RE: How To Output the Value of a String That Is Passed From Another JSP?
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:x .../ actions will work.

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:submitView/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?

To make sure it is actually putting the value in

If so, then on postForm.jsp try using scriplets to

the value can be accessed. If it can, then do you
have all of your

There are two JSPs; view.jsp and postForm.jsp and
each

In my view.jsp, I am able to write out String
creator

RE: How To Output the Value of a String That Is Passed From Another JSP?
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 %
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:submitView/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.

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:submitView/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}/

request.getSession().setAttribute(creator, creator);
return mapping.findForward(success);
In JSP#2 you could do something like this:
c:out value=${creator}/

populate the form used

RE: How To Output the Value of a String That Is Passed From Another JSP?
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:submitView/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?

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:submitView/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'

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?

RE: How To Output the Value of a String That Is Passed From Another JSP?
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:submitView/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?
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:submitView/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.

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:submitView/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}/
