hi

i am having a TransientObjectException in my application

all related information is given bellow

I am using Hibernate version 2.1
I am using Oracle9i Enterprise Edition Release 9.0.1.1.1 - Production

Mapping document-----------------------------
<class name="com.diit.voffice.pfb.client.ClientAddressDto" table="client_add_info">

<id name="pkCode" column="PK_CODE">
<generator class="assigned"/>
</id>
<property name="address1" column="ADD1"/>
<property name="address2" column="ADD2"/>
<many-to-one name="country" column="CNT_CODE" not-null="true"/>
<many-to-one name="city" column="CITY_CODE" not-null="true"/>
<many-to-one name="area" column="AREA_CODE"/>
<property name="zipCode" column="ZIP_CODE"/>
<property name="userId" column="USER_ID"/>
<property name="userDateType" column="USER_DATE" type="date"/>
</class>

The Testing method from the test class---------------------

public void testDelete() throws Exception {
SessionFactory factory = (SessionFactory) ContextHolder.getInstance()
.get(ResourceNames.HIBERNATE_SESSION_FACTORY);
Session session = factory.openSession(pool.getConnection());
log.debug("\n\nTest DELETE...............");

ClientAddressDto dtoClone = (ClientAddressDto) dto.clone();
dto = (ClientAddressDto) dtoClone.clone();
businessObject.delete(session, dto, result);
log.debug("result=" + result);
log.debug(((ClientAddressDto) result.getResultData()));
assertTrue(result.getResultData() != null);
session.flush();

if (result.isSuccess()) {
session.connection().commit();
} else {
session.connection().rollback();
}

pool.releaseConnection(session.connection());
session.close();
}

Original Delete method which i am invoking from the test class-----------

public void delete(Session session, ClientAddressDto dto, Result result)
throws HibernateException {

if (dao.isExists(session, dto)) {
session.clear();
dao.delete(session, dto);
result.setActionMessage("message.deleted.success");
result.setSuccess();
}
else {
result.setActionError("error.record.notfound");
result.setFailure();
}

result.setResultData(dto);
}


The following is the stack trace given by JUnit------------------
