In this sample chapter from the book “Enterprise J2ME“, Michael Yuan introduces you to OSGi programming and gives two complete example applications that run on PDA devices.

The Open Service Gateway initiative (OSGi) framework provides a Java technology-based lightweight (fully J2ME-compatible) container for dynamic software components. It handles the interactions between components and allows developers to remotely manage the entire application life cycle, including over-the-network deployment and updating. The OSGi framework was originally designed to fit the needs of pervasive devices, which need to run a variety of different software and to be managed remotely. Examples of such devices include smart home information hubs (for example, TV set-top boxes), automobile-mounted devices and even enterprise PDA devices. As more and more developers discover the power of OSGi, it has recently been used beyond the mobile embedded gateway context. For example, it has been selected as the next generation MicroKernel of the Eclipse IDE platform.
