This is the servlet code:
package com.example.web;
import com.example.model.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class BeerSelect extends HttpServlet{
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException{
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("Beer Selection Advice<br>");
String c = req.getParameter("COLOR");
BeerExpert be = new BeerExpert();
List result = be.getBrands(c);
req.setAttribute("styles", result);
RequestDispatcher view = req.getRequestDispatcher("result.jsp");
view.forward(req, res);
}
}
And this is my DD:
