The Java 2 Platform, Enterprise Edition (J2EE) defines the standard for developing multitier enterprise applications.The J2EE platform takes advantage of many features of the Java 2 Platform, Standard Edition (J2SE), such as “Write Once, Run Anywhere” portability, JDBC API for database access, CORBA technology for interaction with existing enterprise resources, and a security model that protects data even in internet applications.
The success of the J2EE platform in the enterprise continues to rise as more than two-thirds of enterprise software development managers use the J2EE platform to develop and deploy their applications. With addition of interoperable Web services and other new features in version 1.4, the J2EE platform will continue to be the industry standard for enterprise solutions for many years to come.
The Enterprise Java BluePrints for the J2EE platform describe the J2EE application model and best practices for using the J2EE platform.
In addition to providing support for Enterprise JavaBeans and Java Servlets and JavaServer Pages components and Web services APIs, the J2EE platform specification defines a number of services for use by J2EE components.
