Section 2: Request

2.1 Please describe the proposed Specification:

This JSR will build upon the success of MIDP2 by enhancing the Profile with the following additions/changes:

    * Enable and specify proper behavior for MIDlets on each of CLDC, CDC, and OSGi, for example:
      o Enable multiple concurrent MIDlets in one VM
      o Specify proper firewalling, runtime behaviors, and lifecycle management issues for MIDlets
      o Enable background MIDlets (e.g. UI-less)
      o Enable ?auto-launched? MIDlets (e.g. started at platform boot time)
      o Enable inter-MIDlet communications

    * Enable shared libraries for MIDlets
    * Tighten spec in all areas to improve cross-device interoperability
    * Increase functionality in all areas. E.g.
      o Improve UI expressability and extensibility
      o Better support for devices with larger displays
      o Enable MIDlets to draw to secondary display(s)
      o Enable richer and higher performance games
      o Secure RMS stores
      o Removable/remote RMS stores
      o IPv6
      o Multiple network interfaces per device

    * Specify standard ways for doing MIDlet provisioning through other means (e.g. OMA (SyncML) DM/DS, Bluetooth, removable media, MMS, JSR-232, etc.)
    * Extensive device capabilities query
    * Localization & Internationalization (if appropriate, integrating/augmenting JSR-238 as needed)

A key design goal of MIDP3 will be backward compatibility with MIDP2 content.

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

MIDP on Mobile Handsets

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.

The target platform is the MID Profile in J2ME.

2.4 Should this JSR be voted on by both Executive Committees?


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

This JSR will specify the 3rd generation Mobile Information Device Profile, expanding upon the functionality in all areas as well as improving interoperability across devices.

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


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

CLDC, CDC, OSGi, and MIDP 2.0

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


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


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


2.11 Are there any internationalization or localization issues?


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

Yes. JSR-118 MIDP 2.0

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

The targeted schedule for the JSR is as follows:
- Expert Group formation: March 2005
- Early Draft Review: September 2005
- Public Review: January 2006
- Proposed Final Draft: March 2006
- Final Approval Ballot: May 2006

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

The Expert Group will conduct its work in a similar fashion to the MIDP 2 Expert Group. That is, the primary means of communication will be via email list(s) and web site(s). In addition, periodic face-to-face meetings will be held approximately every 6-8 weeks, and phone conferences as needed for special issues that need to be resolved between meetings. Decisions will be made by technical consensus.

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.

Transparency plan:
a) All members of the expert group will be allowed to subscribe to and participate in discussions on the email list(s) as they choose. The face-to-face meetings will be open to all active participants with a limit of one representative per company in order to keep the meeting space to a reasonable size (i.e. approx 30-35 people). Any free seats will be made available to Observers on some kind of simple lottery-type system, similar to how MIDP2 was organized.
b) The specification lead will, on a quarterly basis, provide a brief JSR status to the JCP PMO, for publication to the Java community. This will include the current schedule for the JSR and notes on any major events that have occurred in the previous quarter.

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.

An independent RI and TCK will be produced as a part of this JSR with each being licensed separately.

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).


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

These terms only represent the initial commercial terms to be used and remain subject to the execution of final legal agreements covering the subject matter hereof to be determined by Motorola at its sole discretion.

We will license to all interested parties.

Independent implementations will be allowed - TCK and RI will be licensed separately.

For TCK we plan to charge a single one-time fee for access and an annual maintenance fee for a term of four years. The actual size of the license fees will be based on the associated development cost, with a target of cost recovery. Since MIDP is much larger and more complex than most other JSRs, we anticipate the fees of $100,000 USD for one-time fee and $50,000 for annual maintenance fee.

TCK will include both binary environment and source code of the test suite.

Maintenance fee covers limited basic support, first level TCK appeals process, bug fixes when available and updates, which are due to changes in the specification. Major new releases may be subject to additional single one time fee.

For RI in source code form we will charge a per unit license fee. Maintenance releases will cover bug fixes, updates and new releases necessary due to spec changes, and when made generally available by specification lead.

Section 3: Contributions

3.1 Please list any existing documents, specifications, or implementations that describe the technology. Please include links to the documents if they are publicly available.

JSR-118 MIDP 2.0

3.2 Explanation of how these items might be used as a starting point for the work.

This specification will serve as the basis for beginning the work, which will be extended, enhanced, and clarified. Note that backward compatibility with specified MIDP 2.0 behaviors will be of paramount importance wherever possible.
