J2EE stands for Java 2 Platform, Enterprise Edition, a powerful form of the Java platform that includes routines and subroutines designed for servers and mainframes. It allows cross-platform communication and is available for free.
J2EE is another acronym in the computing world. This stands for Java 2 Platform, Enterprise Edition. Its meaning will become clear once its lineage is traced. First of all, Java is a programming language developed by Sun Microsystems, one of the giants in the sector. The Java platform is a virtual machine, a doppelganger of a processor that translates computer instructions into functions.
The Java language is such that it allows cross-platform communication between multiple types of devices. For example, a programmer can develop Java code on a desktop computer and expect it to run on other computers, routers, and even cell phones, as long as those devices are Java-enabled. This portability is described by the Sun acronym WORA, which stands for “Write Once, Run Anywhere”. A large number of mainframes, computers, cell phones and other electronic devices run on the Java platform.
The 2 in the acronym J2EE stands for Version 2. As with many software applications, J2EE is Java Platform Version 2. Actually, the number 2 is often dropped nowadays, so J2EE becomes Java EE. Traditionally, though, it’s still J2EE.
Now, onto the EE. It stands for Enterprise Edition, which is a powerful form of the Java platform. Sun has created three editions so far. The most accurate is the Micro Edition, used for cell phones and PDAs. Following the form, this can be abbreviated as Java ME.
The intermediate edition is the Standard Edition, which can be run on mobile devices, laptops and desktop computers. The abbreviated name of this edition is Java SE. Moving up the pyramid, we finally come to the Enterprise Edition, which includes all the features of the Micro Edition and the Standard Edition and also features routines and subroutines designed specifically for servers and mainframes.
One major advantage of J2EE, despite taking on such a powerful set of source code, is that it is available for free. You can download it now from the Sun Microsystems website. There are also third-party open source tools to help you, including Apache Tomcat and JBoss. However, unless you’re running your own server or mainframe system with multiple workstations, you’re unlikely to encounter or need J2EE. However, it’s good to know what these things mean.
