Enabling links according to user's authorization

Hi everyone,

We have a web application running on Websphere Application Server V6.
Say i have a jsp page that enables working on Student details.
This jsp page enables users to view, insert, update or delete student records.
Now, some users can only use the 'View' link, otheres can also use 'Insert' link, and some other users can only update.

From what i know, i can hold a DB table that indicates for each user and table - which operations are allowed.
But, my question is - what is the right way to do that on the JSP page?
Do i call this security table on each page load and hide the anauthorized links? Or, do always show all the links and just let the database throw an exception and give a message to the user, when he/she presses an anauthorized link? Or is there a third and better way?

Thanks
Rivka

Rivka,
A better approach may be to use a taglib to enforce the page level access control. See the Authorization Enforcer pattern in Chapter 9 for a description and sample code on how to do this.
