MahmoudOctober 2002 Developers usually build, test, and evaluate an application on a platform similar to the one on which it will be deployed and run. Development of wireless Java applications is more challenging because they typically are developed on one platform (such as Solaris or MS Windows) but deployed on a totally different one (such as a cell phone or PDA). One consequence is that, while emulators enable developers to do some of their testing on the development platform, ultimately they must test and evaluate the application in the very different environment of a live wireless network. The aim of this article is to show you the different ways you can download local and network applications to J2ME-enabled devices, for both testing and final deployment. After a brief review of wireless Java applications and their development life-cycle, the article shows you how to: Deploy wireless applications remotely Download local and remotely deployed applications Download applications over the air Wireless Java Applications Wireless Java applications fall into two broad categories: Local applications (also called stand-alone applications) perform all their operations on a handheld wireless device and need no access to external data sources through a wireless network. Examples include calculators and single-player games. Network applications consist of some components running on a wireless device and others running on a network, and thus depend on access to external resources. An example would be an email application, with a client residing on a wireless phone that interacts with a Simple Mail Transfer Protocol (SMTP) server to send messages. Although these two types of applications are different, they are deployed in the same way.
