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 in putting 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 different devices.

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

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

This book is for corporate developers who need to extend enterprise applications to serve mobile devices and for developers who need to get up to speed on this new technology quickly. This book gives you examples of how this is done using Java APIs, ranging from servlets, MIDP, the JavaCard SDK, JavaPhone and others.
