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?

Yes. JavaBeans are just regular classes that follow certain coding patterns.

what advantage would there be to using Java Beans? Are Java Beans

JSPs can use beans, via, for example, the <jsp:useBean> tag.

One of several patterns is to use a bean as a value object to hold results
from the middleware. The JSP can display results held in such a value object.

still a supported technology and can I afford to ignore it?

It's not a technology, it's a technique, and no.
