Question

Are there any production quality JSF 2 implementations yet? If so what are they?

Answer 1

There have always been two major JSF implementations: Sun Mojarra (the reference implementation) and Apache MyFaces. Mojarra 2.0 is already been final for months (since Oct 19, 2009). The MyFaces JSF 2.0 implementation is still on its way (is still Beta). No other JSF 2.0 implementations comes to mind.

Update: as of yesterday (Apr 21, 2010), MyFaces 2.0.0 finally became final.

Answer 2

You might be asking about JSF 2 extended component suites. Primefaces released a production ready release first, I believe in February 2010. RichFaces (JBoss/Redhat) just announce a JSF 2 compatible release this week (April 2010). Icefaces is expected to release theirs in June 2010.

I've successfully used Primefaces in a JSF 2 application - worked great.
