9 Reasons why Java EE 6 will save $$

• Prototyping (multiple IDEs)• Development (~30MB, incremental deployment, ...)• Production (Variety, Start small/then scale)• Support (Pick the best one)• Training (“Only” Java EE 6 APIs)• Portability (Backwards compatibility)• Adoption (Growing)• Freedom of choice (Multiple vendors)• Plan B (Similar component models)

From real Java EE 6 users ...

Developers can concentrateon business logic, Java EE 6 is providing a standard for

the infrastructure.

Jigsaw puzzle, Modular, standard,

less xml, easy, easy, have I said easy?

Higher integrated specs,simple and annotation driven,

single-classloader WARs,next level of industry

standard

Standards compliance, vendor independence, milliseconds

and kilobyte deployment

In selecting an application server our main goal was to avoid the framework explosion that

happens when you use a "custom" Enterprise stack like Tomcat + Spring + Hibernate + Myfaces +... Java EE 6 had 80% of what we

needed out of the box: strong persistence support ( JPA ), inversion of control ( CDI ), and

a lightweight component model ( EJB 3.1 )

Avoid “framework explosion”

The Age of Frameworks is Over

Frameworks like Spring are really just a bridge between the mistakes of the J2EE past and the success of the Java EE 6 future. Frameworks are out, and extensions to the Java EE 6 platform are in. Now is the time to start looking past Spring, and looking forward to Seam and Weld and CDI technologies.

Java EE has far surpassed Spring, which always felt as a patched together thing instead of a coherent whole. Spring seems to be resting too much on their laurels, and keep thinking they invented DI and therefor will be the leading platform forever. Now it's Spring who's limping behind.

Misc quotes/points ...

• Rod Johnson - taken a look at GlassFish and given it the thumbs up

• Jurgen Holler - A Java EE 6 server like GlassFish 3 is a fine runtime environment for Spring 3

• Adam Bien - With Spring, you need support from two companies

• WAR = 90% framework + 10% app ?• Spring becoming a technical debt ?

First they ignore you, Then they laugh at you, Then they fight you, Then you win.

What's cool about Java EE 6 ?

• Java EE: Cooperate on standards, compete on implementations

• Java EE 6 = Simplicity + Flexibility + Extensibility• Growth of Adoption (70% using EE 5/6)• No vendor lock-in• YOU help us define it!
