passing values from child window to parent window
<p>Hi this is my first question in this site.</p>

<p>My problem is-I have created a jsp where in i have given one link to call another jsp (already created by some one) in a popup window.On saving some details in child window i want those values to be accessed in my parent window.But i dont have the permission to change the code of child window jsp. 
can anyone help me...?
Thanks,
the code i am using to open a popup is as follows.</p>

<pre><code>function popUp(url){
    alert("inside popup");
    window.open(url,'newWindow','width=750,height=400,left=150,top=100,toolbar=no,resizable=true');
}
</code></pre>
