Thanks for your advice. I did this in my view.jsp:
<html:form action="/list/Message">
<c:set var="cr" value="${articleForm.creator}"
scope="session"/>
<c:out value="${cr}"/>
<html:submit>View/Send Messages</html:submit>
</html:form>
<bean:write name="articleForm" property="creator"/>
I was able to see the "View/Send Messages" button
displayed. And the <bean:write name="articleForm"
property="creator"/> also wrote out the value of the
property "creator".
Now, the question is
1. why the <c:set var="cr"
value="${articleForm.creator}" scope="session"/> did
not put the value in the session scope?
2. What is wrong with the <c:set .... > tag?
3. What should I do if I want to put the value of
"creator" in a session scope?
