> Components: XML Configuration

>
> 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>
