I have two servers jboss and ejabbered and i have deployed two html files, one on each as follows:

testdirver.html deployed on ejabbered
<html><head>
<script>
function viewmembers()
{var w=window.open("http://192.168.56.134:8080/nkms1/kms/test.html");}
</script>
</head>
<body><form name="sub" >
<input type="text" id="to" name="to">
<button onClick= "viewmembers();">
</form></body></html>

test.html on jboss
<html>
<script>
function abc()
{alert(window.opener.document.forms[0].to);}
</script>
<body onload=abc();></body></html>

Problem: window.opener.document gives the js error "Access is Denied" which i am not able to understand.

Exchanging the two files on the servers(i.e. testdriver.html on jboss and test.html on ejabbered works fine and i get the output [object]). So i am guessing there is something that has to do with the ejabbered server
