catch (DuplicateObjectException e){System.err.println("Duplicate object exception");e.printStackTrace();throw new ServletException("Duplicate object exception");}}The login() method in turn calls the doLogin() method. The doLogin() methodattempts to log the servlet in as a server application. The default connectionmethod is configured to connect through the Sametime mux, so we change thisto connect directly to the server. We do this by explicitly setting the port numberwe wish to connect to (1516), and then calling the setConnectivity() method ofthe ServerAppService object. We specify our login type as LT_SERVER_APP fora server application, then add ourselves as a LoginListener before finally callingthe loginAsServerApp() method. We then wait until we are logged in or until ourlogin attempt times out.
