In his previous book, Java 2 Micro Edition (0-471-39065-8), Eric Giguere showed why Sun's J2ME is fast becoming the dominant language for all handheld devices. In this new book, the Ortiz-Giguere team explains how to use the J2ME Mobile Information Device Profile (MIDP) to write Java applications for wireless devices like cell phones and two-way pagers as well as more powerful devices like the Palm VII. The authors begin with a basic tutorial on J2ME, then quickly move on to explain how to use MIDP to write full-featured applications for cell phones and pagers. Using real case studies and code, they walk developers through all the necessary topics, including GUIs, client/server and peer-to-peer communications, HTTP, XML, databases, WAP, security issues, MIDP and J2EE in the Enterprise and much more.
