Understanding Profiles Profiles collect essential APIs for building the most fundamental of applications across a family of devices. The most well known profile by far is the MIDP, which powers mobile phones and sits atop the CLDC. Equally important is the Foundation Profile, which is analogous to the MIDP for providing application support classes. Unlike CLDC-based devices, however, CDC-based devices typically also include either the Personal Basis Profile or the Personal Profile, or both, to provide user-interface support for applications.

Figure 1-1. The relationship between configurations, profiles, and packages in Java ME Each instance of a configuration, profile, or package should have as its basis one or more Java Specification Requests (JSRs) that document the purpose and interface for the Java extension in question. Appendix A summarizes the JSRs relevant to Java ME that define functionality discussed in this book. Today, there are two configurations within Java ME: the Connected Limited Device Configuration (CLDC) and the Connected Device Configuration (CDC).

It defines a Java environment based on the Java K virtual machine (KVM), a modified version of the JVM that has been specially tuned to operate on low-power devices with a 16- or 32-bit processor and as little as 192KB of RAM. The most common deployment of the CLDC, as I’ve already noted, is in the billions of Java-enabled cell phones that have shipped in the last several years. info CHAPTER 1 ■ MAPPING THE JAVA JUNGLE A device with the CLDC is quite primitive; it’s missing many of the classes you’d expect to find that permit application development (such as user-interface widgets, network connectivity, and the like).
