Actually,Im not sure how to handle (image)file that is uploaded by user to manipulate it locally using servlets? what packages can be used for this purpose?

[Ulf Dittmer]

You would use the javax.imageio.ImageIO class to read and write images from and to disk. Once you have a BufferedImage object, you can use the getRGB and setRGB methods to manipulate its pixels.
