Rewriting EL expressions in a loop

[noodle_variation_187-X]

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

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:

<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:

<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?
