如何在Liferay7中将ArrayList集从java传递给jsp

ArrayList<String> myList = new ArrayList<>();
myList.add("Item 1");
myList.add("Item 2");
myList.add("Item 3");

request.setAttribute("myList", myList);

<ul>
  <c:forEach var="item" items="${myList}">
    <li>${item}</li>
  </c:forEach>
</ul>

<ul>
  <c:forEach var="item" items="<%= request.getAttribute("myList") %>">
    <li><c:out value="${item}" /></li>
  </c:forEach>
</ul>
