Dear Sirs,
I have a simple problem: retrieving data from a web-server via a
proxy-server from within an applet. There are no properties for
proxy support in classes URL, URLConnection,... How can I set proxy
parameters in an applet? I tried the following example, but it didn't
work:

<begin
import java.awt.*;
import java.applet.*;
import java.io.*;
import java.net.*;

public class URQ2 extends Applet {

public void init() {
super.init();

//{{INIT_CONTROLS
setLayout(null);
addNotify();
resize(426,266);
setBackground(new Color(12632256));
textUrl = new java.awt.TextField();
textUrl.reshape(24,12,382,26);
add(textUrl);
textArea = new java.awt.TextArea();
textArea.reshape(24,48,379,193);
add(textArea);
//}}
}

public boolean handleEvent(Event event) {
return super.handleEvent(event);
}

public boolean action(Event e, Object o) {
        if (e.target == textUrl) {
            URL baseu;
            URL u;
            try {
                baseu = new URL("http://140.13.8.220:8080/");
            }
            catch (MalformedURLException me) {
textArea.appendText("Malformed baseURL: http://140.13.8.220:8080/");
                return true;
            }
            
            try {
                
u = new URL(baseu, textUrl.getText());
     /*URLConnection connection = u.openConnection();
     PrintStream outStream = new PrintStream(connection.getOutputStream());
                outStream.println("GET http://www.microsoft.com/ HTTP/1.0" + "\n");
                outStream.close();
*/
                DataInputStream inStream = new DataInputStream(new BufferedInputStream(u.openConnection().getInputStream()));
                String inputLine;

                while ((inputLine = inStream.readLine()) != null) {
                    textArea.appendText(inputLine);
                }
                inStream.close();
}
catch(MalformedURLException me) {
    textArea.appendText("Malformed URL: " + me.toString());
}
catch(IOException ioe) {
                textArea.appendText(ioe.toString());
}
return true;
        }
else
return false;
    }
    
//{{DECLARE_CONTROLS
java.awt.TextField textUrl;
java.awt.TextArea textArea;
//}}
}
end>

In VisualBasic I have a control with proxy properties and it works fine.

I'm very interested about your answer!

Yours very truly
