Wendy,
Thanks so much for your response. Sorry I have replied until now
Ive 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.
Im using tomcat 5 by the way.
