Hi, Looking at the stack trace, I am quite puzzled. Given what you have provided so far, it is very hard for me to tell whether Castor is/is not including the roles property as part of the marshalling. All I know is that at your front-end, something is trying to obtain a handle to role entities through Hibernate, and when doing so, throws an exception that it fails to do so (as apparently the collection (defined as lazy-loaded) cannot be initialited successfully).
Can you show us what the output Castor's Marshaller generated looks like ? Werner > -----Original Message----- > From: Ralf Joachim [mailto:[EMAIL PROTECTED] > Sent: Samstag, 12.
