Enable pervasive computing with Java

The Green Project created Java specifically for an embedded device, a handheld wireless PDA (persnal digital assistant) that was never released as a product. However, Java was launched as a new Internet language. Over time, it became popular for building desktop applications, Web services, and ubiquitous systems, partly because of its "write once, run anywhere" promise. There's no doubt that Java and PDAs are a powerful combination. In Java Development on PDAs: Building Applications for PocketPC and Palm Devices, the author writes that Java developers often have a preconception that having to choose a hardware platform is a concern of the past, since Java runs on any platform. The author discusses portability issues between the PocketPC and PalmOS devices.
