Rick,
Thanks for your response. I tried the same but it's not sorting right.
Please see below and suggest what's the mistake?
have an obj Customer
Customer has attributes
name - String
createDate - Date
in struts action
DateFormat dateFormat = new SimpleDateFormat("MM-dd-yyyy");
custObj1.setCreateDate(dateFormat.parse("7-1-2005"));
and created list of cust objects
in jsp
<display:table name="sessionScope.Form1.custList" id="custRow"
requestURI="PrepareAction.do" defaultsort="2" defaultorder="descending"
pagesize="6">
.......
......
<!-- Create Date -->
<display:column titleKey="lbl.crdate" sortable="true" >
<c:if test="${custRow.createDate != null}" >
<fmt:formatDate value="${custRow.createDate}" pattern="MM-dd-yyyy"
var="crtDate"/>
<c:out value="${crtDate}"/>
<!--c:out value="${custRow.createDate}"/-->
</c:if>
</display:column>
..........
............
</display:table>
Thanks.
