In struts+hibernate this kind of structure, is should not pass the PO that hibernate produces directly to JSP, whether he is iterator, or list, this is a design error. Let me talk about the data representation for each layer in the Java EE architecture: The data representation of the Web layer is Formbean, and the data comes from the HTML Form POST The data re

Properties of type Java.util.Collection or java.util.List can also be persisted using the "bag" semantics. The collection used for persistence, except for the collection interface, cannot retain any semantics attached to the class that implements these interfaces (for example, the iteration order that Linkedhashs
