I'm now at chapter 5 of Mastering EJB 2nd edition, so i'm still new in this. I have been wondering about the real world applications that make use of EJB. Can anybody give me some real examples about the fields EJB is used for ?
Can we classify EJB as one of the web services like ebXML, SOAP, etc (i have no idea what these web services are) ?
If you know the links for infos that could help me, please reply them here, okay ? Thanks alot !

EJB's are most useful in transactional applications where many (thousands) of transactions are concluded at the same time.
Banking is a good example.Think of many people
using an ATM to withdraw,deposit or enquire
on their balances at once.The Container or
Application server manages the transactions
and ensures integrity.

There are many case studies posted on the java.sun.com web site giving areas of application where EJB has been used, ranging from the US military to the APE.
