Projects. Customizing your servlet entry point.

In class we talked about the projects and then developed this: 

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
              
public class Chat extends HttpServlet {

  public void doGet(HttpServletRequest req, 
                    HttpServletResponse resp) 
              throws ServletException, 
                     IOException 
  { 
     resp.setContentType("text/html"); 
     resp.getWriter().println(

         "<html><head><title>L19_S3 GET</title></head><body bgcolor=white>"
       + "<form method=POST action=/examples/servlet/Chat>Type your name here: " 
       + "<input type=text name=namefield size=10> <p> then push <input " 
       + " type=submit value=Proceed> (or hit Enter) </form></body></html>"

     ); 

  } 

  public void doPost(HttpServletRequest req, 
                     HttpServletResponse resp) 
              throws ServletException, 
                     IOException 
  {
     resp.setContentType("text/html"); 
     resp.getWriter().println(
           
         "<html><body bgcolor=white><h1>Hello, <font color=blue>" 
       + req.getParameter("namefield") 
       + "</font>!</h1>" 
       + "  <applet code=ChatApplet " 
       + "codebase=\"http://burrowww.cs.indiana.edu:12000/chat\"" 
       + "               width=400 height=400> " 
       + "       <param name=user value=\"" 
       + req.getParameter("namefield") 
       + "\"> " 
       + " </applet>" 
       + " </body></html>"

     ); 

  } 
       

}
Then we also talked about applets.
