With Nokia alone announcing deployment of 150 million phones running Sun's J2ME and Mobile Information Device Profile (MIDP), developer interest in these technologies is enormous. Now, there's an authoritative, example-rich technical resource that will enable every Java developer to build robust applications for any J2ME mobile device -- fast. Written by one of the world's most experienced Java developers and trainers, this hands-on book teaches J2ME and MIDP using more than 50 well-designed examples -- all of them clearly commented, thoroughly explained, and available for download on the Web. Core J2ME Technology covers everything a developer needs to get results. John Muchow begins with an overview of the J2ME, including configurations and profiles; then walks you through creating your complete J2ME development environment -- from downloading J2ME to troubleshooting. The book then provides exhaustive coverage of the MIDP programming interface: the basics of the MIDlet application lifecycle; event handling; low-level components; persistent storage; networking (including communication with servlets and session management); and more. The book also contains comprehensive references to both key elements of J2ME: MIDP and the Connected Limited Device Configuration (CLDC) specification. For all experienced Java developers who want to create mobile applications with J2ME.
