SEAM, JSF Image manipulation

Question

I am new to SEAM and JSF, and want to design image manipulation application using it. I am planning to use JQuery plugins at client side for image effects such as crop, rotate, resize and many more. My Concerns are,

1. I don't know about any good server-side library for this. Which would be a best for java.
2. How Clientside and Serverside manipulation will be synchronized, because if user decide to crop image at client-side, how serverside library would have information about coordinates to crop?

If you guys have any different approach than this, it would be good to learn.

Thanks, Rahul

Answer 1

Solved this by using JCrop and other JQuery plugins and using Java ImageIO at server side. JCrop works pretty much with coordinates.
