Java ME , in particular MIDP and CLDC specifications and Mobile device hardware

Java is also referred to as a programming environment oriented to the server and it is based on a number of technologies which constitutes the Java 2 Enterprise Edition (J2EE . Such technologies include servlets JavaServer pages (JSPs , and Enterprise JavaBeans (EJBs . Nowadays , Java is officially known as Java 2 platform and it is divided into three distinct editions : Java 2 Enterprise Edition (J2EE , Java 2 Standard

Edition (J2SE , and Java 2 Micro Edition (J2ME . Java 2 Micro Edition (J2ME ) has three concepts , namely pros , configurations , and optional packages . All of them determine Java features applicable , available application programming interfaces , and the form in which applications are packaged . J2ME has two configurations : Connected Limited Device Configuration (CLDC ) and Connected Device Configuration (CDC . CLDC is designed for mobile devices with slow processors (Enrique Eric 2001 pp . 28- 45

There are two versions of CLDC : versions 1 .0 and 1 .1 . CLDC specifies the ability of Java virtual machine , a small subset of J2SE 1 .3 classes , and a set of application programming interfaces for output /input which is also called Generic Connection Framework . However , CLDC is limiting programming platform as it does not specify the user interface classes Hence , alternative classes that are defined by J2ME pro are required and such include MIDP to accomplish anything substantial . Java runtime environments for devices such as pagers , resource-challenged handheld devices , and cell phones...
