Hi, thank you for your attention to my problem. First
all, I think that I am missing someting. In order to
use the <c:set ....> and <c:out ... > tags, I think
that I have to import a taglib into my JSP and assign
it with a prefix "c". Which taglib should I import?
Right now, I have these:
<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>
<%@ taglib uri="/tags/tiles" prefix="tiles" %>
<%@ taglib uri="/tags/request" prefix="req" %>
Second,
<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>
<%-- The statement below has no problem to write on
the value --%>
<bean:write name="articleForm" property="creator"/>
Third, the mapping to the next JSP is:
<action
roles="administrator,editor,contributor"
path="/list/Message"
forward=".message.Form"
name="postForm"
scope="session"
validate="false"/>
Fourth, in the postForm.jsp, I try to retrieve the
value of the String that is passed in a session object
and print it out in a text field:
<bean:define id="author" name="cr" scope="session"
type="java.lang.String"/>
<html:text property="creator" value="<%=author%>"
size="82" maxlength="25" tabindex="1"/>
Fifth, the error message is that "cr" cannot be found
in the session scope.
