How I'm gonna put a path to alpn boot jar if I don't have any? Here is the link: https://www.eclipse.org/jetty/documentation/current/alpn-chapter.html <https://www.eclipse.org/jetty/documentation/current/alpn-chapter.html> If you could help me I would appreciate. 2015-11-10 7:34 GMT-03:00 Tomaž Cerar <tomaz.cerar(a)gmail.com <mailto:tomaz.cerar@gmail.com>>: First you will need client api that knows how to handle HTTP2. java's URL/URI currently don't support http2 at all. There is JEP http://openjdk.java.net/jeps/110 <http://openjdk.java.net/jeps/110> to add support for it in JDK 9. AFAK at the moment only https://github.com/square/okhttp <https://github.com/square/okhttp> client properly supports http2. But there is lots of development going on around this topic, best to look the internet for solution that suits you best. -- tomaz On Mon, Nov 9, 2015 at 9:12 PM, jorge lima <jorge.ayala2012(a)gmail.com <mailto:jorge.ayala2012@gmail.com>> wrote: Hi, thanks for the answer. But what I really need to know is to discover if some website uses HTTP/2 or not, like how we use in URLConnection with Java: URL url = new URL("https://developer.jboss.org/ <https://developer.jboss.org/>"); Map<String, List<String>> map = new HashMap<>(); URL obj = new URL(url.toString()); URLConnection conn = obj.openConnection(); map = conn.getHeaderFields(); ...
