Aceder por JSP a um Session Bean em JBoss

Programação Java
#1

Eu tenho estado a tentar criar um exemplo no JBOSS, em que se tem um session bean e é acedido por JSP.

test.jsp

<%@ page import="javax.naming.InitialContext,
                 javax.naming.Context,
                 java.util.Properties,
                 com.zoo.Tiger,
                 com.zoo.TigerBean"%>
<%
    Properties props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY,
            "org.jnp.interfaces.NamingContextFactory");
        props.put(Context.PROVIDER_URL, "localhost:8080");

    Context ctx = new InitialContext(props);
    TigerBean home = (TigerBean)ctx.lookup("Tiger");
    String str = home.roar();
    ctx.close();
%>

<html>
<head>
<title>Insert title here</title>
</head>
<body>
<b><%= str %></b>
</body>
</html>

Quando uso o link:
http://localhost:8080/ZooClient/test.jsp

tenho o erro:
