EJB are deployable,reuseable,server-side components. The components are usually purchsed from different vendors. ie. different components purchsed from different vendors are all integrated and focussed on solving a complex business problem.The components are ready made by vendors so the application developers can spend less time on development of the software.

The mainusage of EJB's is :::::;;;;;;to maintain abstraction b/w database to controller component in MVCand those provide more reusabillity.And it provide loosly coupling between client to databaseand no need connet databae directly ,container provide more services to connect database.and those provide more security through JAASand provide asynchronous messaging, which is powerful machanism now a days.and it is purely vendor indipendentthanks.

The EJB architecture is build upon the DCOM mechanism. So The bean class  can be accessable by across the network and it can be reused anywhere.

I would suggest everyone to check with any one because many people who might be novice to Java might think that the answer is correct...so please refrain from posting half correct answers

Ejb components are based on Distributed Objects.You can achieve distributed objects using many technologies including the OMG's CORBA,Microsoft's DCOM, SUN's java RMI-IIOP.
