  Enterprise Java Community: Working with J2ME
J2ME is not without its warts, including a large number of specifications and technologies.
Before examining implementation details of a networked J2ME client, it is worth exploring the basics of the J2ME platform and the applications written for it, known as midlets.
J2ME emulators mock up the J2ME runtime environment on a desktop PC, allowing development to occur on a device that has more memory, a faster network connection, and a keyboard.

 Dr. Dobb's | Getting Personal with J2ME's PIM API | March 1, 2006
Until recently, all I could do was explain that this missing capability was for the sake of security, which is not an idle concern when your mobile phone carries all sorts of personal data on it.
Because to-dos often have a time dependency such as a deadline date, the to-do list is often considered an extension of the calendar, even though it is implemented as a separate object with its own fields and methods in the PIM API.
A J2ME device has only one configuration layered over the device's hardware and native OS, while multiple profiles can be layered atop of the configuration to add other capabilities.

 ONJava.com -- What's J2ME?
Java 2 Micro Edition (J2ME) is Sun's version of Java aimed at machines with limited hardware resources such as PDAs, cell phones, and other consumer electronic and embedded devices.
J2ME is aimed at machines with as little as 128KB of RAM and with processors a lot less powerful than those used on typical desktop and server machines.
The first thing to realize is that just because J2ME is Java, that doesn't mean you can take your existing Java applications, re-compile them, and have them run on new devices.

 Getting to Know the J2ME Emulator > J2ME Emulator Essentials
A J2ME emulator is an important tool that ships with both the standard J2ME Wireless Toolkit and with other similar toolkits that are made available by device vendors such as Motorola.
The J2ME emulator is the tool that enables you to run MIDlets on a desktop PC and simulate how the MIDlet will run on a physical device.
The last limitation of the J2ME emulator is less critical than the first two, and has to do with the application manager that is used on mobile devices to manage MIDlets.

 ACM Queue - Java in a Teacup: Obsessed with cellphone games? You can create your own with J2ME.
The J2ME world is divided broadly into two classes: one servicing devices with less than 512 KB of memory (things you hold in your hand), and the other servicing those with larger memory footprints (things you plug into a wall).
These classes of devices are the basis of the two J2ME configurations: CDC (connected device configuration) and CLDC (connected limited device configuration).
J2ME devices may implement one or more of the optional packages as well, such as Bluetooth support, RMI (remote method invocation), and the mobile media API.

Java ME (J2ME) on handsets like cell phones is supported by ALL the major carriers (including Verizon Wireless, which had previously been a BREW-only supporter), unlike its competitors like BREW and Microsoft technologies.
Java ME (J2ME) on handsets is strongly pushed by ALL the major phone vendors (Nokia, Motorola, Sony-Ericsson, etc), unlike partial competitors like BREW (which is not supported by the major phone vendors because they have their own competing OS called Symbian) or the competing Microsoft technology (which is a fringe player at best).
More than 97% of all handheld software sold in 2001 was for the Palm OS, and Palm OS is gaining dominance in the enterprise as well, with Palm OS licensees accounting for more than half of all handhelds sold to enterprises worldwide, compared to 32 percent for Pocket PC licensees.
