EJB Integration
Introduction:-
Enterprise Java Beans (EJB) can be used extensively in Spring’s environment. The
transparent support available in Spring for using the Stateless and the
Stateful Session Beans in Spring.As a lightweight container, Spring is
often considered an EJB replacement. We do believe that for many if not most
applications and use cases, Spring as a container, combined with its rich
supporting functionality in the area of transactions, ORM and JDBC
access, is a better choice than implementing equivalent functionality via an EJB
container and EJBs.
It is important to note that using Spring does not prevent you from using EJBs.
Spring makes it much easier to access EJBs and implement EJBs and functionality
within them. Additionally, using Spring to access services provided by EJBs
allows the implementation of those services to later transparently be switched
between local EJB, remote EJB, or POJO (plain old Java object) variants,
without the client code having to be changed.
