[Rakesh s Verma]

Hi guys,
I want to know what is so special about EJB technologies?
What on the basic thing can we achieve with the help of EJB?
Is there any other similar technologies in the market yet?
Is the roal of EJB is to exchange data in an OO manner?
if so XML is so widely used..then why to use EJB!..just because it is written in java!!!
What is the most beautiful concept in EJB...if any!!

Please help big guys..
I need to clear it in my mind before I begin with it....

It is a way of leveraging the application server for scalability, performance, transaction, security, etc.

Is there any other similar technologies in the market yet?

Spring does most of the things that EJB does.

Is the roal of EJB is to exchange data in an OO manner?
Not really. You can do that with just Java. Check out the J2EE Tutorial for Sun for more details about what EJB is all about.

if so XML is so widely used..then why to use EJB!..just because it is written in java!!!
XML is not a competitor of EJB.
