    How to enable HTTP/2?

    Juergen Zimmermann Master

      I tried to enable HTTP/2 for the Undertow Subsystem, i.e. I added enable-http2="true" to the http-listener tag and to my additional  https-listener tag. However, when starting WildFly I'm getting the following log entry in server.log. Any hint is appreciated.

       

      ERROR [org.wildfly.extension.undertow] WFLYUT0071: Jetty ALPN not found. HTTP2 and SPDY are not available. Please make sure Jetty ALPN is on the boot class path.
