That's a big subject! You may want to start with the article titled "introduction" that's linked in the JavaRanch J2EE FAQ.

Enterprise beans are there to make your job easy,
you can concentrate on your business logic instead of worrying
about for transaction, security all those stuff. everything your ejb container will take care of it. Thats where the enterprise beans playing a great role.

Baskar is correct in what EJBs aim for.
But the jury is still out as to whether or not they really make developer's jobs easier, or if the whole concept just adds layers of stuff that
get in the way of making useful code.

Better, Faster, lighter Java makes a strong case that EJB's don't really deliver.
