As many of you have learned, J2ME programming is filled with some interesting challenges not faced when programming your Desktop or Server systems. When they said Limited Device, I think many people were surprised by how limited, limited really is. To assist in with this problem, we would like to introduce the Reduce, Reuse and Recycle series of articles. Over the next while, we will take a look at a number algorithms and approaches that can be used to help deal with the limitations in many of these devices. In particular, we will look to focus on performance and memory usage, as these are the two most common areas that developers experience problems.

It is unnecessary to say that many developers are using J2ME to develop their games and enterprise applications to take advantage of the \'write once, run anywhere\' paradigm. Who am I do bash this very noble intention, but phones unlike many other types of computer, have no uniform set of memory and storage parameters that improves over time.

This series of articles describes the role of Java 2 Micro Edition (J2ME) devices in Peer-to-Peer (P2P) computing. We will take JXTA (visit www.jxta.org for details) as an example P2P network and show why, when, and how to use J2ME as a JXTA peer.In the first article of this series, we will describe how JXTA has defined the functionality and characteristics of a virtual network topology that can work over any existing network technology (such as IEEE 802.11-based LANs, and the IP-based Internet). We will then discuss the special features that JXTA has achieved by defining a virtual network overlay on top of existing technologies.

In the first article of this series, we answered several common questions regarding persistent storage (Record Management System) within MIDP:Can record stores be shared among MIDlets? Can record id\'s be re-used? How do you use the Enumeration class?We concluded the previous article with a MIDlet that showed how one might use the Enumeration class to move through records in persistent storage. As an extension of that example, this article will address how to use an enumeration to sort and search records within the record store.

A little Java might be just what you need to maximize the benefits of a wireless implementation, in particular, J2ME(tm) and the MIDP(tm) standard. Only a couple of years ago IT managers that were considering a wireless data implementation strategy would have probably considered one of two options.The second choice would have been to embrace and invest in a proprietary platform. The benefits with this approach were better performance and greater security. The downside included having to train developers on the platform or pay for the expertise from a systems integrator.

The architecture of J2ME and demonstrates the various specifications for programming Java applications. Through the use of a tutorial application and various programming examples, the common elements of most applications, namely user interface, event handling, data storage, networking, and input/output are examined. Also covered are design considerations when building software for resource-constrained devices as well as J2ME competition and associated technologies in these devices.

Wireless Java consists primarily of the Java 2ME (Micro Editon) platform with its API and tools like the Wireless Java Toolkit. In the J2ME, there\'s the Foundation Profile MIDP PersonalJava Configurations. The Foundation Profile lets you write applications for small wireless devices that do not support a GUI. Mobile Information Device Profile (MIDP) is a more advanced set of APIs including MIDlets (wireless-optimized servlets) and other instructions for downloadable applications and services for network-connectable, battery-operated mobile handheld devices such as cell phones, two-way pagers, and PalmPilots.

This article contains everything you need to know to get started developing in the Java 2 Platform, Micro Edition (J2ME) environment. You\'ll learn how to install the development tools, how to write your first J2ME application, how to build it, and how to test the application in an emulator. The application you\'ll build, a MIDlet, runs on implementations of the Mobile Information Device Profile, one of the J2ME specifications.

The article, structured in two parts, tries to establish a common ground for I/O and network operations on BREW and encapsulate this commonality in a framework. Such a framework is used in J2ME to insulate the developer of protocol implementation details, to offer the needed flexibility in supporting new devices and protocols, as well as to define a uniform way of accessing different resources. These reasons are compelling enough to investigate a similar approach for BREW—with an additional challenge: BREW is asynchronous.

This tutorial explains how to write multi-player games for MIDP phones. It describes the technologies that are available to support multi-player games, and shows what kinds of games are possible with these technologies.
