Hi Leon, I took a look at the way you're setting up the mapping in the afterloads, and that looks to be fine to me. We have some test cases that do a similar reference mapping (with @address-id going to @id on an Address) that's set up in code that to works, so I'm not sure why your attribute isn't getting populated. If you send me your test case, I can walk through in the debugger and see what's going on. I would have to see the rest of your project to know if there's an issue. -Matt
During debugging I noticed that IndustrialFamily had no primary key (code). This was giving the exception. I could not define a primary key for IndustrialFamily in the workbench. Is this currently not supported? I tried to workaround this problem using afterload methods and doing this in Java. This is my code: public static void afterFamilyLoader(ClassDescriptor familyDescriptor) { familyDescriptor.setJavaClass(IndustrialFamily.class); familyDescriptor.addPrimaryKeyFieldName("@code"); } public static void afterProductLoader(ClassDescriptor productDescriptor) { XMLObjectReferenceMapping product = new XMLObjectReferenceMapping(); product.setAttributeName("industrialFamily"); product.setReferenceClass(IndustrialFamily.class); product.addSourceToTargetKeyFieldAssociation("@familyCode", "@code"); productDescriptor.addMapping(product); } I don't get a stacktrace any more. But now the family is null in my Product Object. Is there still something missing in my mapping?

Hello I have a problem (stacktrace) using the XML Object Reference Mapping in the workbench tool from EclipseLink 1.0M6. This is my xml data: <CatalogProduct code="123JI" name="BSN Lamp" type="Lamp" familyCode="BSN-BC4H"> ..... </CatalogProduct> <IndustrialFamilies> <IndustrialFamily code="BSN-BC4H" name="Family Lamps" productCategoryCode="Lamps"/> </IndustrialFamilies> I mapped this in the workbench as an XML Object Reference with Source Xpath=@familyCode and Target Xpath=@code. In the eclipselink documentation I read that XML Object Reference is only supported in Java and not in the workbench. Is this still the case? Running an unmarshall application in Eclipse, results in the following stacktrace: javax.xml.bind.UnmarshalException - with linked exception: [java.lang.ArrayIndexOutOfBoundsException: -1] at org.eclipse.persistence.jaxb.JAXBUnmarshaller.unmarshal(JAXBUnmarshaller.java:102) at com.philips.lighting.research.jaxb.UnmarshallXml.main(UnmarshallXml.java:31) Caused by: java.lang.ArrayIndexOutOfBoundsException: -1 at java.util.Vector.setElementAt(Unknown Source) at org.eclipse.persistence.oxm.mappings.XMLObjectReferenceMapping.buildReference(XMLObjectReferenceMapping.java:147) at org.eclipse.persistence.internal.oxm.XMLObjectReferenceMappingNodeValue.attribute(XMLObjectReferenceMappingNodeValue.java:91) at org.eclipse.persistence.oxm.record.UnmarshalRecord.startElement(UnmarshalRecord.java:600) at org.eclipse.persistence.internal.oxm.XMLRelationshipMappingNodeValue.processChild(XMLRelationshipMappingNodeValue.java:72) at org.eclipse.persistence.internal.oxm.XMLCompositeCollectionMappingNodeValue.startElement(XMLCompositeCollectionMappingNodeValue.java:89) at org.eclipse.persistence.oxm.record.UnmarshalRecord.startElement(UnmarshalRecord.java:558) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.startElement(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(Unknown Source) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(Unknown Source) at org.eclipse.persistence.internal.oxm.record.XMLReader.parse(XMLReader.java:99) at org.eclipse.persistence.internal.oxm.record.SAXUnmarshaller.unmarshal(SAXUnmarshaller.java:216) at org.eclipse.persistence.internal.oxm.record.SAXUnmarshaller.unmarshal(SAXUnmarshaller.java:193) at org.eclipse.persistence.oxm.XMLUnmarshaller.unmarshal(XMLUnmarshaller.java:274) at org.eclipse.persistence.jaxb.JAXBUnmarshaller.unmarshal(JAXBUnmarshaller.java:100) ... 1 more _______________________________________________ eclipselink-users mailing list eclipselink-users@xxxxxxxxxxx https://dev.eclipse.org/mailman/listinfo/eclipselink-users |
