Hi, RMI, CORBA and EJB provide technologies and mechanism to implement complex
3-tier application. Of coz, you also can use java.net and other relationcal
tech. to implement 3 or 2 tier application, but you have to do lots of distrubuted
work yourself.

EJB steps on RMI, i mean when you make a request to EJB it is done by RMI.
RMI is a Java remote method invocation. No other languages support that method.

If you want to build services that would be accessed not only from Java clients,
you MUST write these services to support CORBA invocation.

If you do this, your services would be accessed from languages like VB, Delphi,
....

Hai

EJB is the very strong in multi-tier applications.
Why because in EJB devolopment and deployment at server side only.
Where as in CORBA and RMI case not like that..
