Java EE 6 provides several improvements that make application development simpler, more flexible, and extensible. Key improvements include support for annotations and POJOs, a lightweight web profile, and embracement of open source frameworks. Java EE 6 also sees growing adoption rates and ensures freedom of choice between implementations from different vendors.

16. 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)

17. From real Java EE 6 users ...
Developers can concentrate Jigsaw puzzle,
on business logic, Java EE 6 Modular, standard,
is providing a standard for less xml, easy, easy,
the infrastructure. have I said easy?
Standards compliance, vendor
Higher integrated specs,
independence, milliseconds
simple and annotation driven,
and kilobyte deployment
single-classloader WARs,
next level of industry
standard

18. Avoid “framework explosion”
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 )

19. 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.

20. 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 ?

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

22. 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!
