How to use
If a page url inclues a parameterName, then you can see the value on the page.
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title>Tag Example</title>
</head>
<body>
<c:out value="${param.parameterName}"/>
</body>
If value is null, the default value takes over. If no default value is specified, it itself defaults to an empty string.
