But JDK 1.7 provides native

The Java SE 7 release adds the following features:

Elliptic Curve Cryptography (ECC) A new native provider has been added to the Java SE 7 release that provides several ECC-based algorithms (ECDSA/ECDH). See Sun PKCS#11 Provider's Supported Algorithms in Java PKCS#11 Reference Guide for more information.

Even in Java 6, I couldn't get ECC to work through standard JCA APIs alone. I had to reference Sun's sun.security.ec.NamedCurve class to get the EC parameters initialized correctly, and I had to install the BouncyCastle as a provider as well.

From my experience, I don't think one can implement ECC code that is portable across security providers. While small, you'll have direct dependencies on BouncyCastle APIs.

You should have a look at Bouncy Castle - Using Elliptic Curves, there are some examples how to use it.
