   public string callrestwebservice(){          string result="";        system.out.println(".....rest..........");           httpclient httpclient = new defaulthttpclient();             httpget request = new httpget(wsurl);             responsehandler<string> handler = new basicresponsehandler();             try {                 result = httpclient.execute(request, handler);                system.out.println("..result..."+result);           } catch (clientprotocolexception e) {                 e.printstacktrace();             } catch (ioexception e) {                 e.printstacktrace();             }             httpclient.getconnectionmanager().shutdown();             return(result);       } // end callwebservice()
