opening multiple windows with Mozilla Embedding

Hi, Am trying to open a  Browser window using Mozilla Interfaces. I
could achieve opening one window. But now I want to open Multiple
windows ( Child windows). tags may also Do.
Below is the code that I used to open a window.
mozilla.initEmbedding(grePath, grePath, locProvider);
			serviceManager = mozilla.getServiceManager();
			appStartup = (nsIAppStartup)
serviceManager.getServiceByContractID(	"@mozilla.org/toolkit/app-
startup;1",nsIAppStartup.NS_IAPPSTARTUP_IID);
			windowCreator = (nsIWindowCreator)
appStartup.queryInterface(nsIWindowCreator.NS_IWINDOWCREATOR_IID);
			windowWatcher = (nsIWindowWatcher)
serviceManager.getServiceByContractID("@mozilla.org/embedcomp/window-
watcher;1",	nsIWindowWatcher.NS_IWINDOWWATCHER_IID);
			windowWatcher.setWindowCreator(windowCreator);

domWindow = windowWatcher.openWindow(null, url,"mywindow",
"resizable,centerscreen", null);
		windowWatcher.setActiveWindow(thinClient_popup_Window);
		nsIDOMWindowInternal winint = (nsIDOMWindowInternal)
thinClient_popup_Window.queryInterface(nsIDOMWindowInternal.NS_IDOMWINDOWINTERNAL_IID);
		winint.setInnerHeight(950);
		winint.setInnerWidth(1260);
		appStartup.run();



at this point the Window opens,  but I am not able to open another
window after this,
Am really stuck how to proceed further.

I am actually running a socket. every request to the socket will
replace the URL in this window.

servSock = (nsIServerSocket)
serviceManager.getServiceByContractID("@mozilla.org/network/server-
socket;1",nsIServerSocket.NS_ISERVERSOCKET_IID);
		transService = (nsISocketTransportService)
serviceManager.getServiceByContractID("@mozilla.org/network/socket-
transport-service;1",
nsISocketTransportService.NS_ISOCKETTRANSPORTSERVICE_IID);
		sockTrans = transService.createTransport(null, 0,"localhost", 7055,
null);
		servSock.init(7055, false, -1);
		listener = new SockListener(servSock, sockTrans,
serviceManager,thinClient_popup_Window);
		servSock.asyncListen(listener);

Now am in need of opening multiple windows....
Any help will be appreciated. Thanks in Advance.
