Jetty 9 connector for Restlet 2.2+

This Restlet extension allows you to use Jetty 9.3 as both a server and client connector, for both HTTP and HTTPS. HTTP/2 is supported for the server connector.

Note that Jetty 9.3 requires a JVM of at least version 8.

See also this issue and the Restlet forum.

HTTP/2 Server

1. Dependencies: Jetty HTTP/2 server and HPACK, as well as an ALPN boot solution.

2. The ALPN boot jar needs to be added to the JVM's boot classpath. E.g.:

   java -Xbootclasspath/p:<path_to_alpn_boot_jar> ...

3. You need to configure your Server for HTTP/2. As of Restlet 2.3, the Protocol class does not have HTTP version 2 constants, but they are available in this driver in the [Http2 utility class] (http://threecrickets.com/api/java/restlet-jetty9/index.html?org/restlet/ext/jetty9/Http2.html). Here's some pseudo-code to create a server that supports both HTTP/2 and legacy HTTP/1.1:

   import org.restlet.Server; import org.restlet.ext.jetty9.Http2; Server server = new Server(Http2.HTTPS_PROTOCOL, 443) server.getProtocols().add(Protocol.HTTPS) component.getServers().add(server)

HTTP/2 Cleartext Server

Supported for servers only via the Http2.HTTP_PROTOCOL constant.

Note that as Jetty 9.3, it does not support HTTP/2 cleartext for clients. (Generally speaking, it's unclear at this point if the industry will embrace this variant, and it's difficult to find tools to test it.)
