Description

It would be nice to be able to reference Struts constant declaration values from within the configuration files.

For example, if you wanted to set a common value for "max file upload size", you could define a constant and reference it in multiple locations from within struts.xml (or any included xml configuration file)

[struts.xml]
<struts>

   <!-- Custom Constant Declarations -->
   <constant name="my.constant.maxFileSize" value="20971520"/>     <!-- Max size for individual files (20 MB) -->

   <package>

       <action name="ActionName" class="com.my.action.class.ActionName">
           <interceptor-ref name="myFileUploadStack">
               <!-- REFERENCE CONSTANT HERE -->
               <param name="fileUpload.maximumSize">${my.constant.maxFileSize}</param>
           </interceptor-ref>
       </action>

    </package>
</struts>
