Title: RE: EJB vs Servlets
This strikes me as a straw-man argument.
There is no reason that servlet code must use JDBC directly. There are
many object-wrapper products available that work similarly to CMP beans; such
products predate EJB by a long, long time.

You seem to be missing the big picture here. With using a Servlet engine for

may have partitioned your logic up in the servlet container envirionment

Hello Reddy,
I agree with you in some points. Yes, complex OR mapping is solved in
2.0, but as you said is a draft. I won't risk put it into production
right now (we have to finish the project by Octuber 17).
About SQL, again I agree with you. I was using BMP EJB until I found

I've considered using EJB's a number of times for various projects I'm involved in, but every time, I have to admit to myself that it's more for the fun and coolness factor, than any real 'need' to use EJB's.
In every case, I was able to implement a solution using
You should read up on J2EE so you can understand what separation of

Might there be some benefit to using EJBs over servlets alone if you want to
support various modes of connectivity to your business logic (e.g., standalone
clients using JMS/CORBA/RMI in addition to web clients).
Just my two cents worth.

You are talking about legacy support. I agree there. I haven't read the full

I would say that using J2EE architecture and EJB is most useful if you don't have
specific performance needs. When you don't have leeway on performance
you have to bite the bullet and use whatever gives you the performance you need.
Obviously EJB2.0 OR mapping is a huge key, this allows the
