J2EE Java 2 Platform, Enterprise Edition (J2EE) is a set of related specifications and documentation that define an enterprise-level computing architecture using the Java platform. Core components of J2EE are Enterprise JavaBeans (EJB), JavaServer Pages (JSP) and Java servlets and a host of interfaces—including JDBC, JNDI, JMS, and JTA—for linking to the information resources of an enterprise.
Dedicated to enterprise software development, this architecture simplifies the development of component-based multitier applications and Web services. Using J2EE, applications that are portable, scalable, and interoperable can be built easily.
