If any of these requirements hold for your application :-

1.the application must be scalable and distributable
2.Transactions will be required to ensure data integrity
3.the application will have a variety of clients

ejb is a 3-tire architecture (client,server,database).servlet  is simple client server architecture i.e 2-tire.

By using ejb, we are seperating the business logic. This is used when we have distributed environment where the client can access the remote object as if it were in the same local machine.
