[opencms-dev] Login module

[Jeff Greer]

Here is some JSP code that I use to login. It has a login form built in to it.
I have the file represented in my system as an elements file called login.jsp. Then I have a common template that I
use to define the layout of the site and include the login.jsp where I want it to show up. I use cascading style
sheets to define the look and feel of the form.

Hope this helps.

Cheers.
