How to modify EXIF metadata for JPEG images using Coldfusion?

问题

I am using Coldfusion to view images stored in the file system and I can READ the EXIF metadata of JPEGs, but I'd like to know if it is possible to modify this information and re-save the image.

I know that there are XMP and IPTC custom tags out there, I googled now and seems that javaloader.cfc + some java lib are your only sure option.

EDIT: Since I work on stock photography application I got interested and found this command line tool which could do the trick:
