2.1 Please describe the proposed Specification:This JSR is to develop Java EE 6, a release of the Java Platform, Enterprise Edition targeted to ship in 2008. In the past 8 years, the Java EE platform has grown and matured, and is now able to cover a wide range of enterprise and web application development needs. In addition, the Java EE platform has fostered a vibrant community and marketplace for additional technologies, frameworks, and applications that work with the platform. Some of these provide facilities that are missing from the platform. Others provide alternatives to platform facilities. A major theme for this release is to embrace and support those technologies as part of the overall Java EE landscape, while also continuing to simplify the platform to better target a wider range of developers. To that end we propose two goals for this release - extensibility and profiles. ExtensibilityIt would not be appropriate for the Java EE platform to grow without bound to include all the interesting and useful technologies desired by web and enterprise application developers. Instead, we believe it is desirable to enable more of these technologies to cleanly layer on or plug in to Java EE application servers. By adding more extensibility points and more service provider interfaces, these other technologies can plug in to platform implementations cleanly and efficiently, and be just as easy to use for developers as the facilities that are built into the platform. ProfilesThe reach of the Java EE platform has become so broad that it has lost some of its original focus. To refocus the Java EE platform on particular classes of developers and applications, we propose the introduction of Java EE platform Profiles. Profiles will reference the Java EE platform, as defined by the JCP process, and may include a subset of Java EE platform technologies, additional JCP technologies not part of the base Java EE platform, or both. In addition to defining the base Java EE platform, this specification will define the rules for referencing Java EE platform technologies in Java EE Profiles. This expert group will also define the first version of a Java EE Web Profile - a subset of the Java EE platform targeted at web application development. This profile will provide a more gentle introduction to the Java EE platform, providing only those technologies needed by most web application developers, without the enterprise technologies that sometimes confuse such developers. PruningThe use of profiles is one tool to address the ever increasing size of the Java EE platform. It's also the case that some technologies included in the Java EE platform are no longer as relevant as they were when they were introduced to the platform. There needs to be a way to "prune" these technologies from the platform in a careful and orderly way that minimizes the impact to developers using these technologies while allowing the platform to grow even stronger. We propose to use the process defined by the Java SE expert group. In short, that process defines two steps:
As defined by that process, this expert group will consider technologies that should be marked for possible removal in a future Java EE platform specification. Possibilities include:
SOA SupportThe Java EE platform is already widely used for SOA applications. As more and more enterprises realize the benefits of a SOA architecture, requirements on the platform have increased, both in terms of functionality and interoperability. J2EE 1.4 delivered basic web services support, including support for the WS-I Basic Profile, for the Java platform. Java EE 5 delivered additional web services support. Web service standards continue to evolve and it is critical that the Java platform support the latest web service standards. Java EE 6 will need to consider additional web services support. While basic web services support is now part of the Java SE 6 platform, this specification will require newer versions of these technologies that provide additional web services support. The Service Component Architecture is defining facilities that could be used by composite applications in a SOA environment. This expert group will consider whether any of the SCA-defined facilities are appropriate for inclusion in this release of the Java EE platform. Other AdditionsJava EE 5 represented a major step forward in making it easier to develop applications for the Java EE platform. Additional improvements in this area are expected in this release. This JSR will not itself define any new APIs, rather it will enumerate APIs defined in other JSRs or through the JCP maintenance process. Java EE 6 is the Enterprise Edition of version 6 of the Java platform, and thus will be built on Java SE 6. We propose to include the following new JSRs in Java EE 6:
In addition, we expect to update the following existing technologies for Java EE 6:
The exact set of technologies to be included will be determined by the expert group and will be based on partner and customer requirements. DeferredConsideration of the following JSRs, while important to the Java EE community, will be deferred to future Java EE Profiles:
To better support the extensibility goals of the platform it would be useful to have a more general concept of modules. Such work is underway in JSR-277 - Java Module System, which is targeted for Java SE 7. We anticipate that Java EE 7 will build on that technology and thus we will defer specification of any potentially conflicting technology to a future release. 2.2 What is the target Java platform? (i.e., desktop, server, personal, embedded, card, etc.)This specification defines a release of 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.This JSR updates a platform edition and defines how profiles may be created based on that platform edition. Should this JSR be voted on by both Executive Committees?No. SE/EE EC Only. 2.5 What need of the Java community will be addressed by the proposed specification?Java EE 6 will extend the capabilities of the Java EE platform to include many new technologies under development in the JCP. 2.6 Why isn't this need met by existing specifications?While existing (in progress) specifications provide the base capabilities, no other specification can unite these components into a coherent Java platform. 2.7 Please give a short description of the underlying technology or technologies:A detailed description of Java EE functionality can be found in the Java EE Specification, http://java.sun.com/javaee/download.html#platformspec. 2.8 Is there a proposed package name for the API Specification? (i.e., javapi.something, org.something, etc.)The Java EE platform itself does not require a package name. All of its requirements are reflected in the packages of its constituent Java APIs. 2.9 Does the proposed specification have any dependencies on specific operating systems, CPUs, or I/O devices that you know of?No. 2.10 Are there any security issues that cannot be addressed by the current security model?Java EE 6 addresses mechanisms and policies required for secure usage of its constituent component models and access APIs. These mechanisms must be compatible with the security facilities of Java SE 6. In addition, Java EE 6 will define additional Service Provider Interfaces, including those that allow security technology vendors to integrate with Java EE application servers. 2.11 Are there any internationalization or localization issues?Java EE uses the I18N support in Java SE and defined in constituent technologies. 2.12 Are there any existing specifications that might be rendered obsolete, deprecated, or in need of revision as a result of this work?Other than the Java EE specification itself and the new versions of its constituent component models and access APIs, Java EE 6 should not require other existing specifications to be revised. Java EE 6 may recommend deprecation of some items as described above under "Pruning". 2.13 Please describe the anticipated schedule for the development of this specification.We hope to deliver the final specification, reference implementation, and TCK in the fall of 2008. This implies that the specification must reach Proposed Final Draft by early 2008. A rough schedule would be:
2.14 Please describe the anticipated working model for the Expert Group working on developing this specification.The primary means of communication will be email, with conference calls and face-to-face meetings scheduled as needed. 2.15 It is important to the success of the community and each JSR that the work of the Expert Group be handled in a manner which provides the community and the public with insight into the work the Expert Group is doing, and the decisions that the Expert Group has made. The Executive Committees would like to ensure Spec Leads understand the value of this transparency and ask that each JSR have an operating plan in place for how their JSR will address the involvement of the community and the public. Please provide your plan here, and refer to the Spec Lead Guide for a more detailed description and a set of example questions you may wish to answer in your plan.The code for the Reference Implementation for all Sun-led components will be developed as part of the open source GlassFish Project. In addition, new features of the JCP web site will be used to keep the community up to date on the progress of the specification. 2.16 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 and TCK for Java EE 6 will be delivered in the same way they were delivered for Java EE 5. The RI and TCK for the Java EE 6 Web Profile will be delivered in a similar manner. 2.17 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).N/A 2.18 Please provide a description of the business terms for the Specification, RI and TCK that will apply when this JSR is final.Java Platform, Enterprise EditionPursuant to Section 2.2.1 of the Java Community Process version 2.6, the following is a summary of Sun's anticipated principal license terms and conditions for Java Platform, Enterprise Edition 6.
