CASSINI源代码分析(2)[5]

                _server = new cassini.server(portnumber, _virtroot, _apppath);

                _server.start();

}

//我们可以知道在此，我们先生new一个cassini.server然后调用start过程。出错了就报告错误。源代码中并没有catch(exception e)的语句，是我为了察看错误提示信息加上去的。通过这样做，我知道编译后的程序如何执行。

            catch (exception e){

                            messagebox.show(e.tostring()); 

                showerror(

                    "cassini managed web server failed to start listening on port " + portnumber + ".\r\n" +

                    "possible conflict with another web server on the same port.");

                porttextbox.selectall();

                porttextbox.focus();

                return;

            }

            startbutton.enabled = false;
