One of the key Java EE 8 APIs, MVC 1.0 (JSR 371) is solidly moving forward. A key decision for the expert group to consider was whether to base the specification on Servlet or JAX-RS. MVC clearly has many semantic commonalities with both specifications such as HTTP method mapping, mime-type handling, session/request/cookie manipulation and so on. Specifications like JSF and JAX-RS are based on Servlet so it is not unnatural to base MVC on the foundational Java EE specification too. However basing MVC on the lower level Servlet specification would likely mean introducing many APIs that are potential duplicates of what is already available in the higher level JAX-RS API. On the other hand basing MVC on JAX-RS would mean significantly minimizing the possibility of API duplication. It would also mean the programming model between JAX-RS and MVC would be very similar, reducing the learning curve for both newcomers and experienced Java EE developers.

For these reasons it is not too surprising that the expert group has decided to move ahead by basing MVC on JAX-RS. MVC expert group member Ivar Grimstad shares the details including an early view on how the API may wind up looking like in a recent post. Do you have an opinion to share on this?
