"Learning Wireless Java". (Relevant Network Literature).Although it may seem as if Java programmers are trying to take over the world, the truth is that Java's versatility leads it naturally into new frontiers of technology where, rather than encroaching on the turf of existing technologies, Java has a way of complementing them. Now that Java has come to the wireless arena with the advent of the Java 2. Platform, Micro Edition (J2ME (Java 2 Platform, Micro Edition) A version of Java 2 for cellphones, PDAs and consumer appliances. J2ME uses the K Virtual Machine (KVM), a specialized Java interpreter for devices with limited memory. ) from Sun Microsystems, the possibilities for new wireless applications and over-the-air distribution models for handheld devices are beckoning to Java programmers. "Learning Wireless Java" by Qusay H. Mahmoud was written to bring these programmers up to speed with wireless Java as quickly as possible. According to Mahoud, there are numerous advantages to using Java for wireless devices, including the dynamic download of applications that will run even when the device (say, a cell phone) is disconnected from the wireless network or out of the coverage area. A second advantage is that wireless Java provides support for disconnected operations. And, true to Java in general, wireless Java applications are platform-independent: they run on all wireless Java-enabled devices in the same manner. In "Learning Wireless Java," Mahoud introduces the Connected Limited Device configuration The Connected Limited Device Configuration (CLDC) is a specification of a framework for Java ME applications targeted at devices with very limited resources such as pagers and mobile phones. The CLDC was developed under the Java Community Process as JSR 30 (CLDC 1. (CLDC See J2ME. ) and the Mobile Information Device Profile Mobile Information Device Profile (MIDP) is a specification published for the use of Java on embedded devices such as mobile phones and PDAs. MIDP is part of the Java Platform, Micro Edition (Java ME) framework and sits on top of Connected Limited Device Configuration, a set (MIDP (Mobile Information Device Profile) A programming interface (API) for cellphones and pagers for the Java 2 Platform, Micro Edition (J2ME). It provides support for a graphical interface, networking and storage of persistent data for "MID Profile" applications, ) for developing wireless applications, as well as tips and tricks for using Sun Microsystenis' lightweight K Virtual machine (KVM).
