Logic:Iterate Problem
Hi guys,
Say I have a JSP as follows:
<table>
<tr>
<%
Iterator iter = pageRecords.iterator();
while(iter.hasNext())
{
UserDetail detail = (UserDetail)iter.next();
%>
<td> <%= detail.getId() %> </td>
<%
}
%>
</tr>
</table>
pageRecords is a Collection of UserDetail object.
UserDetail is my data transfer object.
I can manage to get the expected result of detail.getId()
How can I represent the above code in <logic:iterate> tags ?
The following code doesn't work.
<table>
<tr>
<logic:iterate id="myID" collection="pageRecords" property="UserDetail">
<td> <bean:write name="myID" property="id" /> </td>
</logic:iterate>
</tr>
</table>
I got JSP Exception: Cannot create iterator for this collection

Hi,
you can use the JSTL1.1 (or 1.0 as you want) in the following way:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
........
<table>
<c:forEach items="${requestScope.pageRecords}" var="row">
<tr><c:out value="${row.Id}"/></tr>
</c:forEach>
</table>
you can use "pageScope", "requestScope", "sessionScope" or
"applicationScope" depending on the "pageRecords" is stored.

Assuming you have a scoped Collection named "pageRecords":
Struts tags:
<logic:iterate id="myID" name="pageRecords">
<td> <bean:write name="myID" property="id" /> </td>
</logic:iterate>
JSTL:
<c:forEach var="user" items="${pageRecords}">
<c:out value="${user.id}"/>
</c:forEach>
