Sorry, you cannot obtain Jirachi in Diamond Version without the use of cheats. You can obtain it via Pokemon Colosseum pre-order disc though.
There are 2 ways. The first and legit way of doing it is to find the bonus disc for the American Pokemon Colosseum and get it that way by trading it to a GBA Pokemon game and transfer it to Diamond and the other way is to use and Action Replay.
