Installation and use of J2ME development environment

J2ME (Java 2 Micro Edition) is now a mainstream, universal mobile phone program Development technology, in the actual development of the extensive use of the process. and mobile phone program development as a new area of software development, the demand for talent and products is far from being satisfied, so mobile phone program development technology has become the hottest, but also the development of a bright future technology. This paper introduces the first link of J2ME technology development-the installation and practical use of the development environment.

J2ME Technology as a general technology, targeted at the main areas of consumer electronics, including set-top boxes, car equipment, videophone, mobile phones and other equipment, the following only describes the J2ME technology for mobile phone application development tools used in the type.

In the actual environment, mobile phone models and a wide range of performance and characteristics of each cell are different, and the mainstream of mobile phone manufacturers will be in the standard J2ME technology based on some of their own unique functions to facilitate the development of programmers, Therefore, the development of J2ME mobile Phone program development environment is divided into the following two major categories:

1. Common development tools

Common development tools can develop programs that run on all mobile phones that support J2ME technology. In the actual development process is mainly used to develop and mobile phone screen size unrelated to the program and no dedicated development tools for mobile phone programs.

General development tools are mainly sun company J2ME Wireless Toolkit, now the latest version is 2.3beta, generally using the tool's stable version 2.2, download the address as follows:

2, special development tools (manufacturer development tools)

Special-purpose development tools refer to the specialized development packages developed by each handset manufacturer for its own model cell phone. Basically, the mainstream handset manufacturers have their own dedicated development tools to facilitate programmers to develop dedicated mobile phone programs, and provide their own model of the simulator, to facilitate the programmer in the computer for practical simulation.

Proprietary development tools are generally available to developers for free, but they generally need to be registered when downloading.

The special development tool according to the handset model mainly has the following several:

Nokia Nokia developers Suite for J2ME

Nokia series of mobile phone development tools, the latest version is currently 3.0. Nokia mobile phone in the domestic market share is relatively high, and for J2ME development support is also relatively good, so the current J2ME development in the use of relatively high frequency of manufacturers development tools.

Motorola (Motorola) 's J2ME SDK

The latest version of the tool is 5.2.1, but the SDK does not support the IDE very well.

SonyEricsson (Sony Ericsson) J2ME SDK

The latest version of the tool is 2.2.3, although SonyEricsson market share is not high, but for the 3D support is better.

The following is an example of Sun's J2ME Wireless Toolkit 2.2, which describes the installation and use of the J2ME development environment. Because there are more users of Windows operating systems, the following is an introduction to installation and use on Windows platforms.
