Rewriting EL expressions in a loop

In my jsp page some data is read from the request object and displayed:

Code:

---

Dataset 1:
<br></br>
${requestScope.DataObj.person[0].name}
<br></br>
${requestScope.DataObj.person[0].age}
<br></br>
<img src="${requestScope.DataObj.person[0].image}" />
<br></br>

Dataset 2:
<br></br>
${requestScope.DataObj.person[1].name}
<br></br>
${requestScope.DataObj.person[1].age}
<br></br>
<img src="${requestScope.DataObj.person[1].image}" />
<br></br>

Is it possible to use a loop here?

Look at the standard tag library, specifically the forEach tag.
That'll iterate over your collection.

The problem are the details. I tried it this way, but it doesn't work:

Code:

---

<c:forEach var="x" items="${requestScope.DataObj.person}"> 
<c:out value="${x.name}" />
<br></br>
</c:forEach>

---

When I call this, I don't get any output:

Code:

---

<c:choose>
        <c:when test="${requestScope.DataObj.person}">
                <c:out value="data available: yes"></c:out>
        </c:when>
        <c:otherwise>
                <c:out value="data available: no"></c:out>
        </c:otherwise>
</c:choose>

hey ,
did you copy the standard tag Jar to your project?
and <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> in your page?

What does "it doesn't work" mean?
