[OT(?)] Comparing against a typesafe enum in JSTL

[Janne Mattila]

First, apologies for a slightly OT question; this is more about JSTL and 
less about Struts.

Let's say I have a "Role" object in session. It is a typesafe enum, with 
values Role.ADMIN and Role.USER. How can I compare the object in session 
against those values, using JSTL? I can't figure out how to refer to 
typesafe enum objects using the JSTL notation. And I don't really want to 
change the enum class into a JavaBean.

Role:
public class Role {
        private char roleChar;
        public static final Role USER = new Role('u');
        public static final Role ADMIN = new Role('a');
        private Role(char roleChar) {
                this.roleChar = roleChar;
        }
        char getRoleChar() {
                return roleChar;
        }
        public boolean equals(Object obj) {
                Role r2 = (Role) obj;
                if (r2 == null) {
                        return false;
                }
                return r2.getRoleChar() == roleChar;
        }
}
My attempt to use it in JSP page:
<c:choose>
<c:when test="${sessionScope.role == cd.business.Role.ADMIN}">
 Hello Admin
</c:when>
<c:otherwise>
 Hello User
</c:otherwise>
</c:choose>
does not work.
(this special case could possibly be handled using container managed 
authorization and it's roles etc....but it's not really the point here)
