What is J2EE?

J2EE stands for Java 2 Platform, Enterprise Edition, a programming language developed by Sun Microsystems. The Java Platform is a virtual machine, a processor look-alike that translates computerized instructions into functions.
Java language allows cross-platform communication between various kinds of devices. Java portability “WORA” means Write once run anywhere, well for example if programmers develop code on a desktop PC expects it to run even on mobile phones as long as the device is java-enabled. Now you can see that many electronic devices operate using java platforms.
Enterprise Edition, on the other hand is a powerful form of the Java Platform. Sun has created three editions so far, the J2EE, J2ME (pda’s) and J2SE (mobile, laptops and desktop). J2EE is available for free; it can easily download from the Sun Microsystems website.
