Hello Greg,
Your solution works fine.
With a lot of Lazy Loading and circular relations
I have the idea to include the decision which relations should be
really loaded
and which should be nulled
in the Dao.Do you know if there is already a professional solution for
this usage?

Hi,
I think there is no common pattern. It solely depends on your usage
scenario. If you don't need to use a reverse side of the relationship in
your business logic, I would recommend removing that part.
Mind some of the intricacies though e.g. if you remove the parent reference
field in child
Anyway I'm curious if you keep your Hibernate session _open_ between two
HTTP Requests (second is calling String-template servlet? until View is
completely rendered) ?
Do you use open-session-in-view pattern or any other ? Conversations
spanning several request-response cycles ?
I am using Hibernate 4.1.8-Final and cocoon 3.0.0-beta-1-SNAPSHOT.
But why you ask?

Another kind of hack (if you cannot modify entity sources and they are
not external .xml files) would be setting all child objects' parent
references to null _before_ serializing that data.
Lets say you got: Author and Book entites with One-To-Many relationship.
You retrieve the entities from db
Thanks Greg,That's the idea as long as I don't save the bean there is no
problem
with the database. And such methods I already use with Lazy loading
between two requests.

Yup, Lazy loading will cause problems in this scenario. How about making
Hibernate session readOnly ? :)

I am using cocoon RestController to present my Hibernate Mysql data in
pdf files.
The Hibernate structure has cirular relationships, so when I give the
structure to the URLResponse there are endless StringBuilder calls.Do
you have an idea how to solve this problem.One idea would be to present
