should my web app use java beans for business logic, or regular javaclasses

[terry433iid]

I am developing a web application to allow users setup a complete test
environment for their specific needs :-
- hardware
- users
- projects
- tests

So the app would allow users to create a project (say nfsv4)
whereby they would allocate 3 lab systems to run an nfsv4 testsuite
(called nfsv4_test).
So in the classic MVC model the backend would be SQL database with
tables for users, hardware, tests, projects. The front end would be
all JSP for adding/monitoring projects or users or tests, and it is
the middle portion that I am unsure about. I can use regular java
classes here to code the business logic ..... or do I use Java beans?
what advantage would there be to using Java Beans? Are Java Beans
still a supported technology and can I afford to ignore it?
