HI,

Here's my dilemma. The below code is obviously wrong but it give you the idea on what I need to accomplish.

<c:forEach var="object1" items="${model.listofObjects1}">
  <tr>
    <c:forEach var="object2" items="${model.listofObjects2}">
      <td>${object1.${object2}}</td>
    </c:forEach>
  </tr>
</c:forEach>

Any ideas on how to make this look up?

回答1:

Use the brace notation.

<td>${object1[object2]}</td>
