You'll need to convert the applet's canvas into a bitmap, convert the bitmap into JPEG or GIF format, then send the bitmap in a binary file transmission to the server. The server really can't do anything but catch the file - all the work has to be done on the client.
As far as getting the bitmap and converting it to image file format, I recommend you ask in the AWT/Swing forum.
For object-oriented drawing, you might find it better to render the objects from a list of graphics objects in the applet and transmit the list as a file - this is actually preferable if some other user would be viewing the graphics later, as different users may have different screen resolutions. The downside is that there's no real standard builtin to browsers for object-oriented image display, so you'd have to use a display applet.
