Refresh applet display in browser.

Question

I have a JSP file which has an applet in it. The applet displays the correct text when the JSP is loaded from the server onto the client.
public void paint(Graphics g) {
g.drawString("Hello blimp ! ", 15, 15);
When the screen loads in browser I see "Hello blimp" in the applet window.
Now I have a public method callMeSucker() in the applet which is called by a javascript function depending on certain action by user.
public void callMeSucker()
this.getGraphics().drawString("applet refreshed! ", 15, 15);
this.validate();
After the user action I dont see the applet window refreshed with this message "applet refreshed! " . I have alerts around this method call to the applet and they get displayed. This shows that the applet method call is withour error but why is the display not getting refreshed.
Thx

This is just a guess, but maybe it is working -- but then the GUI threads call paint() again, immediately overwriting the "applet refreshed!" message so fast that you can't see it. I guess you could call this a conflict between active and passive rendering.
If this is the case, you could fix it by having a field in the applet, say:
private String message = "Hello blimp ! ";
public void paint(Graphics g) {
  g.drawString(message, 15, 15);
public void callMeSucker() {
  message = "applet refreshed! ";
  repaint();
