[eclipselink-users] XML Composite Object Mapping Problem

["den.ty" <dty7@xxxxxxxxx>]

Hi, 

I'm new to Eclipselink and I'm having trouble getting an XML mapping
working. 

I have the following Java classes:

    public class Response {
        List<ResourceStatus>  rs;
        List<ResourceLocation>  rl;    
        ...
    }

    public class ResourceStatus {
        private String id;
        private String status;
        ...
    }

    public class ResourceLocation {
        private String id;
        private Point posn;
        ...
    }

My XML doc is:

    <remc:Response> 

      <remc:ResourceStatusLocations> 
        <remc:ID>AAA</remc:ID>
        <remc:Status>0</remc:Status>  
        <remc:Location>                 
          <common:Coordinate>                
            <common:X>5.0</common:X>   
            <common:y>5.0</common:y> 
          </common:Coordinate>
        </remc:Location>
      </remc:ResourceStatusLocations>

      <remc:ResourceStatusLocations>          
        <remc:ID>BBB</remc:ID>
        <remc:Status>2</remc:Status>   
        <remc:Location>                 
          <common:Coordinate>                  
            <common:X>7.0</common:X>   
            <common:y>7.0</common:y> 
          </remc:Coordinate>
        </remc:Location>
      </remc:ResourceStatusLocations>

    </remc:Response>

and the equivalent objects should be 

    Response
        rl  ["AAA", (5.0, 5.0)], ["BBB", (7.0, 7.0)]

        rs  ["AAA", "0"],    ["BBB", "2"]

    
In workbench (EclipseLink Workbench v2.0.2), I have:

      Descriptor Response               --> context =
schema::nnn//element::remc:Response

            - Attribute ResourceLocation mapped as a composite collection:
                - xpath                = remc:ResourceStatusLocation
                - Reference descriptor = ResourceLocation

      Desciptor ResourceLocation        --> context =
schema::nnn//complexType:remc:ResourceStatusLocation

            - Attribute coordinate mapped as composite object using
customiser code
            
                final XMLCompositeObjectMapping mapping = new
XMLCompositeObjectMapping();
                mapping.setAttributeName("coordinate");
                mapping.setXPath("remc:Location/common:Coordinate");
                mapping.setReferenceClass(Point.class);
                descriptor.addMapping(mapping);            
     
 However, when marshalling the object to XML, I've got the id and statuses
mapped ok but the locations are missing:. 
 
     <remc:Response>
 
        <remc:ResourceStatusLocations>
           <remc:Status>0</remc:Status>
           <remc:ID>AAA</remc:ID>
        </remc:ResourceStatusLocations>
 
        <remc:ResourceStatusLocations>
           <remc:Status>2</remc:Status>
           <remc:ID>BBB</remc:ID>
        </remc:ResourceStatusLocations>
 
     </remc:Response>

 I have verified that the customiser code is being called and that the
Point.class matches the Coordinate element.
 
Is this the right approach to take or am I missing something obvious here?  
 
Thanks
Den
