Professional Java Mobile Programming

J2ME is an exciting set of technologies that provide integration of Java with wireless devices, and bring Java back to its design roots. Wireless device types, operating systems, and networks will proliferate, but Java provides a unifying programming platform for these devices.

The potential of a flexible and secure run-time environment on these new devices is immense. Mobile code, context or location-sensitive web-based services, and inter-device communication are all possible between differing devices.

The recognition that 'one size doesn't fit all', however, and the resulting introduction of configurations and profiles, is confusing. Java is still 'write once, test everywhere,' in developers' minds. This book answers in one volume the need for a detailed examination of the differences and similarities between implementations of J2ME.

Currently, deployable context based services are only possible through WAP. The book covers this exciting new area of providing location-based services.
