I've started playing with this and it seems to work correctly. (More 
testing needed) But one issue I came across was in the generated Client 
objects. 

My server side object looks as follows:

public class QuoteDTO {
@XmlAttribute @XmlIDREF
protected CustomerDTO customer;


But my generated Client object looks as follows:
public class QuoteDTO {
@XmlAttribute
@XmlIDREF
protected Object customer;


So now when my client attempts to access the customer the specific data 
type is lost. Is there any work around for this?

Thanks...

Re: bi-directional relationships

2008-04-11 Thread Christopher . Mathrusse 
I've begun to play with this type of implementation, using the @XmlIDREF 
and @XmlAttribute annotations and I've found a few issues.

1) As stated below, your client generated classes have the references to 
parent objects defined as data type Object. (an annoyance but workable)
2) As stated in the documentation: You'd also need to ensure that the 
referenced objects are contained somewhere else (like in the Root class in 
this case), or else Bar objects will never be marshalled. 

This one is difficult. I have a parent class that I return from my 
Services methods that contain all the information associated to the user 
and the request:
UserAcct - Quote - SalesResp

When this gets returned to the client the objects are just as the server 
sent them back.  But when I send a child object back over to the server 
all the references to the parents are lost.

Example:  addSalesRep(SalesRepDTO salesRep) {
...

The SalesRep object no longer has the parent Quote. That is because the 
original container no longer exists. I would need to define a new contain 
to be used to hold the object structure. 

I've tried several things to get around this, like placing a 
@XmlRootElement on my SalesRepDTO class on both the server and client 
classes but to no avail. There just doesn't seem to be a way to make this 
work how I would expect it to. The references to the parents are always 
lost when sending the objects from the client to the server.

Any suggestions?

Chris, for advanced JAXB questions, you might just want to go ahead and
ask on the Sun forum[1].  We use their JAXB, and the JAXB specialists
tend to congregate on that site.
