Java Enterprise Edition Technology

The Java EE is a related set of specifications that define the entire Web-enabled application, from the browser to the server and all the components in between.

The Java EE Application Model defines a multi-tiered distributed application:

• The Web browser is used for the application user interface.
• A middle tier that may implement the application work flow logic.
• An Enterprise Information Systems tier that may implement the application business rules and database operations.

The Java EE specification is a collection of several related specifications. The following is a partial list of specifications that are encompassed by the Java EE specification:

• Java Platform, Standard Edition (Java SE)
• Common Annotations for the Java Platform
• Java Server Pages (JSP)
• Java Servlet
• Enterprise JavaBeans (EJB)
• Java Database Connectivity (JDBC)
• Java Naming and Directory Interface (JNDI)
• Java Transaction API (JTA)
• Java API for XML-Based Web Services (JAX-WS)

Since these specifications are based on Java technology, Java EE applications are hardware platform and operating system independent.
