Ah , i see. Thanks Ralf for the clear explanation, i know which path i have to choose now.

Hi Abangkis, it is not neccessary for Castor to marshal/unmarshal objects that they have been generated by Castors code generator. Apart of marshaling/unmarshalling classes generated by Castor you can also marshal/unmarshal any POJO out of the box, we call that introspection. But with introspection you do not have control over the XML. To be able to control the XML marshalled/unmarshalled there is a third mode where you need to define a mapping file that tells Castor where and how a property should apear in your XML. The mapping approach, in theory,would be what you need to marshal the POJOs generated by Hibernate. But there is one major problem with the mapping approach: When loading objects from database Hibernate wraps them with dynamic proxis using cglib or some similar libs. This behaviour of Hibernate successfully prevents Castor from detecting the right class and marshal this objects. We have identified this problem and intend to provide a workaround in Castor but currently it is not solved. Over all I think the best solution at the moment will be to code up some classes that convert the hierarchy of Hibernate generated classes into one of Castor generated classes.
