[Andromda-user] Hibernate POJOs

[javier . adorno]

I'm developing a remote client and I want to use the hibernate POJOs as domain Value Objects.
If my hibernate POJO does NOT contain another object (i.e. a Collection or an Object of a related Class) it works without problems.
But if use a hibernate POJO that contains another object I get the following error when returning the object to the remote client.

Exception in thread "main"


The class org/odmg/DCollection is inside the omdg-3.0.jar that is deployed whit the generated EAR.
Before returning the object I call getFoo() accesors to load the related Objects because I'm using lazy loading.
By the way I'm using Jboss 3.2.5.

I'll appreciate if someone could give me a hand

Regards

Javier
