I have an Applet which receive data packets and MUST display images from the received data.
All stuff is done except the image displaying.
The data is a complete jpeg file.
It would be easy to write a file, but the applet security doesnt allow this since i dont have and dont plan to buy a signature.

Is there another way to do this?
If you have please send me an working sample code.

Thanks

What does it mean to be "Always On"?

Works pretty fine. Thanks a lot.

By the way do you know how to force a immediate repaint of canvas?

I'm trying to use the following code but repaint occurs eventually, not in all calls.

Graphics g = getGraphics();
if (g != null)
{
update(g);
}

Why not just call repaint?

repaint does not execute a repaint at the time of call, seems it waits until its event to be processed later, in this situation i call repaint in a loop and nothing happens until i move or resize window.
