javax.el.PropertyNotFoundException: Свойство 'foo' не найдено в типе com.example.Bean

У меня есть результаты из

Query query = session.createQuery("From Pool as p left join fetch p.poolQuestion as s");

запроса, и я хотел бы отобразить их в JSP.

У меня есть цикл:

<c:forEach items="${pools}" var="pool"> 

    <p>${pool.name}</p>

</c:forEach>

, и я хотел бы вывести результаты из таблицы poolQuestion (которая является таблицей соединения). Значение, которое я хочу отобразить, - «ответ».

Как я могу это сделать?

<c:forEach items="${pools}" var="pool"> 
    <p>${pool.answer}</p>
    <p>${pool.name}</p>             
</c:forEach>

Приведенный выше код не работает.

Ошибка:

  org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/views/home.jsp at line 21

Модель:

public List<Pool> getAll(){

    Session session = sessionFactory.getCurrentSession();

    Query query = session.createQuery("From Pool as p left join fetch p.poolQuestions as s");

    return query.list();

Контроллер:

List<Pool> pool = poolService.getAll();

model.addAttribute("pools", pool);

И вид:

<c:forEach items="${pools}" var="pool"> 

    <p>${pool.name}</p>
    <c:out value="${pool.answer}"/>

</c:forEach>

PS. $ {pool.name} отображается правильно
