There are _tons_ of image manipulating programs out there.  Nearly all 
of them support some kind of cropping.

The problem I found was that none provided an efficient workflow to deal 
with a large number of images where each image needed to be cropped 
differently (or at least, a large number of the set did).

Irfanview and ImageMagick are both well-known utilities, and they offer 
decent batch processing features.  But neither allow per-image 
customization of the batch processing.

A few year ago I got tired of cropping thousands of images in Photoshop 
one at a time (too much clicking), so I wrote a very simple utility to 
do it for me.  The main feature of the tool is that it will crop, 
optionally scaling the image, with a minimum number of clicks.

If you're curious, you can check it out here:

If you know in advance that every image will need the same cropping 
applied to it, then I think the batch features in the other programs are 
more likely to suit your needs.

Note that since my utility was written using .NET (Windows) and Cocoa 
(Mac), this is technically entirely off-topic here.  If you're looking 
specifically for a Java implementation, I don't have an answer for that.  :)
