The template is mapped to the correct action, if that's what you're 
asking.  These things work:
${myValue}  (indirect access to bean getter)
${myValue.toUpperCase()}  (method call on object)
<@s.property value="myMethod()"/>   (Struts tag calling a method)

But these things don't:
${myMethod()}
${getMyValue()}  (plain method calls as described in the docs)
