That's an interesting question. The short answer is, you can't. For one, the APPLET tag is ignored by the Swing HTML parser. Then, I'm not sure, what happens if you embedd heavy-weight components like applets into an editor pane.
However, you can use  JEditorPane e = new JEditorPane();
  e.setText("Hallo, Welt");
  e.setCaret(5);
  e.insertComponent(new JButton("Click me"));to add swing components to your text. So you might be able to create a working solution based on this foundation.
I can imagine two approaches. You could either create your own applet-like JEditorPanelets which would be basically JPanels with some glue code to allow the the panelet to access its editorPane.
Or you could explore the approach to add a heavy weight applet and write a compatiblily stub. Here's an outline  class AppletAwareEditorPane extends JEditorPane {
    List applets;
    MyAppletStub stub;
    public void insertApplet(Applet a) {
      applets.add(a);
      a.setStub(stub);
      a.init();
    public void startApplets() {
      Iterator i = applets.iterator();
      while(i.hasNext()) ((Applet)i.next()).start();
    }However, each applet would require to run in its own tread and I'm pretty sure this would break swing as it is not thread save.
