Struts2 accessing enum from JSP

Question

I have the following class

package com.test;

public class SomeClass {
   public enum COLOR {RED,BLUE}
}

I want to access values of COLOR enum in my JSP. I've tried the following code but it doesn't work.

<s:property value="@com.test.SomeClass.COLOR@RED"/>
<s:property value="@com.test.SomeClass@COLOR.RED"/>

Any body came across this issue before? [I've already enabled static method access in struts.xml]

you can do that but you need to enable `struts.ognl.allowStaticMethodAccess=true` — Umesh Awasthi, Apr 17 '13 at 15:37
have a look at http://stackoverflow.com/questions/6708594/struts-2-iterate-enum — Umesh Awasthi, Apr 17 '13 at 15:40
This question and that one should be merged. The title of this question is clearer but effectively they require the same solution. — Quaternion, Apr 17 '13 at 15:52
@UmeshAwasthi i've already enabled that.But can't seem to be able to access the enum — Dev Blanked, Apr 17 '13 at 16:10
@UmeshAwasthi thanks for the link. I see that trick is to use '$' mark to refer nested classes. — Dev Blanked, Apr 17 '13 at 17:56

For enum-s there is not need to enable static method access.

Enum-s can be accessed using @ sign like that:

<s:property value="@package.ENUM@enumvalue"/>

In your case since you are declaring enum inside class use $ sign to refer to your enum.

<s:property value="@com.test.SomeClass$COLOR@RED"/>

I wish I'd have come across this answer weeks ago. The `$` is what I was missing since my `enum`s are declared inside other classes. – Matt Sep 29 '16 at 12:58
