Introduction to Java EE

The Java Platform, Enterprise Edition (Java EE) is a collection of API specifications designed to work together when developing server-side, enterprise Java applications. Java EE is a standard; there are multiple implementations of the Java EE specifications. This fact prevents vendor lock-in since code developed against the Java EE specification can be deployed to any Java EE-compliant application server with minimal or no modifications.

Java EE is developed under the Java Community Process (JCP), an organization responsible for the development of Java technology. JCP members include Oracle (the current steward of the Java platform), and the Java community at large.
