What is Java EE 5?

Latest from Sun Microsystems,the name of the Java platform for the enterprise has been simplified. Formerly, the platform was known as Java 2 Platform, Enterprise Edition (J2EE), and specific versions had flavors such as J2EE 1.4. The "2" is dropped from the name, as well as the dot number.
