One advantage to using a session bean is that later, if you want to write a
Swing client, you can do so and just have it call the same session bean
that your JSP is calling.
On the other hand, if that need ever arises, it wouldn't be too hard just
to write a session bean at that point. And if it doesn't, you've saved
some time and hassle! :-)

There is no need for a session bean in this scenario. This is just what the
Pet Store does for example. Also I don't see why it wouldn't be reuseable
to
any other servers if it is well designed (and documented). Finally you
could
wrap it in a Custom Tag so it could be reused by non Java programers as
well.

Subject: Please Clarify the Need for Session Beans
If I am just making simple reads from a data base to display
information in a JSP (a user profile for example), why should I use a
session EJB? Why not just make the reads in a data access layer, put
an object in the request and call the object in the JSP.
I understand that I would not have a "reusable component" that could
be deployed to other servers. But what are the other tradeoffs and
advantages?
Thanks!
