Chapter 1. Java 2, Micro Edition: Configurations, Profiles, and Virtual Machines

This chapter discusses the J2ME standard and how it relates to PDAs.

J2ME is defined in terms of configurations and profiles. A configuration is a building block for basic functionality, whereas a profile builds on top of an existing configuration. Thus, a profile provides richer functionality that exploits the capabilities of the target device. Additionally, optional packages can be defined on top of profiles and configurations.
