Correct. This is primarily because ALPN support is not there in JSSE yet and wont be until Java 9. That said, one of the reasons for the huge amount of connector refactoring that I did before starting on HTTP/2 was so that the connector implementation specific code was kept to a minimum (so far just ALPN). HTTP/2 will work just fine with NIO and NIO2 just as soon as JSSE support ALPN and we plumb it in. h2c support (HTTP/2 over a cleartext channel via HTTP upgrade rather than TLS) is also on the TODO list. It shouldn't be much work to add (less than a day) and it wil be available for all connectors. > >> Also, I think Tomcat supports websockets which has the important >> capabilities that http/2 has and has been available longer. > > Tomcat supports Websocket since Tomcat 7, as long as you are running > on Java 7 or higher. > >> Depending upon your strategy you might want to go with that or wait >> a couple of years for http/2.

Tomcat has no choice (application developers do). Servlet 4.0 will require HTTP/2 so Tomcat has to support it. > Correct.

I think the httpd thinking around WebSockets and the Java world thinking about WebSockets aren't quite lined up.
