J2EE architecutre

[SJ Rao]

Hi,
We have created an web based application using JSP and Javabeans. We haven't used servlets or EJBs.
This application is basically a planning tool & which has lots of equations & computations.
Is this a good way of developing an application, or is it necessary that we need to use servlets & EJBs to achieve J2EE architecture.
Since I cannot categorize it as MVC architecture, which architecture does this application belong to, because when I am giving a demo to the client, I should be able to explain them.
Thanks
SJ
