Modifying JPEG metadata (EXIF format)

[Rupali Sarolkar]

I am using sanselan to extract metadata from JPEG file.
I am extracting Make (Camera make), Model (Camera Model), DateTime (When picture taken). I want to modify the value of DateTime field in metadata of JPEG. This metadata is in EXIF format.
Please help me !!!

Thanks in advance !!!

I'm not aware of a Java API to change EXIF data in an image. One library that can read it is this one; maybe it can be extended for writing, although I doubt it.
