Get host url from Java Applet

I have a java applet which is hosted on a device's web page. The applet needs to retrieve data from the device at runtime. Currently the device is configured to output the required data out port 8080 (so, say, 192.168.1.1:8080). How would I inform my applet of its host web page's URL so that it would know where to get the data from?

Thanks, John

Use Applet#getCodeBase(). This method returns the URL of the directory which contains this applet.

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

public class FromWhere extends Applet {
  public void init() {
    Label label = new Label(getCodeBase().toString());
    add(label);
 }
}

Note : NULL is returned if the applet is loaded from the file system since JDK1.7b25

You can use Applet#getDocumentBase()
