JSON-P

we believe that providing solid support for standardized PaaS-based programming and multi-tenancy would delay the release of Java EE 7 until the spring of 2014

way too long

defer the remaining aspects of our agenda for PaaS enablement and multi-tenancy support to

already laid some of the infrastructure for cloud support in Java EE 7

resource definition metadata

improved security configuration

JPA schema generation

Java EE 8 Platform release for the

support for HTML 5 in the form of Web Sockets

JSON-P

simplified JMS 2.0 APIs

improved Managed Bean alignment, including

JAX-RS 2.0 client API

method-level validation

more comprehensive expression language

The discussion whether or not to use Spring vs. Java EE for new enterprise Java applications is a no-brainer

Why migrate?

since then fallen a prey to the hungry minds of Venture Capitalists and finally into the hands of a virtualization company called VMware

While the different companies and individuals behind the Spring framework have been doing some work in the JCP their voting behavior on important JSRs is peculiar to say the least

outdated ORM solution like JDBC templates

some developers completely stopped looking at new developments in the Java EE space and might have lost track of the current state of technology

size of the deployment archive

fairly standard Java EE 6 application will take up about 100 kilobytes

comparable Spring application weighs in at a whopping 30 Megabytes!

Lightweight

Firing up the latest JBoss AS 7 Application Server from scratch and deploying a full blown Java EE 6 application into the server takes somewhere between two and five seconds on a standard machine. This is in the same league as a Tomcat / Spring combo

Dependency injection

Java EE 6, the Context and Dependency Injection (CDI) specification was introduced to the Java platform, which has a very powerful contextual DI model adding extensibility of injectable enterprise services

Aspect Oriented Programming

“AOP Light” and this is exactly what Java EE Interceptors do

common pitfall when taking AOP too far is that your code might end up all asymmetric and unreadable. This is due to the fact that the aspect and its implementation are not in the same place. Determining what a piece of code will do at runtime at a glance will be really hard

Testing

With Arquillian we can get rid of mocking frameworks and test Java EE components in their natural environment
