Adding the following to web.xml will define security constraints for all resources under the /admin directory, also only a user in the manager role will have access to these resources.
For tomcat you can look at the conf/tomcat-users.xml file for setting up users and roles
     <security-constraint>
          <web-resource-collection>
               <web-resource-name>Secure Pages</web-resource-name>
               <description></description>
               <url-pattern>/admin/*</url-pattern>
               <http-method>GET</http-method>
               <http-method>POST</http-method>
          </web-resource-collection>
          <auth-constraint>
               <description></description>
               <role-name>manager</role-name>
          </auth-constraint>
     </security-constraint>
     <security-role>
          <description></description>
          <role-name>manager</role-name>
     </security-role>
