Hi, NFuse provides several jsp (or asp) pages to make a portal. In one this page (launch.jsp or launch.asp) it's possible to use the method getLastError() of the TemplateParser object (in fact this method is inherited from the WebPNObject object). The CSS problem comes from the getLastError() method. It does not filter the URL parameters that cause the problem. Exemple : if your launch.jsp contains a bit of code like this : if (!parser.Parse()) { out.println("Error: " + parser.getLastError()); } else { ... } With a request like this you can get the cookie with login and password (the user must be connected before) : http://my_nfuse_portal.com/launch.jsp?NFuse_Application=
