Can JCE be used for ECC encryption?

I am trying to implement basic encryption and decryption in Java using
ECC algorithm. Is it possible using native JCE is some 3rd party API
such as Bouncy Castle a must?

Also, are there any other APIs that support ECC encryption?

some other third party has it.

I presume it has something to do with elliptical curves. BouncyCastle
has ECDSA and ECGOST.

ECC stand for Elliptic curve cryptography http://en.wikipedia.org/wiki/Elliptic_curve_cryptography
and it uses the algorithms of the elliptic curves. According to the
article is is also implemented in JCE but I have not found any good
sample. If you find any please post it ;)

Thanks for this informative link. The article suggests there may be some
patent issues. Here's an article mentioning BouncyCastle:
