I am trying to just set up a very basic jsp file that takes in a query from a url and displays it. I have the following test.jsp file that I run on the server:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Test jsp</title>
</head>
<body>
<% String firstName = (String) request.getAttribute("firstName");
out.println("Hello :" + firstName);%>
</body>
</html>
However, when I type in the following URL, I still get a "null" result (even after refreshing): see Picture.
Note: my ultimate goal is to do have an event at some point that sends a POST request from a java file and display its result in the jsp page. If I understood well from my research, I would have to do it via a Servlet with a DispacherRequest forwarding method. But I first want to understand why the simple aforementioned code isnt working).
Thank you for your help !
