这是我FORM提交的表单，我在另一个页面接的，
SmartUpload su = new SmartUpload();
String gname = su.getRequest().getParameter("txtgname");
String gprice = su.getRequest().getParameter("txtgprice");
String im = su.getRequest().getParameter("myfile");
String gil = su.getRequest().getParameter("txtgil");
System.out.println(gname);
System.out.println(gprice);
System.out.println(im);
System.out.println(gil);
结果为什么我打印的都是NULL啊，
