Hi all,

Searching Google for these things can get you some very good information. For example:
http://en.wikipedia.org/wiki/Mobile_...Device_Profile
http://en.wikipedia.org/wiki/Connect..._Configuration

Basically CLDC consists of low-level interfaces on which MIDP is built, and MIDP contains the APIs programmers use to create applications.

Also, the Forum Nokia Library describes these things:

Configuration
defines the minimum Java
technology that an application developer can
expect on a broad range of implementing
devices.
J2ME Configurations
• J2ME Connected, Limited Device
Configuration (CLDC)
– Specifies Java environment for mobile phone,
pager and PDA class devices
– CLDC devices are usually wireless
• J2ME Connected Device Configuration (CDC)
– Specifies Java environment for digital television
settop boxes, high end wireless devices and
automotive telematics systems.
– CDC devices may be wired (DTV cable, etc.)

PROFILE
Java technology which supplements a
configuration to provide capabilities for a
specific vertical market or device type
•Defined through Java Community Process
initiative
•Subject to compatibility tests
J2ME Profiles - MIDP
• J2ME Mobile Information Device Profile (MIDP)
– Application runtime environment for wireless
devices based upon CLDC
• J2ME Foundation Profile
– Base profile for non-GUI networked devices based
upon CDC
• J2ME Personal Basis, Personal, and RMI Profiles
– Basic graphics and RMI support for CDC &
Foundation Profile based devices
