Frank,
actually XSD2JavaGenerator does not work in the case of any association type
that is navigable from both sides.
I have intentionally, just to test generator, made Customer-SoH association
navigable from both sides and generated code again cannot be compiled.
Regarding your comments on bidirectional references and containments, I know I
can get container using dynamic SDO API but I don't want to see in a code that
implements business logic any code that is related to protocols or data
implementation technologies.
Packing data to SOAP envelop or sendig data over IIOP is job of stubs and
scaletons and main stream priogrammer should not ever cast object to classes
related to those techologies. Based on the same principales, business
programmer should not be avere that object he/she is dealing with is actually
instance of some Hybernate proxy or SDO DataObject and should not ever cast
those objects to mentioned classes unless he/she develops some tools or similar
generic software.
And I do not want to use any dynamic API if I don't have to, so I prefer to
have typed Java API and SDO specification explicitally lists that support as
one of the major requirements. So SDO should support static API defined by XSD
schema.
I think Java business programmer should be familiar with UML class diagrams
that define domain and should get only corresponding POJOs to deal with. Code
dealing with data transport or object distribution or data persistance, where
BTW one technology is "cool" today and next day another one, should be hidden
in adapters, skeletons and stubs.
Next is complete XSD built automatically from attached UML.

Subject: Re: XSD2JavaGenerator and non-containment references
Miro,
Both sides of a relationship defined with sdoXML:oppositeProperty need to
be non-containment references. All containment references are implicitly
bidirectional (the reverse is the elements container), so you wouldn't
really want to use an IDREF element anyway - it's just duplicate
information.
To get the SoH from an SoL, you can call:
SoH soh = (SoH)sol.getContainer();
You could manually add a getOrder() (convenience) method in the generated
class like this:
SoH getOrder() { return (SoH)getContainer(): }
EMF has a way to generate this kind of method for you, but there's no
support for this in SDO.
Frank.
