This article, the first in a series on J2ME programming, explains what J2ME is. |

At the heart of Java 2 Micro Edition (J2ME) are three core concepts: configurations, profiles, and optional packages. You can't write a J2ME application without understanding these concepts, because they determine the features of Java that you can use, which application programming interfaces (APIs) are available, and how your applications are packaged... |

At the core of Java 2 Micro Edition (J2ME) are the configurations, the specifications that define the minimal feature set of a complete Java runtime environment. J2ME currently defines two configurations. In this article we look at the first of these, the Connected Limited Device Configuration, or CLDC for short... |

The second configuration at the core of Java 2 Micro Edition (J2ME) is the Connected Device Configuration, or CDC for short. The CDC is a superset of the Connected Limited Device Configuration (CLDC). It provides a much more conventional Java 2 runtime environment... |

Although configurations are at the heart of Java 2 Micro Edition (J2ME), it's the profiles that are of real interest. Profiles define the application programming interfaces (APIs) that are required to write useful applications for a particular group or family of J2ME devices. The Mobile Information Device Profile (MIDP) defines a Java runtime environment for cell phones, interactive pagers, and similar mass-produced, resource-constrained handheld devices... |

Learn how to write and deploy a servlet, and then how to hook up a MIDlet with the servlet. |

This second part of a two-part tutorial series on J2ME shifts the focus from MIDP's high-level user interface to the most important components of the low-level interface. You'll learn the basics of creating and working with the Canvas and Graphics classes. As with Part 1, you will learn about each component and build a MIDlet to demonstrate its capabilities. The tutorial will conclude with a brief overview of the Game API, introduced with MIDP 2.0. |
