Section 2: Request

2.1 Please describe the proposed Specification:

This JSR requests the creation of the next version of the Portlet Specification. An update is necessary to address progress in Java EE Java technology that has taken place since JSR286 Portlet Specification 2.0 became final in 2008 and also to address new technology themes that have since come into focus. In particular we propose the following topics for the next version of the Portlet Specification:

* Align with JEE 7 Specifications
* Specify how resources can be shared between portlets
* Improve support for mobile devices
* Improve client-side support
* Optimize support for Java Server Faces
* Add Web Socket Support
* Align portlets with the with OpenSocial standard
* Extend the portlet eventing capability
* Alignment with a future version of the WSRP specification
* Additional extensions, corrections and clarifications to JSR 286

2.2 What is the target Java platform? (i.e., desktop, server, personal, embedded, card, etc.)

The Portlet Specification is an extension to the Java EE platform.

2.3 The Executive Committees would like to ensure JSR submitters think about how their proposed technology relates to all of the Java platform editions. Please provide details here for which platform editions are being targeted by this JSR, and how this JSR has considered the relationship with the other platform editions.

As the Portlet Specification is an extension to the JEE platform, it is only relevant to that platform.

2.4 What need of the Java community will be addressed by the proposed specification?

Version 2.0 of the Portlet Specification was aligned with J2EE 1.4 and the underlying Java EE technology has changed considerably since that time. Important functionality such as JSF has been extended and new technology such as CDI has been added. It is important to the Java community that Portlet Specification be updated to align with the current Java EE version.

Also, client-side processing and mobile device support requirements have become more important over the last several years, leading to a need for improved and extended support for these technologies. The proposed next version of the Portlet Specification will provide portlet developers in the Java community with state-of-the-art tools to address these needs.

2.5 Why isn't this need met by existing specifications?

The new version of the Portlet Specification will address technology requirements that became apparent after completion of the current version.

2.6 Please give a short description of the underlying technology or technologies:

Version 3.0 of the Portlet Specification will be based on the version 2.0 that was defined in the JSR 286. Version 3.0 will be binary compatible with Version 2.0.

2.7 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)

javax.portlet.

2.8 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?

No.

2.9 Are there any security issues that cannot be addressed by the current security model?

No.

2.10 Are there any internationalization or localization issues?

No.

2.11 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?

This specification would replace and extend the JSR 286 Portlet Specification 2.0 in a compatible manner. At this point, it is not anticipated that any programming interfaces defined by the current version will need to be deprecated.

Depending on decisions taken by the workgroup, JSR 329 ?Portlet 2.0 Bridge for JavaServerTM Faces 1.2 Specification? will potentially need to be revised.

2.12 Please describe the anticipated schedule for the development of this specification.

The schedule will be determined by the expert group. Initial target is to have a working EG by May 2013, a early draft beginning of 2014, a public draft by mid 2014 and a final version by end of 2014.

2.13 Please describe the anticipated working model for the Expert Group working on developing this specification.

We anticipate a mixture of mailing list and occasional face to face or teleconference meetings.

2.14 Provide detailed answers to the transparency checklist, making sure to include URLs as appropriate:

Is the schedule for the JSR publicly available, current, and updated regularly?
The schedule will be available on the project page for the JSR: http://java.net/projects/portletspec3/pages/Home

Can the public read and/or write to a wiki for the JSR?
We will use a public mailing list for comments. See: http://java.net/projects/portletspec3/lists

Is there a publicly accessible discussion board for the JSR that you read and respond to regularly?
We'll track such discussions and respond to them on the public comment mailing list. See: http://java.net/projects/portletspec3/lists

Have you spoken at conferences and events about the JSR recently?
No, but I have spoken at conferences about its predecessor JSR 286 Portlet Specification 2.0.

Are you using open-source processes for the development of the RI and/or the TCK?
Yes, the RI & TCK will be developed using open-source processes.

What are the Terms of Use required to use the collaboration tools you have prepared to use with the Expert Group, so that prospective EG members can judge whether they are compatible with the JSPA?
See the java.net Terms of Use: http://www.java.net/javanet-web-site-terms-use

Does the Community tab for my JSR have links to and information about all public communication mechanisms and sites for the development of my JSR?
Yes, there will be a link to the project page for the JSR. The appropriate link would be: http://java.net/projects/portletspec3/pages/Home

2.15 Please describe how the RI and TCK will de delivered, i.e. as part of a profile or platform edition, or stand-alone, or both. Include version information for the profile or platform in your answer.

The RI will be implemented inside the open source project Pluto at Apache.

RI and TCK will be stand-alone versions based on JEE 7.

2.16 Please state the rationale if previous versions are available stand-alone and you are now proposing in 2.13 to only deliver RI and TCK as part of a profile or platform edition (See sections 1.1.5 and 1.1.6 of the JCP 2 document).

Not applicable.

2.17 Please provide a description of the business terms for the Specification, RI and TCK that will apply when this JSR is final.
