public static field of a public inner class cant be accessed as @FQClassName@Field in struts 2

[Saikat Podder]

I found in the OGNL Language reference that the a static field of a class has to be referenced using the syntax @FQClassName@field where FQClassName is the fully qualified name of the target class. It is working for any normal class. But I failed to access the fields of an inner class using the same syntax.

package myapp.test;

public class Constants
{
   //fields & methods here.....
   public class Plan
  {
      public static final String FREE = "free";
      //other things..
  }
}

Trying to access it as

<s:property value="@myapp.test.Constants.Plan@FREE" />

Is not working!! I also have tried it after making Plan as public static, still dosnt work

so my question is, is there any way (at all) to access the static field of the inner class?

Thanks in advance
