JUG Nürnberg – 2016-09-27

Transcript

2. Why?

4. Current Java EE Options?
5. Servlets & JSPs?
6. JSF?

9. ROCA? Resource-oriented client architecture roca-style.org
10. Goals Leverage existing Java EE technologies Integrate with CDI and Bean Validation Define a solid core to build MVC applications without necessarily supporting all the features in its first version Explore layering on top of JAX-RS for the purpose of re- using its matching and binding layers Provide built-in support for JSPs and Facelets view languages MVC Specification (Early Dra Review 2)
11. Non Goals Define a new view (template) language and processor Support standalone implementations of MVC running outside of Java EE Support REST services not based on JAX-RS Provide built-in support for view languages that are not part of Java EE MVC Specification (Early Dra Review 2)
