Subject Re: method of implementing a 'login' section in a site
Date Tue, 09 Sep 2003 22:11:12 GMT
Well, what I can tell you what I've done, and then you're free to choose
(what a nice thing freedom...). I authenticated the user against a database;
if the user is authenticated, then I set a session attribute like (type
String): isUserAuthenticated.

Then, I wrote two custom tags (isUserAuthenticated, isNotUserAuthenticated)
which respectively executed the code within a <block></block> depending
whether the session attribute isUser exists (i.e. != null) or not. Then, in
my JSP page, I wrote something like the following:

<isNotUserAuthenticated>
  ....forward her to the login page
</isNotUserAuthenticated>

<isUserAuthenticated>
  <a href="..."></a>
  <a href="..."></a>
  <a href="..."></a>
</isUserAuthenticated>

I discovered this method is also useful to allow 'Administration'
functionality, so that similarly you may declared <isAdministrator>
<isNotAdministrator>

Hope this will help,

Marco
