java - error populating a table using jstl -


i getting following error when trying populate table in view.jsp using jstl access list of objects stored in request object of viewservlet:

/web-inf/jsp/admin/view.jsp (line: 34, column: 16) attribute value invalid tag foreach according tld   

can show me how fix code populate table correctly without error?

here relevant parts of view.jsp:

<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>          <table>         <!-- here should go titles... -->             <tr>                 <th>type</th>                 <th>number</th>                 <th>id</th>             </tr>             <c:foreach begin="1" end= "${ no }" step="1" varstatus="loopcounter"     value="${coursesummaries}" var="coursesummary">             <tr>                 <td>                     <c:out value="${coursesummary.coursetype}" />                 </td>                 <td>                     <c:out value="${coursesummary.numunits}" />                 </td>                 <td>                     <c:out value="${coursesummary.id}" />                 </td>             </tr>             </c:foreach>         </table> 

here relevant parts of viewservlet.java:

protected void doget(httpservletrequest req, httpservletresponse resp)  throws servletexception, ioexception {    string idstring = req.getparameter("id");    long id = new long(idstring);    list<coursesummary> coursesummaries = new coursesummarydao().findall(id);    req.setattribute("coursesummaries", coursesummaries);    jsp.forward(req, resp); }   

and here entire stack trace:

you trying use value attribute, not valid attribute <c:foreach> tag. perhaps meant use items:

<c:foreach begin="1" end= "${ no }" step="1" varstatus="loopcounter"            items="${coursesummaries}" var="coursesummary"> 

see <c:foreach> oracle doc list of valid attributes.

apart that, don't understand intent of using begin, end, , step, attribute, given iterating on collection. aren't using them. , don't need them imho.
