option2:The code is described as the following.I don't build it . XD

String alf_ticket = getAlfTicket("admin", "admin");
                JSONObject site = new JSONObject();
                site.put("sitePreset", "site-dashboard");
                site.put("shortName", shortName);
                site.put("title", "myTitle"+shortName.substring(0,4));
                site.put("description", "myDescription");
                site.put("visibility", ScriptSiteService.PUBLIC_SITE);               
                site.put("ticket", alf_ticket);
                //client.getParams().setAuthenticationPreemptive(true);
                client.getState().setCredentials(new AuthScope("localhost", 8080), new UsernamePasswordCredentials("admin", "admin"));
               
                //post = new PostMethod("http://localhost:8080/share/service/modules/create-site?alf_ticket="+alf_ticket);
