 Wireless Application Development : Java Programming for Wireless Devices - White paper : eBiz Infosystems Inc.
The Connected Device Configuration technology (CDC) uses the CVM, a full-featured VM that is similar to a virtual machine residing on a desktop system.
When the application is executed, the device chooses the placement of a command based on the type of the command, and places similar commands based on their priorities.
The name appears in the device display so the MIDlet can be selected from the list of applications deployed in the device, the icon (if one is supplied) appears next to the name, and the class is the executable called to launch the MIDlet.

 Introduction to Wireless Technologies
Consumer and embedded devices that are not wired to the wall, but instead use a wireless technology to communicate are wireless.
Wireless devices can be so small you can carry them around in your hand, pocket, or purse, or considerably larger so they operate from one location in your home, office, or automobile.
The J2ME virtual machine and API specifications for specific device platforms are developed by soliciting input on requirements through the Java Community Process initiative to make certain the specifications meet the unique needs within a given family or category of consumer devices.

 An Overview of the File Connection Optional Package
New J2ME developers are often surprised to discover that the Connected Limited Device Configuration (CLDC) and the profiles based on it are not required to support the reading or writing of files.
The File Connection Optional Package (FCOP) is one of two optional packages defined by JSR 75 through the Java Community Process.
Devices are unlikely to support file access across a network, so in almost every case the URL will refer to the local host, and the host part of the URL is commonly omitted.

 J2ME grows up
While the applications for this range of devices differ, Java technology works to bridge those differences where it counts, allowing developers who are functional in one area to leverage their skills across the spectrum of devices and applications.
A configuration specifies a least common denominator subset of the Java language, one that fits within the resource constraints imposed by the family of devices for which it was developed.
According to its specification, the CLDC serves devices that have 512 KB or less memory, a limited power supply (typically a battery), limited or intermittent network connectivity, and a simple (possibly nonexistent) user interface.

These devices can still be connected to a network either continuously or intermittently, but they do not have the same resources as desktop computers.
First, the device, such as a PDA, connects with a UDDI Registry for dynamic lookup of a service it is interested in.
However, if you have a device that cannot handle the full JAXP and JAX-RPC stacks of software or it does not have a powerful CPU or enough memory, such as a stereo receiver, then an agent for the device should be used instead.

A J2ME configuration defines an API and a virtual machine optimized to service devices that fall into a particular range of capabilities and resources.
Aimed at the Connected, Limited Device Configuration, the KVM is only 40K of object code and needs only "a few tens of kilobytes" at runtime.
This seems like it should be obvious, since the two devices have totally different capabilities, but since portability has been so much a part of the Java message, it pays to note its limitations under the J2ME.

Configurations are meant to specify the memory and CPU requirements for target devices as well as for one or more virtual machines (such as the KVM, PersonalJava VM, Classic VM, and so on) and for core J2ME APIs that may be used to implement the base J2ME functionality on these devices.
Configurations and profiles are an attempt to engineer reasonable sets of compromises for related families of devices and end user applications.
Even though a device's ROM is being used, it is still possible to use many of POSE's debugging features, including its interestingly named Gremlins, to generate random input.

A configuration is "generic" in the sense that it is not targeted at any particular type of device.
In essence, the configuration defines the core language and Java VM features that can be supported on a range of devices, along with a very small set of essential class libraries.
For one, screen updates on many small devices are very slow, and as a result the animation would not be very smooth, or it might overtax the resources of the device.

 Web Services APIs for J2ME, Part 1: Remote service invocation API
These are targeted at both the Connected Device Configuration (CDC) and the Connected Limited Device Configuration (CLDC 1.0 and CLDC 1.1)-based profiles.
Note that JSR 172 does not mandate the use of XML encoding on the device itself, allowing implementations (as long as they're transparent to both consumer and producer) to use more efficient encoding approaches, such as the use of binary protocols between the device and the wireless gateway.
This is to help reduce network traffic by allowing implementations to use more efficient data encoding, such as a binary protocol between the device and the wireless gateway, as long as such encoding is transparent to both the Web service consumer and the producer.
