Wendy,

Thanks so much for your response.  Sorry I have replied until now – 
I’ve had my head down trying to get the coding done.  I used the

<c:set var="jstlName">
    <bean:write name="myDynaBean" property="name" />
 </c:set>
 <c:out value="${jstlName}">

trick for the demo version.  I will revisit this this week with a view 
to hopefully using the DynaActionForms technique.

I’m using tomcat 5 by the way.
