This is the error I encounter when try to initialize an object.

=======================================

80578 [24-05-2005 11:58:09] ERROR test.action.OutgoingAction - HibernateException
net.sf.hibernate.HibernateException: disconnected session
at net.sf.hibernate.collection.PersistentCollection.forceInitialization(PersistentCollection.java:339)
at net.sf.hibernate.Hibernate.initialize(Hibernate.java:255)
....

=======================================

This is part of the code I write...

public class OutgoingAction{
....
Hibernate.initialize(order.getOrderId());
List storeList = order.getOrderId().getList();
.....
}

Anyone see the above Hibernate exception before?

Thank you so much!

see http://forum.hibernate.org/viewtopic.php?t=942798

Thanks for your reply zesj.
I have use session.isConnected to check and I am quite sure that the
session is still connected.

However, I find a strange things is that I use isInitialized() to check that object before Hibernate.Initialize...

{
...
System.out.println(Hibernate.isInitialized(order.getOrderId()));
Hibernate.Initialize(order.getOrderId());
....
}

Its printout is True!!!!

>_<

try change

to

in documentation
http://www.hibernate.org/hib_docs/api/net/sf/hibernate/Hibernate.html#initialize(java.lang.Object)
initilize parameter is Object , not id.

Thanks zesj! That function works now! ^_^

However, that session is still seems strange....the following are part of my code....

public class OutgoingAction{

....
printOrder(session,order);
session.save(order);
session.flush();
outputOrder(order, deliveryList, session);
session.save(deliveryList);
session.flush();
.....

public void printOrder(Session session, OutgoingOrder order){
Hibernate.initialize(order.getOrderId());
List storeList = order.getOrderId().getList();
....

}

public void outputOrder(OutgoingOrder order, List deliveryList, Session session){
List compareList = order.getOrderId().getList();
List tempList = deliveryList;
.....
}
.....
}

Now another exception happens:
===============================================

at net.sf.hibernate.collection.Set.iterator(Set.java:130)
===============================================

Is that again I have to do Hibernate.Initialize(order) in the function outputOrder?

Thank you so much!!!

you can try:
1) if order.getOrderId() return ID(Long,integer, etc) , change to

2) if order.getOrderId() return Order object, continue with

3)try attach object in session before initialize
