeUpdate();
    out.println("Hello:");
    out.println("'"+fname+"'");
    pst.close();
    }
    catch(Exception e){
    out.println(e);
    }
   }
}

3)Do the servlet mapping in web.xml:

<servlet>
        <servlet-name>Registration</servlet-name>
        <servlet-class>Registration</servlet-class>
    </servlet>
<servlet-mapping>
        <servlet-name>Registration</servlet-name>
        <url-pattern>/Registration</url-pattern>
    </servlet-mapping>

Thanks
