NetBeans adds ties to devices, ALM
Sun Microsystems will advance the NetBeans open source tools platform on devices and the application lifecycle management (ALM) front. Sun and the NetBeans community are announcing the availability of NetBeans Mobility Pack for Connected Device Configuration (CDC) 5.5 for developing applications for devices such as full-featured smart phones.

Push messages that automatically launch a Java mobile application
Pushing messages to a mobile device from a server and automatically forcing a pre-installed application to wake up and do some processing is sometimes important for an enterprise mobile application. Java Micro Edition applications that use Mobile Information Device Profile 2.0 can have this feature using the push registry, with Short Message Service (SMS) used as the protocol for pushing messages, and, in this article, Srijeeb Roy shows how.

Let the mobile games begin, Part 2
J2ME (Java 2 Platform, Micro Edition) and .Net Compact Framework follow different design philosophies and target different developer communities. However, both have important places in the future world of pervasive computing. Developers must choose and mix the right tools for real-world challenges. In this article, Michael Juntao Yuan uses a mobile driving-directions example to discuss how the Java and .Net platforms work together from end to end with the help of XML Web services. Through the code examples, he also illustrates each platform's key benefits and problems.

Let the mobile games begin, Part 1
Java 2 Platform, Micro Edition (J2ME) is by far the most advanced and successful mobile application platform available today. However, with mobile commerce growing into a multibillion-dollar industry, serious competition is on the horizon from Microsoft. Microsoft's latest mobile commerce offering is the .Net Compact Framework (.Net CF). What exactly is .Net CF? How does it measure up to J2ME? As Java developers, what can we learn from it to better compete? In this two-part series, Michael Juntao Yuan presents an objective and comprehensive comparison between the two platforms. If you work in a predominantly Microsoft shop, the .Net CF and Visual Studio .Net tools will definitely help you port enterprise applications to mobile devices. .Net CF leverages the large community of existing Windows developers and helps companies lower development costs. However, if you are in a heterogeneous environment or need a real pervasive solution that works on low-end devices, J2ME is the hands-down winner. In the enterprise world, important J2ME vendors opt for service gateway-based application paradigms, while .Net CF is still too young for any significant third-party mobile middleware to emerge.

Data security in mobile Java applications
The recent release of MIDP (Mobile Information Device Profile) features a major improvement over version 1.0. Version 2.0 includes enhanced mobile code and application security through a well-defined security manager and provisioning process. On the data and communication security front, MIDP 2.0 makes HTTPS support mandatory. HTTPS is currently the most widely used data security protocol in PersonalJava and J2ME/CDC (Java 2 Platform, Micro Edition/Connected Device Configuration) applications.

Best tools for mobile application development
A new technology's successful adoption often depends on its development tools. Good tools help new developers more easily get started and make experienced developers more productive. For instance, the success of Microsoft's programming environment is closely associated with the success of its Visual Studio tools.
