Java EE 8 augments support for HTML5 applications by adding support for server-sent events, standardized binding between JSON text and Java objects, HTTP/2 support and improvements to the Java API for WebSocket and the Java API for JSON Processing. Java EE 8 aligns with Java SE 8 so that developers will be able to take advantage of new features such as repeating annotations, lambda expressions, the Date/Time API, type annotations, Completable Futures etc.
