findforward w/session objects
Hello
When I use the code below the Action "playThis" claims
the file attribute is null. It is not unless I am
loosing the session on the findforward. How can I
store a value in the session and forward to an Action?
The first line of the "playThis action is String file
= (String) request.getAttribute("file"); so why is
attribute null? Any enlightment welcomed.
System.out.println("file= "+temp);
session.setAttribute("file", temp);
return actionMapping.findForward("playThis");

Posted by Leon Rosenberg <ro...@googlemail.com>.
session.setAttribute("file", temp);
vs.
request.getAttribute("file");
you know that request and session are different scopes?
change the second line to request.getSession().getAttribute("file");

Hi Geeta
Thank you. Even though it is a major point, I am
getting killed by syntatic problems. I know the
sophisticated issues but the "blocking & tackling" is
my present downfall. I feel like I am the teacher and
student in the Jaime Escalante story, grin.

What error are you getting? That String file below is null? Maybe the
error is differnet from what you think it is..?
If not, this is strange. I have set countless session vars and forwarded
to different actions and got the variables back fine, so try the following
things:
1. Clean out your work directory, do a full rebuild, restart tomcat and
try again.
2. Check and make sure you are forwarding to something which is still in
the same web context. (recheck the struts-config.xml).

Hi Geeta, et. al
I typed too soon. I am still getting a servlet error
even with this modified code and not getting a the
println produced.
playThis action:
HttpSession session = request.getSession(false);
if (session == null)
System.out.println("null session");
String file =
(String)session.getAttribute("file");
I confirmed that the file object was in the session
before the actionMapping.findForward("playThis") and
with the getSession(false) I am not creating the
session and should be only retrieving the session I
confirmed existed and was populated before the
findForward. What am I obscenely not recognizing
here? Many thanks for any enlightenment.

Chris, here's your problem: You are storing temp as a session attribute,
but retrieving it as a request sttribute. So replace (String)
request.getAttribute("file") with (String) session.getAttribute("file"),
and you should be ok..
