JEE (J2EE is an outdated name for it) is not an application, it is a framework for building applications. Any particular application built with it can have any number of layers/tiers. A common separation is the 3-tier approach: a view layer, a business layer, and a data layer (or persistence or integration layer).

Explain what? It's a big topic that can't be explained in full in a forum like this; you can start reading up on it at Multitier_architecture.
