Gustavo,
Can you tell us a little more about your
solution, maybe show us a little bit of the interceptor?
Thanks,
Cezar

Hi Cezar,
I use Interceptor to instantiate a Entity without Default Constructor, in relationship n-n or 1-n to populate a array of XMLBeans and not PersistSet of Hibernate and to return a appropriate instance of object that implements a interface mapped in .hbm. Because XMLBeans use Factory in interface to create a new instance, and hibernate use a default constructor to create a new instance.
I set class attribute of my .hbm.xml to interface (XMLObject), and interceptor return a instance of object that hibernate will used do populate or get attributes.
I can send a sample or my framework tonight , here i don't have the source code, if you want.
This solution is part of a ESB and framework created to attend a client. The same object (XMLObject) is used in n layers, persistence, domain, service, and interface.
When decided to use XMLBeans in project, i had very problems to use him in persistence tier, ; and used Xmlbeans with DTO unique in service layer, need more work of programmers, using interceptor we optimized work with a good performance.
I'm writing a papper about this solutions, but doesn't have time to finalize him.
Best regards.

Hi,
can someony suggest me a persistence soloution for xmlbeans objects? I'd
like to use db4o, but I only found posts of people who had problems with
xmlbeans and db4o together.
Id'; like to use some kind of embedded soloution rather than an
object-to-RDBMS converter.
Thanks,
Jan
