EJBs are more costlier when compared to beans, but when it comes to systems which need to have transactions and other services (mostky transactions) EJB is the best answer.

EJB container takes care of the transactions making it transperent to the developer. Developer can concentrate on the business logic leaving behind the complex system programing task.

It also pulls the Business logic from your infrastrucutre logic like database pooling etc. It aids component based development and leaves the basic functionalitues to the developer.

Secondly they make Java Beans remotely available. Since all EJBs are invoked thorugh JNDI and RMI they can be deployed on a different machine as against the client. This makes it easy for distributed software systems.

Thirdly, with recent clustering technolgies in the J2EE world, it improves avaialability of the business services very high.
