Hi,
In my DB column has BLOB field. I have to convert my own POJO class from BLOB.
Conversion process is BLOB --> java.util.Map ---> POJO.

How to map my own POJO in hbm.xml file

I am facing this problem like

ERROR]22 Feb 2012 13:33 OnTime --> DashBoradDAOImpl:2028 --> getGlobalDashBorad(UserLoginVO)

Criteria criteria = session.createCriteria(ViewUserEvents.class);

List<ViewUserEvents> eventList = criteria.list();

ProjectVO projectVO = alertMap.get(elanEvent.getProjectId());
if (EventStreamDAOImpl.ALERT_COLLS.contains(elanEvent
.getUserEventForm().getFormType()))
projectVO.setAlertCount(projectVO.getAlertCount() + 1);
else
projectVO.setNotifyCount(projectVO.getNotifyCount() + 1);
}


<hibernate-mapping>
<property name="userEventForm" type="com.efycaci.ezone.eventstream.hbm.UserEvent">
<column name="EVENT_DATA" />
</property>
</class>
</hibernate-mapping>
