The document discusses upcoming features and specifications for Java EE 7. Key points include: - Java EE 7 will include features to make the platform more suitable for cloud/PaaS deployments like multitenancy and metadata for service profiles and modularity. - Approved Java EE 7 specifications so far include JPA 2.1, JAX-RS 2.0, Servlet 3.1, EL 3.0, and JMS 2.0. Additional specifications being worked on include EJB 3.2, CDI 1.1, JSON 1.0, and web sockets. - The full Java EE 7 release is targeted for Q3 2012 and will include any specifications that can be completed

21. Where is JSF in its lifecycle?
• 2.0 was the last BIG FEATURE release
• From now on, JSF will be maintained with
smaller, more frequent releases.
• 2.1 was a small minor revision (MR)
• 2.2, for JavaEE 6, is a small JSR, done by end of
this year (2011)
• 2.3 may follow soon afterward, and will target
Java EE 7

22. What's Planned for JSF 2.2
• Let's revisit the JSR on which the JCP voted
yes

• Ease of Development
• Portlet Integration
• New Features

24. How to Get Involved
• It's complicated By Facebook Relationship Status
• Get a new job that has nothing to do with JSF
and still participate as if you were in a
relationship
• In an open relationship
• Go away from working with JSF for a while, but come back every now
and then as if you were single
• Widowed
• You don't even work in IT any more
• Separated
• You start playing around with another framework and decide you like it
better, but think maybe someday you'll come back to JSF again
• Divorced
• You leave JSF and publicly bash it, saying how great another framework
is 25

25. JSF 2.2
Conclusion
• JSF 2.2 is trying to be the fastest ever JSR
• If it's not in the issue tracker, it will not get
done, ever

28. Data Grid
Proposal
• Data grids are gaining prominence and
importance in enterprise Java, particularly as
cloud-style deployments gain popularity:
– High Availability
– Cloud-style Deployment
– Scalability
www.catmedia.us 29

29. Data Grid
Discussion
• Data Grid to JSR-107 like CDI to JSR-330 ?
• Concerns by some vendors
– Especially Terracotta (107 EG)
• What about Oracle?
– Coherence,…
• What about vmware?
• Google, Amazon,…?
www.catmedia.us 30

30. Social Networking
Initiated by Mobile, but meant to be portable
• Specify APIs to Java (ME) allowing thereby to
applications and local web services (servlets) to
interface and host 3rd party social applications (e.g.
hi5, LinkedIn, MySpace, Netlog, Ning, orkut, XING,
Yahoo! ...) similar to
– OpenSocial
– Seam Social
– Spring Social,…
www.catmedia.us 31

31. Social Networking
Main Features
• Generic Framework
• Interface for applications to define new
• Containers
• Retrieve Social Networking information
• Security ?

32. Modularity
OSGi vs. Jigsaw
• What is EE 7 going to provide?
• Will it be based on OSGi?
• How about compatibility with SE 8?
• ???
