J2ME Tech Tips
Applications written for the Mobile Information Device Profile (MIDP) are rarely stand-alone applications. Normally, there's some part of the application that involves calling server-side code for processing. In MIDP 1.0, the only way to portably invoke server-side code is by making HTTP requests to a servlet running in an external Web server.

Are Device Independent Wireless Internet Applications Possible?
As 2003 approaches,the point at which wireless Web users are expected to outnumber wireline users, there's little talk of the challenge to build wireless applications for them, applications to reach reach all of these users (as opposed to segments of these users whose devices support proprietary protocols).

The faces of wireless, Part 1
Where do developers find the guidance they need to make intelligent choices within a giddying expanse of possibilities and obstacles? Somewhere, an answer falls in the spectrum of professionals who are intimately acquainted with wireless technology, from the developer to the CEO to the analyst, and beyond. Here's what they have to say about pinning hopes to -- and leaping between -- platforms.

The faces of wireless, Part 2
Security is a "make it or break it" proposition in the realm of wireless applications. Not only do the same risks of cracks and viruses affect wireless systems just as they do in the wired world, multiple levels of vulnerabilities come into play when leaving the hard line behind, from interoperability issues down to securing the device itself. Whether the standpoint is from a security technology provider or a B2B software application provider, one thing is certain: Success of any rollout will hinge on how secure the user feels.

The faces of wireless, Part 3
Wireless users have shouted, and the providers are answering. With the number of wireless customers growing at the speed of an arson fire, the companies providing portals have to focus on developing the perfect one to meet the needs. Here's the scoop on developing the optimal portal for your needs, and having it work with the device you prefer.

The faces of wireless, Part 4 Wireless for sheer entertainment
The Internet games have begun, and a variety of companies, from online publishers to network carriers to PDA and cell phone manufacturers, are looking for more developers than ever to create a wide range of mobile and wireless entertainment products. Taking a cue from the Asian-Pacific market for mobile entertainment, companies in the U.S. are gearing up not only to provide powerful devices and technologies for better play, but also to publish games that have a viral effect.

The faces of wireless, Part 5 The future and the flings in between
Will it take a "killer app" to make wireless soar (in the U.S.)? Or will we all have to wait two or more years before a transparent 3G network lets applications take off? Signs of success are emerging from the whirlwind that moves through enterprises to consumers, across improving devices and networks, through open standards. They are successful applications that make economic sense to users, along with apps that are just plain fun.

Parsing XML with J2ME
You might at some point have a need to parse XML as part of your J2ME application. Due to the constraints of J2ME, you're going to need a small parser. There are currently three choices, NanoXML, TinyXML, and kXML. All are open source, but NanoXML has the least restrictive license.
