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 othermeans (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 submittersthink about how their proposed technology relates to all of the Javaplatform editions. Please provide details here for which platformeditions are being targeted by this JSR, and how this JSR hasconsidered 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?
No
2.5 What need of the Java community will be addressed by the proposed specification?
This JSR will specify the 3rd generation Mobile Information DeviceProfile, expanding upon the functionality in all areas as well asimproving interoperability across devices.
2.6 Why isn't this need met by existing specifications?
N/A 
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.)
javax.microedition.*
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?
No
2.11 Are there any internationalization or localization issues?
No
2.12 Are there any existing specifications that might be renderedobsolete, 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 thisspecification.
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 thisspecification.
The Expert Group will conduct its work in a similar fashion to theMIDP 2 Expert Group. That is, the primary means of communication willbe via email list(s) and web site(s). In addition, periodicface-to-face meetings will be held approximately every 6-8 weeks, andphone conferences as needed for special issues that need to be resolvedbetween meetings. Decisions will be made by technical consensus.
2.15 It is important to the success of the community and each JSRthat the work of the Expert Group be handled in a manner which providesthe community and the public with insight into the work the ExpertGroup is doing, and the decisions that the Expert Group has made. TheExecutive Committees would like to ensure Spec Leads understand thevalue of this transparency and ask that each JSR have an operating planin place for how their JSR will address the involvement of thecommunity and the public. Please provide your plan here, and refer tothe Spec Lead Guide for a more detailed description and a set ofexample questions you may wish to answer in your plan.
Transparency plan:a) All members of the expert group will be allowed to subscribe to andparticipate in discussions on the email list(s) as they choose. Theface-to-face meetings will be open to all active participants with alimit of one representative per company in order to keep the meetingspace to a reasonable size (i.e. approx 30-35 people). Any free seatswill be made available to Observers on some kind of simple lottery-typesystem, similar to how MIDP2 was organized.b) The specification lead will, on a quarterly basis, provide a briefJSR status to the JCP PMO, for publication to the Java community. Thiswill include the current schedule for the JSR and notes on any majorevents that have occurred in the previous quarter. 
2.16 Please describe how the RI and TCK will de delivered, i.e. aspart of a profile or platform edition, or stand-alone, or both. Includeversion 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 availablestand-alone and you are now proposing in 2.13 to only deliver RI andTCK as part of a profile or p
