问题
I have experience in java cards, but new in programming host application for Desfire, How or Where can I find command set description of Desfire? (I do not need general information like what NXP has mentioned in It's "Product short data sheet"s), I need the commands Instruction code and parameter details and responses (Like APDU or something). thanks.

I am having exact same trouble as you. The closest thing to documentation of the commands is a blog post that shows a couple of examples of what the desfire communication looks like.

But there is a library that can help you with putting desfire commands together:

Edit: It turns out that you can't get the documentation freely. You need to sign an NDA and then buy it.

Very complete command send can be found from this Host Card Emulation project. It shows how to emulate a DESFire card on Android mobile:

I found this PDF useful (third party list of commands for older model) - it can you get started with things like getting application list:

You don't need to buy it, the datasheets are free after you sign the NDA and NXP sets you up to download the secure documentation.
