AppletContext sample

Anyone out there have an example of an applet which uses the AppletContext stuff to load a URL into a new browser window? I've been banging my head against this to no avail and would like to see some source from someone who has either done it or has one of those phone-book size Java manuals with a handy example to plagiarize.

100 points for a quick sample.


TIA

Marty

getAppletContext().showDocument(url, "XXX")

Here xxx is the target frame.
Since there is no frame at all, it will open a new window

url is the url U have to give in the format

http://yourserver:serverport/file

Hi Ravindra,

Can you post some actual applet code? I got this much from the Java Doc already.

Do I have to implement the AppletContext interface or something?

Some actual working source is what I'm really after. Please assume ignorance on my part!

If your program is an applet, it already has a valid AppletContext and ravindra76's example is actually a piece of code.

Cheers,

Dear friend,


if(e.getSource()==b1)
{
try{
URL url=new URL("http://www.yoursite.com/your.html");
}
catch(MalformedURLException e){}
getAppletContext().showDocument(url,"_blank");
}
will work properly
Don't forget to modify the code as per your need.

Run this code as

Jump.html :-

Note: put this jump.html and Jump.class in ur webserver document root.

for me it is http://localhost/jump.html

<HTML><HEAD></HEAD><BODY>
 <APPLET CODE="Jump.class"
         HEIGHT=100
         WIDTH=300>
 </APPLET></BODY></HTML>

Jump.java


import java.awt.*;
import java.applet.*;
import java.net.*;

public class Jump extends Applet {
      Button btnJump;

      public void init() {

            btnJump = new Button("JUMP To");
            add(btnJump);
      }
      public boolean action(Event e,Object o) {

            if ( e.target.equals(btnJump)) {
                  try {
                  getAppletContext().showDocument(new URL("http://www.yahoo.com"),"xxx");
                  }
                  catch ( Exception ee) {
                        System.out.println("Malformed URL");
                  }
            }
            return false;

      }
}
