RE: How To Output the Value of a String That Is Passed From Another JSP?
Hi, my JSP#1 and JSP#2 use different forms. However,
property name in JSP#1 is the same as that in JSP#2.
I tried to pass this Sring and write it out in a text
field in JSP#2 and just could not get it right. I got
this error
message:
[ServletException in:/article/content/postForm.jsp]
Cannot find bean cr in scope session'
In my view.jsp, I put a String in a session object:
<html:form action="/list/Message">
<c:set var="cr" value="${articleForm.creator}"
scope="session"/>
<html:submit>View/Send Messages</html:submit>
</html:form>
And in postForm.jsp, I tried to retrieve that String
and write it out in a text field this way:
<bean:define id="author" name="cr"
scope="session" type="java.lang.String"/>
<html:text property="creator"
value="<%=author%>" size="82" maxlength="25"
tabindex="1"/>

Thank you for your time and support. It is the JSTL
taglib directive I missed in my page. Now, everything
works as expected.

I bet your missing the JSTL taglib directive in your page.
Try adding
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
and then your <c:xxxxx .../> actions will work.

RE: How To Output the Value of a String That Is Passed From Another JSP?
Posted by Caroline Jen <ji...@yahoo.com>.
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?

RE: How To Output the Value of a String That Is Passed From Another JSP?
Posted by Robert Taylor <rt...@mulework.com>.
Are you sure that <c:set var="cr" value="${articleForm.creator}"
scope="session"/>
is placing the value in the intended scope?
Try doing this:
<html:form action="/list/Message">
<c:set var="cr" value="${articleForm.creator}"scope="session"/>
<c:out value="${cr}"/>
<html:submit>View/Send Messages</html:submit>
</html:form>
To make sure it is actually putting the value in session scope.
If so, then on postForm.jsp try using scriplets to make sure that
the value can be accessed. If it can, then do you have all of your
tag library directives in your pages?

RE: How To Output the Value of a String That Is Passed From Another JSP?
Posted by Caroline Jen <ji...@yahoo.com>.
"cr" is not a form and there is no action involved.
There are two JSPs; view.jsp and postForm.jsp and each
is with its own form (different forms).
In my view.jsp, I am able to write out String creator
this way:
<bean:write name="articleForm" property="creator"/>
and I put the String creator in a session object:
<html:form action="/list/Message">
<c:set var="cr" value="${articleForm.creator}"
scope="session"/>
<html:submit>View/Send Messages</html:submit>
</html:form>
and in the postForm.jsp, I retrieve the String and try
to write 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"/>
I got this error message:
ServletException in:/article/content/postForm.jsp]
> Cannot find bean cr in scope session'

RE: How To Output the Value of a String That Is Passed From Another JSP?
Posted by David Friedman <hu...@ix.netcom.com>.
Caroline,
How do you save the form "cr" in session scope?
Does your action use 'scope="session"' or are you
doing a 'request.getSession().setAttribute("cr",cr);'
in the first action?

David

Hi, my JSP#1 and JSP#2 use different forms. However,
property name in JSP#1 is the same as that in JSP#2.
I tried to pass this Sring and write it out in a text
field in JSP#2 and just could not get it right. I got
this error
message:
[ServletException in:/article/content/postForm.jsp]
Cannot find bean cr in scope session'
In my view.jsp, I put a String in a session object:
<html:form action="/list/Message">
<c:set var="cr" value="${articleForm.creator}"
scope="session"/>
<html:submit>View/Send Messages</html:submit>
</html:form>
And in postForm.jsp, I tried to retrieve that String
and write it out in a text field this way:
<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 are missing this one:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

That's because you were missing the JSTL taglib directive
above.

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"/>

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.

Once again, this is because the JSTL taglib directive is missing.

RE: How To Output the Value of a String That Is Passed From Another JSP?
Posted by Caroline Jen <ji...@yahoo.com>.
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.

RE: How To Output the Value of a String That Is Passed From Another JSP?
Posted by Robert Taylor <rt...@mulework.com>.
What exactly are you trying to accomplish? What's the
high level view?
If you can explain your intent, maybe we can suggest an easier
way to accomplish your goal.
Is articleForm associated with action mapping "/list/Message"?
If so, then you could do something like:
<html:form action="/list/Message">
<html:hidden property="creator"/>
<html:submit>View/Send Messages</html:submit>
</html:form>
This of course, assumes you have already populated creator in
articleForm in some other action using the same form.
The action with mapping "/list/Message", which processes articleForm could
do something like:
MyForm articleForm = (MyForm) form;
String creator = articleForm.getCreator();
request.getSession().setAttribute("creator", creator);
return mapping.findForward("success");
In JSP#2 you could do something like this:
<c:out value="${creator}"/>
