Display Oracle date in a given format with JSTL using Hibernate - spring

Question

I have a date field in a table in an Oracle(10g) database which is mapped by TemporalType.TIMESTAMP in Hibernate like,
#Column(name = "DISCOUNT_START_DATE")
#Temporal(TemporalType.TIMESTAMP)
private Date discountStartDate;
//Setter and getter.
It fetches dates and displays like the following (which are already inserted into the database),
2012-08-29 01:53:10.0
2012-08-20 02:32:22.0
2012-08-01 14:00:21.0
2012-08-20 13:58:01.0
2012-08-30 04:14:13.0
2012-09-10 16:13:45.0
When I attempt to display them using JSTL like,
<fmt:formatDate pattern="dd-MMM-yyyy hh:mm:ss" value="${row.discountStartDate}"/>
it throws an exception,
javax.el.ELException: Cannot convert 2012-08-29 01:53:10.0 of type
class java.lang.String to class java.util.Date
I have tried to change TemporalType.TIMESTAMP to TemporalType.DATE but didn't work.
Earlier, it was working with XML mapping files (xxx.hbm.xml) like.
<property name="discountStartDate" type="date">
<column length="7" name="DISCOUNT_START_DATE"/>
</property>
but with annotations, it failed. How to apply this format dd-MMM-yyyy hh:mm:ss to display those dates in JSP using JSTL?
EDIT:
The following is the Discount entity class which is mapped with the DSCOUNT table in Oracle (the equals() and the toString() methods have been omitted).
#Entity
#Table(name = "DISCOUNT", catalog = "", schema = "WAGAFASHIONDB")
public class Discount implements java.io.Serializable
{
private static final long serialVersionUID = 1L;
#Id
#Basic(optional = false)
#Column(name = "DISCOUNT_ID", nullable = false, precision = 35, scale = 0)
#SequenceGenerator(name = "discountIdSequence", sequenceName = "DISCOUNT_SEQ", allocationSize=1, initialValue=1)
#GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "discountIdSequence")
private Long discountId;
#Column(name = "DISCOUNT_CODE", length = 100)
private String discountCode;
#Column(name = "DISCOUNT_PER", precision = 35, scale = 2)
private double discountPer;
#Column(name = "DISCOUNT_START_DATE")
#Temporal(TemporalType.TIMESTAMP)
private Date discountStartDate;
#Column(name = "DISCOUNT_END_DATE")
#Temporal(TemporalType.TIMESTAMP)
private Date discountEndDate;
#OneToMany(mappedBy = "discountId", fetch = FetchType.LAZY)
private Set<OrderTable> orderTableSet;
public Discount() {
}
public Discount(Long discountId) {
this.discountId = discountId;
}
public Long getDiscountId() {
return discountId;
}
public void setDiscountId(Long discountId) {
this.discountId = discountId;
}
public String getDiscountCode() {
return discountCode;
}
public void setDiscountCode(String discountCode) {
this.discountCode = discountCode;
}
public double getDiscountPer() {
return discountPer;
}
public void setDiscountPer(double discountPer) {
this.discountPer = discountPer;
}
public Date getDiscountStartDate() {
return discountStartDate;
}
public void setDiscountStartDate(Date discountStartDate) {
this.discountStartDate = discountStartDate;
}
public Date getDiscountEndDate() {
return discountEndDate;
}
public void setDiscountEndDate(Date discountEndDate) {
this.discountEndDate = discountEndDate;
}
public Set<OrderTable> getOrderTableSet() {
return orderTableSet;
}
public void setOrderTableSet(Set<OrderTable> orderTableSet) {
this.orderTableSet = orderTableSet;
}
}
In JSP, the following loop is used to display data (reducing the code complexity).
<c:forEach var="row" items="${list}" varStatus="loop">
<fmt:formatDate pattern="dd-MMM-yyyy hh:mm:ss" value="${row.discountStartDate}"/>
</c:forEach>
and in Spring DAO, the list which is iterated by the preceding loop is simply retrieved as follows.
#SuppressWarnings("unchecked")
public List<Discount>getList(int currentPage, int rowsPerPage)
{
List<Discount> list = sessionFactory.getCurrentSession()
.createQuery("from Discount order by discountId desc")
.setFirstResult(currentPage)
.setMaxResults(rowsPerPage).list();
for(Discount d:list)
{
System.out.println(d.getDiscountStartDate()+" : "+d.getDiscountEndDate());
}
return list;
}
The preceding loop is just for the sake of demonstration. It displays the dates from the table as follows.
2012-08-29 01:53:10.0 : 2012-08-31 01:53:16.0
2012-08-20 02:32:22.0 : 2012-08-24 02:34:36.0
2012-08-01 14:00:21.0 : 2012-08-31 14:01:30.0
2012-08-20 13:58:01.0 : 2012-08-21 13:58:20.0
2012-08-30 04:14:13.0 : 2012-11-23 16:21:57.0
2012-09-10 16:13:45.0 : 2012-10-26 16:13:39.0
2012-08-22 16:06:23.0 : 2012-08-15 16:06:17.0
2012-08-22 10:35:04.0 : 2012-08-17 10:34:56.0
2012-08-17 10:35:29.0 : 2012-08-10 10:35:35.0
2012-10-08 10:35:56.0 : 2013-03-08 10:35:49.0
