AES Java Implementation?

Hello, Mr. Expert:
I'm looking for some completed AES crypto JAVA Implementation Class or Source code. Is there anyone know about that?
I'm trying to use 256bits key to encrypt 128 bits plain text to 128 bits Cipher text with AES Algorithm.
Please Give me some indeas?
Thank you very much!!

AFAIK bouncy castle provides an implementation of AES:

I checked All of above links already.
Sun's AES Class can't support 256 bits key.
islab's AES only can encrypt the same size of cipher text as key's size. (for example: key's size is 256bits, plain text's size is 128 bits, cipher text's size is 256 bits. actually I want cipher text's size is 128 bits as well).
in the link ....

>>What Is AES?
AES is a federal standard for private-key or symmetric cryptography. It supports combinations of key and block sizes of 128, 192, and 256.

clearly mentions it  supports combinations of key and block sizes of 128, 192, and 256........ well did you check out with the implementation.
My opinion is that points should be split between me and CodingExperts
