Question

Is there a way to use Enum values inside a JSP without using scriptlets.

e.g.

package com.example;  public enum Direction {     ASC,     DESC } 

so in the JSP I want to do something like this

<c:if test='${foo.direction ==<% com.example.Direction.ASC %>}'>... 

Answer 1

You could implement the web-friendly text for a direction within the enum as a field:

  <%@ page import='com.example.Direction' %> ... <p>Direction is <%=foo.direction.getFriendlyName()%></p> <% if (foo.direction == Direction.ASC) { %> <p>That means you're going to heaven!</p> <% } %>  

but that mixes the view and the model, although for simple uses it can be view-independent (‘Ascending’, ‘Descending’, etc).

Unless you don’t like putting straight Java into your JSP pages, even when used for basic things like comparisons.
