Question :What is the difference between creating a distributed application using
RMI and using a EJB architecture? (EJB)
Answer :It is possible to create the same application using RMI and EJB. But in
case of EJB the container provides the requisite services to the component
if we use the proper syntax. It thus helps in easier development and lesser
error and use of proven code and methodology. But the investment on
application server is mandatory in that case. But this investment is
warranted because it results in less complex and maintainable code to the
client, which is what the end client wants. Almost all the leading
application servers provide load balancing and performance tuning
techniques. In case of RMI we have to code the services and include in the
program the way to invoke these services.
