In Java EE 7 the HTML 5 apps actually implemented by using Java API for WebSocket, the JSON Processing API, and Servlet NIO.But in Java EE 8, Oracle plans to augment support for HTML5 apps by adding support for server-sent events, standardized binding between JSON text and Java objects, and improvements to the Java API for WebSocket and the Java API for JSON Processing. This is great news for Java EE developers.

About MVC 1.0

Leverage existing Java EE technologies
Model part should leverage CDI and Bean Validation
View part should leverage existing view technologies like JSPs and Facelets
Controller could be either JAX-RS based, invent a new technology, or defined a technology-independent way of defining

Model-View-Controller, or MVC is a common pattern in developing web applications.

Model – refers the application’s data
View – application’s data presentation
Controller – responsible for managing input, updating models and producing output

The MVC 1.0 falls into the action-based MVC and it is not a replacement for component-based frameworks such as JavaServer Faces (JSF).
