Accessing multidimensional Array using JSTL

Question

Hi there,
first of all: I'm a newbie to JSP/JSTL :-)
I'm calling a Java-bean from my JSP. In this bean, a 2-dimensional array is created which holds four values per entry. I can access this array from my JSP w/ following code:
<jsp:useBean id="feedback" scope="session" class="de.qv.feedback.Feedback"/>
<% feedback.getDaten()     %>
<c:forEach var="ids" items="${feedback.bogenListe}">
     <c:forEach var="ids2" items="${ids}">
          <c:out value="${ids2}" />
          </c:forEach>
</c:forEach>
Now I want the data to be displayed within a HTML-table. How do I do this? I think I have to access each value one by one, but I don't know how.
Any hint will be greatly appreciated!
TIA,
Buzzy

Answer 1

Aye, this works :-)
One more thing: This line accesses each element one by
one:
<c:forEach var="value" items="${docs}">
Is it possible to access a specific value, e.g. only
the 2nd or 4th element?
Or do I have to use a counter and <c:if...> to to
this?No, you can do use the square brackets to get specific values if you want:
<table>
<c:forEach var="docs" items="${feedback.bogenListe}">
<tr>
//Remember arrays are zero indexed so [0][1][2][3][4] second doc = [1]
<td><c:out value="${docs[1]}"/></td><c:out value="${docs[3]}"/></td>
</tr>
</c:forEach>
</table>
//or, if you want all even values, but don't want to manually read them
<c:forEach var="docs" items="${feedback.bogenListe}">
<tr>
<c:forEach var="curr" items="${docs}" begin="1" step="2">
<td><c:out value="${curr}"/></td>
</c:forEach>
</tr>
</c:forEach>
</table>
<td><c:out value="${docs[2]}"/></td><c:out value="${docs[4]}"/></td>
</td>
</c:forEach>
