What kind of data do you want to watermark? An image? Sound? The Java
source?

And where are your problems? Reading the image/sound-file? Applying the
mark? Saving the data in a certain format?

Perhaps the ImageIO-package might help you...

Ciao,
Ingo

I think the OP is indicating a (rumored) watermarking process (as in,
code security, not image). If so, I have no knowledge of any watermark
process in the default JRE unless one is using a third-party library.

AlphaComposite, with the watermark at 5-10%.
