Enterprise JavaBeans ('EJB') is a managed, server-side component architecture for modular construction of enterprise applications.
The
EJB specification is one of several Java APIs in the Java
EE specification. EJB is a server-side model
that encapsulates the business logic of an application. The EJB
specification was originally developed in 1997 by IBM and later adopted
by Sun Microsystems .
The
EJB specification intends to provide a standard way to implement the
back-end 'business' code typically found in enterprise applications (as
opposed to 'front-end' interface code).
Such
code addresses the same types of problems, and solutions to these
problems are often repeatedly re-implemented by programmers. Enterprise
JavaBeans is intended to handle such common concerns
as persistence, transactional integrity, and security in a standard way,
leaving programmers free to concentrate on the particular problem at
hand.
