There have been some mails with details about JGit from Shawn (IIRC) to this very list.

C Git patch-id takes a valid patch as input; I do not think that you want to use the Patch object.

FWIW a patch-id is nothing else than the SHA-1 of a diff where the "diff", "index", "@@" lines and all the whitespace was removed.

This is not really difficult in Java, however, it relies on a working diff implementation (and IIRC my implementation has not yet been integrated into JGit).

Ciao, Dscho
