Right, Java 2 is simply the 1.4.x releases. I believe it started with the release of 1.2, and just stuck. I'm not entirely sure, so if I'm wrong, don't point your finger and should "Ah ha!"That said, the J2EE is the enterprise edition. It's for databases and corporate works.

According to SUN, java is mainly divided into:

J2SE:Java 2 Platform, Standard Edition (J2SE) provides a complete environment for applications development on desktops and servers. It also serves as the foundation for the Java 2 Platform, Enterprise Edition (J2EE) and Java Web Services.

 

J2ME:The Micro Edition of the Java 2 Platform provides an application environment that specifically addresses the needs of commodities in the vast and rapidly growing consumer and embedded space, including mobile phones, pagers, personal digital assistants, set-top boxes, and vehicle telematics systems.

 

J2EE:Java 2 Platform, Enterprise Edition (J2EE) defines the standard for developing component-based multitier enterprise applications. Features include Web services support and development tools (SDK).

 

Since Java1.2, Java is renamed to Java2. Now, Java1.5(Tiger) is released, it is also called "Java5.0".
