when i am trying to run the jsp page on server getting

HTTP Status 403 - Access to the requested resource has been denied

how can i associate the role with the request .do i need to do any extra configuration ?Please help.

what kind of auth-method you are using ? and where do you put your authentication detail; for instance if you use tomcat then user details will be in tomcat-users.xml

I am using Basic authentication for tomcat and added the role in tomcat-user.xml
