java - How to display the same code, when you are logged in on different pages in jsp? -


everyone.

i start learning spring+bootstrap , create web app, have admin cp section... created login functions, , display content when have logged in , warning message when not logged in.

so problem use of tags.

i have following structure of code.

    <c:choose>     <c:when test="${mode == 'admincp' }">     <c:choose>     <c:when test="${loggedin eq true }">     <!-- start navbar code -->            </c:when> <c:otherwise> <!-- start code diplay warning message when not logged in --> </c:otherwise> </choose>  </c:when> </choose>

i used first c:when tag () , because if don't when i'm not logged in warning message shop everywhere in pages don't need logged in see them.

and question is. how can add different c:when tags inside on 1 

 <c:choose>         <c:when test="${loggedin eq true }">

after navbar code, represent different pages.

the final structure this.

  <c:choose>         <c:when test="${mode == 'admincp' }">         <c:choose>         <c:when test="${loggedin eq true }">         <!-- start navbar code -->       <c:choose>         <c:when test="${mode == 'another page' }">          </c:when>  <c:when test="${mode == 'another page' }">          </c:when> </choose>        </c:when>     <c:otherwise>     <!-- start code diplay warning message when not logged in -->     </c:otherwise>     </choose>      </c:when> </choose>

and on end have in admin cp pages nav bar, , content displayed if user logged in.

p.s try code , reason not working.

thanks, in advance.
