If you are not logged in a login procedure is put in by Resin before you get to the pages. If you are logged in, you may be able to see them or you may get a 'Forbidden' error. <p> Links to different areas: <ul> <li><a href="<c:url value='students/'/>"> Students (available to 'students' and 'professors') </a> <li><a href="<c:url value='professors/'/>"> Professors (available to 'professors') </a> <li><a href="<c:url value='staff/'/>"> Staff (available to 'staff' and 'professors') </a> </ul> In a real application, you wouldn't show links like this -- you would get the user to login first and then only display the links that are available for their role. <%@ include file="/inc/footer.jspf" %> </body></html>⌨️ 快捷键说明
