2.1 Please describe the proposed Specification:

The J2ME Connected Device Configuration provides the basis of the Java 2 Platform, Micro Edition in devices characterized as follows:

• 512K minimum ROM available
• 256K minimum RAM available
• Connectivity to some type of network.
• Supporting a complete implementation of the Java Virtual Machine as defined in the Java Virtual Machine Specification, 2nd Edition.
• User interfaces with varying degrees of sophistication down to and including none may be supported by this configuration specification.
  TV set-top boxes, web enabled phones, and car entertainment/navigation systems are some, but not all, of the devices that may be supported by this configuration specification.

  The J2ME Connected Device Configuration will define the minimum required complement of Java Technology components and API's for connected devices. Supported APIs, application life-cycle, security model, and code installation are the primary topics to be addressed by this specification.

  For devices with less resources than this configuration requires please see JSR-000030 [J2ME Connected, Limited Device Configuration].

2.2 What is the target Java platform?

Java 2 Micro Edition

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

Provide a standard Java 2 Micro Edition configuration for connected devices.

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

Existing platforms and specifications are targeted at devices equipped with more memory, more powerful networking capabilities and more capable user interfaces, typically desktop computers.

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

See section 2.1 for expected underlying device technologies.

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

N/A

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

No.

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

None identified at this time.

2.9 Are there any internationalization or localization issues?

Requirements to be researched by the expert group developing this specification.

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

No.

There is a whitepaper describing J2ME where configurations and profiles are defined:

The J2ME whitepaper provides a framework for defining the goals and scope of the specification.
