J2ME, a leading platform in the mobile application market, provides more than 150 million cell phone users a powerful new level of connectivity. Currently, there are 200 J2ME-enabled handset models available from 70 manufacturers, and users perform more than 10 million downloads every month. It is projected that J2ME-enabled handsets will completely dominate the market by 2006, with more than 1 billion in use worldwide. However, a J2ME-enabled device has its limitations, namely available memory and processor power. An application must combine local and remote data processing to deliver meaningful results in a timely manner. The solution is a connected MIDlet, which handles the collection and display of data locally, but delegates any processor-intensive tasks to a remote ... (more)

One of the most powerful aspects of J2ME is connected mobility: you're no longer tied to your desk to accomplish many vital tasks. You can carry everything you need in your shirt pocket, send an e-mail while standing in line at the grocery store, or check the latest stock figures while at a baseball game. There is nothing new about distributed applications; people have been using them f... (more)

Building A Connected MIDlet

This article is the second in a two-part series devoted to developing a connected MIDlet. In the first part of the series, we designed and built a functional application that collected a string from the user, established a connection to a remote server, sent and received data along that connection, and then presented the result to the user. In this article, we'll refine the design of the... (more)
