This is the first blog post in a series where I will cover how to build web applications in Java using Java EE 7. Java EE 7 is the latest release of the Java Enterprise Platform, with a focus on HTML 5 and developer productivity.
Java EE 7 introduced five new specifications covering WebSockets (JSR-356), JSON Processing (JSR-353), Batch Applications (JSR-352), Concurrency Utilities (JSR-236), and Caching (JSR-107). Apart from these new specifications, three existing specifications (JAX-RS 2.0, JMS 2.0, and EL 3.0) have major updates and a few other specifications have minor updates. We will cover most of these specifications in detail in this blog post series.
