Schedule
Not in Narnia Years…
First seven JSRs already approved
Remaining ones (to be) filed soon
EJB 3.2 and CDI 1.1 proposed
JSON 1.0 draft posted publicly
Final release by Q3 2012
Time-Boxed: anything not ready will be deferred to Java EE 8

www.catmedia.us

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

What's Planned for JSF 2.2
Let's revisit the JSR on which the JCP voted yeshttp://jcp.org/en/jsr/proposalDetails?id=344

Howto Get InvolvedBy Facebook Relationship Status
It's complicated
Get a new job that has nothing to do with JSFand still participate as if you were in arelationship
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

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, everhttp://jsf-spec.java.net/issues/

JPA 2.1
Let's revisit the JSR on which the JCP votedhttp://jcp.org/en/jsr/proposalDetails?id=338
Bulk Update/Delete
Support for Stored Procedures
Named Queries
Improved SQL Result Set Mapping

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
29
www.catmedia.us

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,…?
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,…
31
www.catmedia.us

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?
