Hi,
I am trying to write a very simple communication between an
applet and a servlet, based on an example I've seen on the Sun
site. However, it is not working properly. I am running a JSDK2.1
server, and I think the problem is in my applet, because I dont
think I give it a proper URL to the servlet, although it seemed
to me that I tried all the variations. The applet and servlet
classes are in the same directory, if that helps. Anyway, if you
guys could look at my code and tell me whats wrong, I would
greatly appreciate it.

import java.applet.*;
import java.net.*;
import java.io.*;
import java.awt.*;
public class TestApplet extends Applet
{
private String line;

public void init () {
    try {
        URL url = new
URL("http://localhost:8080/webpages/Web-inf/servlets/TestServlet?
name=TestApplet");
        BufferedReader in = new BufferedReader(new
InputStreamReader(url.openStream()));
        line = in.readLine();
        in.close();
    }
    catch (Exception e){e.printStackTrace();}
}

public void paint (Graphics g) {
     g.drawString (line, 20, 40);
     g.drawString("This is just applet drawing!", 20, 80);
}
}// testapplet

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

public class TestServlet extends HttpServlet {

public void doGet(HttpServletRequest req,
            HttpServletResponse res) throws ServletException,
IOException
{
    res.setContentType ("text/plain");
    PrintWriter out = res.getWriter();
    out.println ("Hello " + req.getParameter("name") + ", servlet
talking!");
    out.close();
}
}// testservlet

Thanks,
Val.
