Hi yzme,
You put the url that you want to open.URL should be valid.
     String linkToBeOpen = "https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59";
     IWDWindow window =
     wdComponentAPI.getWindowManager().createNonModalExternalWindow(
                         linkToBeOpen,
                         "My window title");
     window.show();
Regards,
Mithu
