Examples with WebRoleRefPermission javax.security.jacc.WebRoleRefPermission used on opensource projects

Example 1 with WebRoleRefPermission

use of javax.security.jacc.WebRoleRefPermission in project javaee7-samples by javaee-samples.

the class SubjectServlet method doGet.

            permissionCollection.implies(new WebRoleRefPermission("", "nothing"));
            // Filter just the roles from all the permissions, which may include things like 
            // java.net.SocketPermission, java.io.FilePermission, and obtain the actual role names.
