Java EE 7 (JSR 342) news

  • Annotated POJOs, which have proven to be the cornerstone of ease-of-development paradigm since Java EE 5, continue to rule the roost and further penetrate Java EE
  • Contexts and Dependency Injection (CDI) reputation of being the ‘magic glue’ has been taken to the next level – it’s now ‘default’ in Java EE 7 and its goal is to drive cohesiveness throughout the entire EE platform
  • JMS 2.0 (JSR 343) has been completely ‘revamped‘. A ‘new version’ of the API known as the ‘Simplified API‘ is more succinct, easy-to-use and will ensure that developers have to deal with ‘significantly lesser‘ amounts of ‘boilerplate‘ code
  • JAX-RS 2.0 (JSR 339) – The RESFTful API in Java EE 7 has been further enriched, including addition of a brand new ‘client’ side API, asynchronous capabilities, Servlet Filters and Interceptors
  • Java API for WebSocket (JSR 356) provides a ‘easy-to-use’ and powerful ‘high level’ abstraction for developers to write low latency, real-time and feature rich WebSocket driven applications
  • JSON Support – The Java API for JSON Processing (JSR 353) has finally ‘standardized’ JSON processing. No more ‘third party’ libraries required for dealing with JSON.
  • Concurrency Utilities (JSR 236) API now makes it possible to fire your own threads in Java EE 7 (forbidden prior to this) in a controlled/managed fashion
  • Batch Applications for Java Platform(JSR 352) – Brand new specification in Java EE 7, providing standard way to write efficient ‘batch processing‘ applications

JSR 356, Java API for WebSocket, specifies Java API that developers can use to integrate WebSockets into their applications — both on the server side as well as on the Java client side. Tyrus is the reference implementation for JSR 356.
