J2ee:

The platform was known as Java 2 Platform, Enterprise Edition or J2EE until the name was changed to Java EE in version 5. The current version is called Java EE 5. The previous version is called J2EE 1.4. Java EE is defined by its specification. As with other Java Community Process specifications, Java EE is also considered informally to be a standard since providers must agree to certain conformance requirements in order to declare their products as Java EE compliant; albeit with no ISO or ECMA standard.
