1.public class UserRefData implements Serializable

2.public UserRefData (int id,int user_id,int ref_data_id ){

by: Srinivasu_VPosted on 2009-08-27 at 03:04:16ID: 25196196

Actually I'm getting the above exception while i'm executing the following lines in my JSP:

 <c:forEach items="${subEntitlements}" var="UserRefData"   varStatus="status">
   <c:choose>
     <c:when test="${UserRefData.ref_data_id == ReferenceData.m_RefDataID}">      

"subEntitlements" is a list which i'm returning from my controller class, after that its not identifying my bean name "UserRefData" & its property name ref_data_id. B'cos of this i'm getting the above Exception.
