Meloetta can be caught in both versions of Pokémon Black, but not Pokémon White.
However you can only get it through an event, see the related link below.
there will not be a Meloetta event for Pokemon White because normally Nintendo has events when a new Pokemon game comes out. the next Pokemon game is Pokemon Black and White 2 in October in 2012. the only way to get Meloetta in Pokemon white is use action replay or have a glitch in your game.
A trade is required from white or white 2 where it can be caught
Unfortuntately bar cheating or getting very lucky and being able to trade with someone who has one there is no way to get one.

You can catch legendaries in any Pokemon game! (At least after you know where they're hiding!)
