Set the role in session and get it in JSP page. In servlet,

session.setAttribute("Role", "administrator");

And in JSP,

<%
 String role= (String)session.getAttribute("Role");
 pageContext.setAttribute("role",role);
%>

Here I assumed that you are using JSTL for standard (Just add this line <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>). 

<c:choose>
    <c:when test="{role == 'administrator'}">
        <!-- Menu Choice 1 -->
    </c:when>
    <c:otherwise>
        <!-- Menu Choice 2 -->
    </c:otherwise>
</c:choose>

See BalusC answer for more details. Hope this helps.
