JavaME

JavaME composed of many profiles:

MIDP(Mobile Ingormation Device Profile):

The profile of choice for developing mobile phone application. It has midlet (similar to applet, servlet e.t.c) for managing application.

CLDC(Connection Limited Device Configuration):

As name implies, it is applicable for connected and limited devices. Corrently, MIDP/CLDC are used simultaneously. I would love to see CDC (no limitation) to be applicable for mobile.

Optional profile:

May of may not available to a particular handset model. In order to see whether the set supports any particular profile or not visit here. You can also get information of different features of mobile set from WURFL.
