To set up and run a J2ME Midlets, one requires the minimum Java technology that an application developer can expect and that too on a variety of implementing devices, this makes J2ME much more useful than any contemporary technology.
What are MIDlets ?
These are applets for mobile phones. Just like any other applet, they also run in a protected sandbox - the KVM - only difference is that they are extremely limited. On majority of Java-capable phones, you will find MIDP 1.0 which is fairly restrictive. For an example - One is not allowed to process floating point numbers yet in KVM. This means that MIDlets written for MIDP 1.0 can not access anything which is outside the sandbox without having proprietary APIs from the manufacturers of the device.
MIDlets are distributed and packaged as MIDlets suites, which in turn may contain one or more MIDlets. A MIDlets suites contains two files : Java Application descriptor (a .jad file) and Java Archive file (a .jar file)
The Java 2 Platform micro edition provides great tools which are very useful for the development and broadly used by Java Developers. It is of great importance to understand the building blocks of J2ME Platform and to go through it's functioning with the help of sample applications.
On eZdia you may find different J2ME Tutorial which will guide you through the construction of a elementary MIDP application. Experts in J2ME will illustrate how you can use the Mobility module for the creation, debugging and running of an application on the device emulators embedded in various IDE. END AKISMET -->
