Collecting data from several jsp
Hello,
I am using struts in my web application. To register a
customer a need several JSPs with different forms. The
data are not stored in the database until the last
form is filled and "Submit" button is clicked. Could
someone recommed me a good design for collecting data
from several JSPs using struts? Probably this is a
basic question, but I am new in web-application
programming and would appreciate any help.
Regards
Olga

Thanks again, Robert
I believe the approach with the session-timeout is
better than having dozens of hidden fields. Having
information in the bean is easier to debug.
Thanks

RE: Collecting data from several jsp

You can set the session time out in web.xml for the web application.
<session-config>
<session-timeout>30</session-timeout>
</session-config>
When the session times out, your bean will gc'd.
If your bean uses any resources, then you may want to wrap it
in a class that implements HttpSessionBindingListener interface.
>From the API:
HttpSessionBindingListener:
Causes an object to be notified when it is bound to or
unbound from a session. The object is notified by an
HttpSessionBindingEvent object. This may be as a result
of a servlet programmer explicitly unbinding an attribute
from a session, due to a session being invalidated, or
die to a session timing out.
Good luck,
robert

Thanks, Robert
I believe the second approach is better for me. I have
to build the site having in mind that there might be a
number customers connected to the site at the same
time and many of them might start registering and
change their mind somewhere in the middle of the
process. So, leaving a number of JaveBeans in the
session is really risky (unless I can set a session
time out and remove the abandoned bean when it is
timed out).
Thanks again

One possible solution is to store information collected from your forms and
store it in a JavaBean in your session. After you persist the information
you could remove the bean from the session.
You do run the risk of the user leaving the process and having data hanging
around.
Another solution is to "store" the collected information in hidden form
fields as the user progresses through the process. This way if they leave
the process, no data is left hanging around.
This has been discussed before; check the mail archives at
