When a URL comes along, such as: Http://localhost:8080/pro/demo/hello.jsp?name=john, on the hello.jsp page, we can get the value of name: The code is as follows: <% String  Path = Request.getcontextpath ();  String basepath = request.getscheme () + "://" +request.getservername () + ":" +request.getserverport () +path+ "/";    String name = Request.getparameter ("name");///%> and then displayed in <body>hello:<%=name%></body>. It can also be obtained directly in the body with ${}, because the URL request parameter is placed in the implied object param when the jstl is used.
