Max,
Thanks your quick reply.
I follow your instruction to try again but still same error.
the combobox hibernate version is 4.0 when the first time I create the console configuration.
I even create new one but still can not open session factory.
I can open "Configuration" & "Database" node.
I can do reverse engineering to generate domain class.
My application run properly.
My application can store data to db and retrieve data from db.
I only can't open "Session Factory" node.
