1)how above form parameters like radio button data,drop down menu data can be transfered to the servlet(I mean can I get it using request.getparameter(); or any other way to get this data from the form to a servlet & then to display it ajsp page?

If an input has just one value (eg: radio button), you can simply get it using getParameter(). For getting multiple values (eg: check boxes), have a look at HttpServletRequest.getParameterValues(String).

Thanks Devaka Cooray ,i'll upload my AddServlet(below). Which is the one having the(Servlet) code for run the application with a created mysql database.but this code compiles successfully, but doesn't add values to the database(I created database correctly,can you help to solve this problem?

package src;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import util.JDBC;

/**

 */
public class AddServlet extends HttpServlet {

@Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        String name=request.getParameter("name");
        String sex=request.getParameter("sex");
        String year=request.getParameter("year");
        String month=request.getParameter("month");
        String day=request.getParameter("day");
        String address=request.getParameter("address");
        String tel1=request.getParameter("tel1");
        String tel2=request.getParameter("tel2");

Connection con=JDBC.getConnection();
        String sql="INSERT INTO contacts VALUES('" + name +"','" +sex + "','" +
                year + "','" + month +"','" +day +"','"+address + "','" + tel1 +"','" +tel2 +"')";

try{
        Statement stmt=con.createStatement();
        stmt.execute(sql);
    } catch(SQLException ex){
    ex.printStackTrace();

}
response.sendRedirect("success.jsp") ;
    }

}

Have you checked the server log for the problem cause? What has happened should have logged down there.

Beside your database problem, pay attention on....

- Invoking JDBC codes directly from your servlet class is not a good practice. You should have separate classes for database access.
- Storing the inputs without having proper validations is inherently insecure and prone to SQL injection attacks.

Thanks Devaka Cooray,
Is it my servlet codes are right?I mean the request.getParameter() values to get form data?

Yep!
