Hi Poonam,
Yes I am able to open URL independently in the browser.
I am using not using any class to generate url, I am concatenating few values to create url and in the .htm, I am trying to open the url in a seperate window as given below:
<script type="text/javascript" language="javascript">
window.open("<%=controller->zv_url%>").focus();
</script>
