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.
