I'm starting my studies in jsp and I came across the following situation: I want to use the forEach of jstl c: foreach and want to use a list that is returned by my DAO method.

<body>
<jsp:useBean id="dao" class="teste.ContatoDAO"/>
<table>
    <tr>
        <th>Nome</th>
        <th>Email</th>
        <th>Endereco</th>
    </tr>
     <c:forEach var="contato" items="${dao.findAllContatos}">
        <tr>
            <td>${contato.nome}</td>
            <td>${contato.endereco}</td>
            <td>${contato.email}</td>
        </tr>
    </c:forEach>
</table>

Where this $ {dao.findAllContacts} is my DAO method that returns a list of contact objects. However, jsp thinks that findAllContacts is a property when in fact it is a method. How do you get around this problem? Thank you in advance.

Hello! As suggested by Andrew, use dao.findAllContacts ().

Expression language only takes getter methods without the need to use parentheses. In other methods, its use becomes necessary.

Look for the Java-to-Web handout made available in PDF by Caelum. There, you will find a more detailed explanation.
