Hi
For saving some data entered in initial.jsp I call save.jsp which does the necessary save and returns to the initial page through a forward to initial.jsp.
However the url still stays at save.jsp and a click on refresh button of browser resends the info and creates duplicate records in DB.
I dont want to use send redirect and I dont want to use javascript to disable refresh button.
I wqant the url to reflect initial.jsp after the save so that refresh does nothing....
can somebody help me out.....
thanx,
fred.

I suggest you put something in session -- a boolean flag maybe? that's set to true once the record is entered, so that if they DO hit reload -- you first look for the flag, and if you find it -- you don't enter the thing in the DB.
'cause the thing is -- when you use .forward() the request happens within the app server -- so the URL displayed in the browser will not change. The only way to change it is to use the .sendRedirect() method... which you already said you don't want to do.

"fred flintstone",
Fictitious names are not allowed, sorry.
Please check out the naming convention at http://www.javaranch.com/name.jsp.
Please edit your profile and select a new name which meets the requirements.
I noticed you've changed your display name from a valid one to an invalid one. You should change it back quickly, since accounts with invalid names get deleted.
Thanks.
Dave

say, you saved the record in db with the method saveRecord().
<%
boolean isOK=saveRecord();
if(isOK){
%>
<html>
<header>
<META HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.some.org/some.html">
</header>
</html>
<%
}else{
...
}
%>
----------------
is that ok?
