Want to populate text box of other sites from my code

Hi,

I have a link on myweb page[mycode] which open another site [Which is not my code].
I want to populate the textbox of second site with some message whenever a user click on link of mysite.

----------------------------------------------
what I tried:
1. Reguest parameter
e.g.
window opan("http://www.anotherDomain.com?firstname="+fName+"&lastName="+lName,"_newWin");}

Resut: Not working

-----------------------------------------------------

2.

script language="javascript"
function openWindow(){
var newWin = window opan("http://www.anotherDomain.com", "newWin");
alart("success");
newWin.document getElementBiId("fName") value=document getElementBiId("txt1") value;

}
/script
/head
body
input type="text" name="txt" id="txt1"/
a href="#" target="_blank" on_Click="javascriptopenWindow(); return false;" Click Me /a
/body
/html

Result: Not working
---------------------------------------------------------------------

3. Using ajax, modify the response and rewrite in new window
Result: message is populating but URL is gone from address bar.
---------------------------------------------------------------

What I want ?
Solution Code! using JAVA,Servlet,JSP,javascript or AJAX

What I don't want?: 'Not possible'

Thanks and Regards,
Happy Java

Welcome to the JavaRanch.

We're a friendly group, but we do require members to have valid display names.

Display names must be two words: your first name, a space, then your last name. Fictitious names are not allowed.

Please edit your profile and correct your display name since accounts with invalid display names get deleted.

JavaScript has a same domain policy. If the webpage is in a different domain, it is not going to work. Only way to populate the data is to have the other site take the querystring parameter and handle it.
