title: How to add ALPN to Java 7
body: <p>Is possible to add ALPN to the boot class path in a Java 7 application? If yes, how can we do it?</p>
  
  <p>There're many samples on Internet telling how to do it via Java 8 and Undertow, Tomcat, Jetty, etc..</p>
  
  <p>Do I need to add a security library into my VM? It seems Java 8 already includes them.</p>
