Need to open a popup from server side

[Kamalesh Kumar]

Hi ,

I want to call a javascript function to open a popup from server side.
I have a commandLink on which an actionListener  is specified . The code 
is as below:

   ExternalContext eCon = 
FacesContext.getCurrentInstance().getExternalContext();
       HttpServletRequest request = (HttpServletRequest) 
eCon.getRequest();
       selWkshtCol = request.getParameter("selectedWkshtCol");

       FacesContext facesContext = FacesContext.getCurrentInstance();
       String actionUrl = "validation.jsf";
       String javaScriptText = "window.open('"+actionUrl+"', 
'popupWindow', 'dependent=yes, menubar=no, toolbar=no');";

       AddResource addResource = 
AddResourceFactory.getInstance(facesContext);
       addResource.addInlineScriptAtPosition(facesContext, 
AddResource.HEADER_BEGIN, javaScriptText);


This  is not opening the popup.
Please suggest.

Regards
Kamalesh
