EJB 3.0 architecture

This topic provides a high-level overview of the distributed component architecture defined in the Sun Microsystems Enterprise JavaBeans™ (EJB) version 3.0 architecture specification.

Enterprise JavaBeans is a standard server-side component model for distributed business applications. The EJB specification is part of the Java™ Platform Enterprise Edition.

EJB 3.0 makes it much easier to develop EJBs, using annotations rather than the complex deployment descriptors used in version 2.x. The use of home and remote interfaces and the ejb-jar.xml file are also no longer required in this release. They are replaced with a business interface and a bean class that implements the interface.

For more information about EJB 3.0 specification go to the following Web site: https://java.sun.com
