Hi everybody, I am aware that this is totally OT, but I'd be really grateful for any answers, hints, best practices, links, whatever. My problem is as follows:
I am using Hibernate/Spring to load domain objects (DOM) from my database, then I use these DOMs to display information on the web. Great. Now I want to add web services and all of a sudden this won't really work anymore. What I'd like to do is use JAXB2 to marshall my DOMs, transfer them using XFire and reasemble them via JAXB2 on the client side. For simple objects this works nicely yet when you have cyclic dependencies (parent: private List<Abc> children / each child: private Abc parent), JAXB cannot handle this. I've experimented with afterUnmarshal() from the JAXB API and also with onCycleDetected() from JAXB RI 2.1, yet both approaches do not really appeal to me. Do I need to introduce an DTO layer, that does not have these cyclic dependencies or is there a cleaner, more elegant approach to solve this? As I already stated, I'd be really greatful for your input. Regards, Tom
