Question: What is the difference between EJB and RMI

Answer: Both of them are java solution for distributed computing.



RMI offers remote access to an object running in another JVM and no other services.



But EJB offers far more services than RMI apart from remote method calling. EJB leverages this remote-object feature of RMI and ORB (RMI-IIOP) which can be called by any COBRA client, but also provides other services such as persistence, transaction management, security, resource management, object pooling and messaging.
