authentication in tomcat

[Clara Hall]

Hi,
I developed a web application which only allow authorized user to use it. There are two kinds of users, the general user is allowed to view the material, the power user can do some edit. The view operation and edit operation are handled by different servlets. So I want to set some servlets can be run by both general users and power users, while some servlets can only be invoked by power users. Is there anybody has any idea? Thanks.

Here is a good article describing authentication in Tomcat. It should get you started in the right direction.
