ejb and rmi

[sumit malik]

hi to all,
can anybody tell me the basic difference between RMI and EJB ..and why EJB is preferred...

Hi,
Java RMI is a protocol used to communicate method invocations over a network and does not provide services(you have to hard code it) like declarative transaction control, security, scalability, load balancing, fail over , etc.
EJB is a component specification that uses RMI to communicate method invocations over a network and also provides services(container implementation) to handle transactions, security, etc.
