pop up window to display an array object using Tomcat

Hi,
My problem looks like a javascript problem, but
it is more seen when using Tomcat as the web server.
I have a file (test.jsp) listing a list of items. When I click any of them, a popup window
will display the corresponding data. The data are stored in two arrays (array1 and array2).
But when I switch between the links, sometimes, the popup window does display the
corresponding data, but sometimes displays nothing, Any clues?
If I change the code to remove blank.htm page (example: window.open('','TheRemote'....) ),
the output is appended to the end of the string.
Thanks for help!

test.jsp:
<html>
<head><title>JSP Page</title>
<script language="JavaScript" type="text/JavaScript">
var array1 = new Array( );
array1[0] = "Item1a";
array1[1] = "Item1b";
var array2 = new Array ();
array2[0] = "Item2a";
array2[1] = "Item2b";
function displayArray (x) {
var remote = window.open('blank.htm','TheRemote',"height=250,width=250,status=yes,toolbar=no,menubar=yes,location=no,resizable=yes,scrollbars=yes");
remote.focus();
var output = "";
for (var i=0; i<x.length; i++) {
output += x[i] + ';';
}
output = "<html><head><title>test</title></head><body>" + output + "</body></html>";
remote.document.write(output);
}
</script>
</head>
<body>

<A HREF="javascript

isplayArray(array1);" >Item One</a><BR>
<A HREF="javascript

isplayArray(array2);">Item Two</a><BR>
</body>
</html>

blank.htm (located in the same directory as test.htm)
