Embed a 3rd-party JApplet in a Swing GUI & pass it parameters

Question

There\'s a third-party applet that I\'d like to embed in my Swing application. Basically, I\'d like it to be just another panel. This applet makes use of many parameters,

Answer 1

Implement an AppletStub & set it as the stub of the applet instance. E.G.

/*



*/
import java.applet.*;
import javax.swing.*;
import java.net.URL;
import java.util.HashMap;

public class ParamApplet extends JApplet {

    public void init() {
        String param = getParameter("param");
        System.out.println("parameter: " + param);
        add(new JLabel(param));
    }

    public static void main(String[] args) {
        ApplicationAppletStub stub = new ApplicationAppletStub();
        stub.addParameter(args[0], args[1]);
        ParamApplet pa = new ParamApplet();
        pa.setStub(stub);

        pa.init();
        pa.start();
        pa.setPreferredSize(new java.awt.Dimension(200,200));
        JOptionPane.showMessageDialog(null, pa);
    }
}

class ApplicationAppletStub implements AppletStub {

    HashMap params = new HashMap();

    public void appletResize(int width, int height) {}
    public AppletContext getAppletContext() {
        return null;
    }

    public URL getDocumentBase() {
        return null;
    }

    public URL getCodeBase() {
        return null;
    }

    public boolean isActive() {
        return true;
    }

    public String getParameter(String name) {
        return params.get(name);
    }

    public void addParameter(String name, String value) {
        params.put(name, value);
    }
}

Typical I/O

prompt>java ParamApplet param "apples & oranges"
parameter: apples & oranges

prompt>java ParamApplet param 42
parameter: 42
