Re: Refreshing Issue.
Hi Anurag,
Sounds like that when you reset the parameters are being resent, so the
action 'add' action is being called again.
Struts has a way of dealing with this situation with a token stored in
the submit form, here is a link to an earlier thread:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg68432.html
Apparently there is an example of its use in struts-example.war

Hi All,
I am facing a problem in jsp page refreshing. After submitting the page to
add a new record in the database, I again display the same page with the
added record in the list. Now If I press F5 (I am not clicking the ADD
button) it again adds a new record(duplicate record) in the database, which
it should not do.
I have added the following line in my Action Class
response.setHeader("pragma","no-cache");
I have also added the following statement in the struts-config.xml
But still it is adding the duplicate record in the database when i press F5.
Any solution how to overcome this problem..
Thanks and Regards,
Anurag Garg

Hi,
This is a common problem and have a look at the 'Synchronizer Token'
J2EE pattern for more details. Below I am pasting the URL where the
problem is elucidiated.

Re: Refreshing Issue.
opps.. you may loss what it is your displaying if your putting it in
the request..
in which case
..this is the action that lists all your records...
//your forward then recalls the original action
// in your action
return (mapping.findForward("good");
would be one way of doing what you want

RE: Refreshing Issue.
Dear Anurag,
This is a general problem. Actually when you refresh your page
then the previous action which has called this page(which is in this
case this page it self) is again submitted. And this previous page is
taken from the history of your computer. To prevent this you can do one
thing the clear history on submit of this page or else disable the
refresh option.
Cheers
Ravi
