You are missing this one: <%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %> > > 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"/> That's because you were missing the JSTL taglib directive above. > > 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"/> > Why are you defining an action path at all. Once you add the JSTL taglib directive the following line places the value in the session. There is no need to submit. <c:set var="cr" value="${articleForm.creator}" scope="session"/> > Fourth, in the postForm.jsp, I try to retrieve the > value of the String that is passed in a session object > and print it out in a text field: > > <bean:define id="author" name="cr" scope="session" > type="java.lang.String"/> > <html:text property="creator" value="<%=author%>" > size="82" maxlength="25" tabindex="1"/> > You could use Struts-EL and do something like: <html_el:text property="creator" value="${cr}"/> The Struts-EL taglib and jar file can be found in the /contrib directory of the Struts distribution. > Fifth, the error message is that "cr" cannot be found > in the session scope. > Once again, this is because the JSTL taglib directive is missing. > -Caroline > > --- Robert Taylor <[EMAIL PROTECTED]> wrote: > > What exactly are you trying to accomplish?
