You can not get a mew in Pokemon Diamond without trading or cheating (HIGHLY NOT RECCOMENDED.) but there is a way to get a mew in the following games: Pokemon Blue, Pokemon Red, or Pokemon Yellow. look up "Mew Glitch" in Google search and find out how. hope this helped!
You can't get a Shadow Mew in Pokémon Diamond because there's no such thing as a Shadow Mew in Pokémon Diamond.
You have to upload it from FireRed, LeafGreen, Ruby, Sapphire, or Emerald.

you don't, you migrate it from Pokemon ranger, have fun on you're game, I can catch every Pokemon exept mew.
Its impossible.Although you may see your friends throw out Mew from time to time, and Mew up for grabes on the global trading system, it is impossible to catch Mew on Pokemon Diamond. This doesn't mean you can't have her on your game.If you catch a mew on Pokemon Fire Red or Leaf Green, you can migrate it to your game if you have completed the game.
