Problema com o out jstl

Front-end
#1

Estou iniciando com a linguagem JSP, e estou tendo problema com a manipulação de uma variável que é criada com a biblioteca JSTL (no trecho : "<c:set var= “test” value= “Session Level Value” scope= “page” /> ") e logo após ao tentar imprimir esta variável (<c:out value= “${test}” /> ) é gerada a exception
Segue código abaixo:

[code]<%@ taglib uri=“http://java.sun.com/jsp/jstl/core” prefix=“c” %>

<% //String variavelteste = “conteudo”; %>

    <!--[if IE]>
        <link rel="stylesheet" type="text/css" href="iehacks.css" />
    <![endif]-->
    
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
</head>
<body>        
    
    <div id="topo">
        <div id="logo_brasil"></div> 
        
    </div>
    
    <div id="all">

           <c:set var= "test" value= "Session Level Value" scope= "page" /> 
        
            <c:out value= "${test}" /> 


        
        <div id="menu">
            <c:import url="menu.jsp"/>
        </div>                 
        
        <div id="conteudo_interno">
            
            <c:import url="incluirveiculo.jsp" />    
        </div>
    </div>
    
    <div id="rodape"></div>
    
</body>
