Question

I am trying to attach a parameter to a URL on a servlet:

<a href="another_servlet?myVariable=<%=thevariable>> Go to this </a>

to be retrieved as a variable on another servlet that is called.

which contains the following code :

// Database access with a servlet
package ubiserv.simple;

import java.io.*;
import java.util.*;
import javax.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class Product extends HttpServlet {
public void service(HttpServletRequest request,HttpServletResponse response)
        throws IOException, ServletException{

        response.setContentType("text/html");
        PrintWriter out = response.getWriter();

---

It seems that I can use this code to fetch what I need

request.getAttribute

but I have searched almost everywhere and I cannot figure out how to put it all together. Thanks in advance.

No, those are query parameters. Use this to get that value:

String myVariable = request.getParameter("myVariable");

Check the javadocs:
