Subclasses if an inside element is different

[gufux]

Hi,

I have an issue with binding and class inheritance based on an internal element of XML schema. I have the following classes:

----------------------------------------------------------

public class Profile {
    protected UniqueId profileId;
}

public class Traveller extends Profile {
    protected TravellerName name;
    ....
}

public class Company extends Profile {
   protected CompanyName name;
   ....
}
------------------------------------------------------------

and XML messages like that:

1) <Profile>
      <UniqueId type="1" />
       <TravellerName>Davide</TravellerName>
   </Profile>
2) <Profile>
      <UniqueId type="1" />
       <CompanyName>IBM</ComapnyName>
   </Profile>

So I want to use only instances of Traveller and Company depending if in XML inside the <Profile> i have <TravellerName> or <CompanyName>.
I've tried with abstract classes and "extends" but there isn't a solution because when JibX have to bind the <Profile> it doesn't know the inside element and the correct
instance depend on that element.

I'have spent many time on this problem and so I would know if it's me that haven't found the right solution or in fact in Jibx simply I can't do that... anyone have any suggestions?

Thanks

Davide.

Hi there,

 

I also faced a similar issue. I ended up writing a custom marshaller and unmarshaller since I couldn’t find an inbuilt solution in Jibx for this.

A suggestion -
Shouldn't your models reflect how the xml is laid out?
If you remodel the Profile class be an enclosing class and has a
reference to a ProfileType abstract class whose concrete instances are
Traveller & Company then you will find the jibx mappings very straight
forward to implement.

public class Profile{
    ...
    public ProfileType profileType;
    ...
}

public abstract class ProfileType{...}

public class Traveller extends ProfileType{...}
