Here is the hibernate dao class name called ActionsDao
public class ActionsDao {
public Session session;
public ArrayList<Actions> getActions() {
session = Util.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
try {
#SuppressWarnings("unchecked")
ArrayList<Actions> actionsList = (ArrayList<Actions>) session
.createQuery("from Actions").list();
tx.commit();
boolean found = false;
for (Actions actions : actionsList) {
Actions action = new Actions();
action.setId(actions.getId());
action.setAction(actions.getAction());
action.setActual(actions.getActual());
action.setAssignedBy(actions.getAssignedBy());
action.setAssignedTo(actions.getAssignedTo());
action.setScheduled(actions.getScheduled());
action.setOutcome(actions.getOutcome());
action.setStatus(actions.getStatus());
actionsList.contains(action);
found = true;
}
if (found) {
return actionsList;
} else {
return null;
}
} catch (Exception e) {
System.out.println("Error In getActions() -->" + e.getMessage());
return (null);
} finally {
session.close();
}
}
}

Here is the bean class i am developing name called Actions.
#ManagedBean(name = "actions", eager = true)
#SessionScoped
public class Actions implements Serializable {
private static final long serialVersionUID = 1L;
private int id;
private String action;
private String assignedTo;
private String assignedBy;
private Date scheduled;
private Date actual;
private String outcome;
private String status;
//write here setter & getter methods of the above properties
public ArrayList<Actions> getMessages() {
ActionsDao dao = new ActionsDao();
return dao.getActions();
}
}
you can use the annotations or hbm file that yours choice to map the bean class.
Here i am using only mapping file why because, first i am trying to create annotations but it raised some problems that jar files are some problem.your using the correct jar files that not a problem you can continue the annotations otherwise hbm file is best.
