Hi there!

I am a new Hibernate- User and have a problem. I generated my java classes from a xsd- file and uses JPA to fill my POJO's with MySQL- data. I came up to now relatively well with Hibernate and JAXB since now. At first I will show you the relevant parts of my xsd file, then I'll show the relevant classes and I hope someone can tell me how to annotate it.

XSD (Schema):
Code:
<xsd:element name="record" type="complexType.InventoryRecord"/>

<xsd:complexType name="complexType.InventoryRecord">
  <xsd:sequence>
    <xsd:element name="allocation" type="simpleType.Allocation" minOccurs="0"/>
    <xsd:element name="allocation-timestamp" type="xsd:dateTime" minOccurs="0"/>
    <xsd:element name="perpetual" type="xsd:boolean" minOccurs="0"/>
    <xsd:element name="preorder-backorder-handling" type="simpleType.InventoryRecord.PreorderBackorderHandling" minOccurs="0"/>
    <xsd:element name="preorder-backorder-allocation" type="simpleType.Allocation" minOccurs="0"/>
    <xsd:element name="in-stock-date" type="xsd:date" minOccurs="0"/>
    <xsd:element name="custom-attributes" type="sharedType.CustomAttributes" minOccurs="0"/>
  </xsd:sequence>
  <xsd:attribute name="product-id" type="simpleType.Generic.NonEmptyString.256" use="required"/>
  <xsd:attribute name="mode" type="simpleType.ImportMode" use="optional"/>
</xsd:complexType>

<xsd:complexType name="sharedType.CustomAttributes" mixed="false">
  <xsd:sequence>
    <xsd:element name="custom-attribute" type="sharedType.CustomAttribute" minOccurs="0" maxOccurs="unbounded"/>
  </xsd:sequence>
</xsd:complexType>
<xsd:complexType name="sharedType.CustomAttribute" mixed="true">
  <xsd:sequence>
    <xsd:element name="value" type="simpleType.Generic.String" minOccurs="0" maxOccurs="unbounded"/>
  </xsd:sequence>
  <xsd:attribute name="attribute-id" type="simpleType.Generic.NonEmptyString.256" use="required"/>
  <xsd:attribute ref="xml:lang"/>
</xsd:complexType>


I generate the XML without the CustomAttributes- part, because there is my problem... I dont get it to work to create the CustomAttributes- Part in my XML.
Here is a sample- XML that should be generated:
Code:
<records>
  <record mode="delete" product-id="!">
    <allocation>0.0</allocation>
    <allocation-timestamp>2001-12-17T09:30:47Z</allocation-timestamp>
    <perpetual>true</perpetual>
    <preorder-backorder-handling>none</preorder-backorder-handling>
    <preorder-backorder-allocation>0.0</preorder-backorder-allocation>
    <in-stock-date>1967-08-13</in-stock-date>
    <custom-attributes>
      <custom-attribute xml:lang="en-us" attribute-id="!">
        <value>String</value>
        <value>String</value>
        <value>String</value>
      </custom-attribute>
      <custom-attribute xml:lang="en-us" attribute-id="!">
        <value>String</value>
        <value>String</value>
        <value>String</value>
      </custom-attribute>
    </custom-attributes>
  </record>
</records>


The Generated Java- classes are:
Code:

// This is a container class for records
@Entity
@Table(name="dw_exp_inventory")
public class RecordCartrige {
    @Id
    @GeneratedValue
    @Column(name="rec_id")
    private long recId;

    @Embedded
    private ComplexTypeInventoryRecord record;
    ...
}


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "complexType.InventoryRecord", propOrder = {
    "allocation",
    "perpetual",
    "preorderBackorderHandling",
    "preorderBackorderAllocation",
    "inStockDate"
})
@Embeddable
public class ComplexTypeInventoryRecord {
    @XmlElement
    @Column
    protected BigDecimal allocation;
       
    @XmlElement
    @Column
    protected Boolean perpetual;
   
    @XmlElement(name="preorder-backorder-handling")
    @Column(name="preorder_backorder_handling")
    protected SimpleTypeInventoryRecordPreorderBackorderHandling preorderBackorderHandling;
   
    @XmlElement(name="preorder-backorder-allocation")
    @Column(name="preorder_backorder_allocation")
    protected BigDecimal preorderBackorderAllocation;
   
    @XmlElement(name="in-stock-date")
    @XmlSchemaType(name="date")
    @XmlJavaTypeAdapter(type=String.class, value=DateAdapter.class)
    @Column(name="in_stock_date")
    protected Date inStockDate;
   
    @XmlAttribute(name="product-id", required=true)
    @Column(name="product_id", nullable=false)
    protected String productId;
   
    @XmlAttribute
    @Column(nullable=false)
    protected String mode;

    // How I have to do this???
    @XmlElement(name = "custom-attributes")
    protected SharedTypeCustomAttributes customAttributes;
    ...
}


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sharedType.CustomAttributes", propOrder = {
    "customAttribute"
})
public class SharedTypeCustomAttributes {
    protected List<SharedTypeCustomAttribute> customAttribute;
    public List<SharedTypeCustomAttribute> getCustomAttribute() {
        if (customAttribute == null) {
            customAttribute = new ArrayList<SharedTypeCustomAttribute>();
        }
        return this.customAttribute;
    }
}


@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "sharedType.CustomAttribute", propOrder = {
    "content"
})
public class SharedTypeCustomAttribute {
    @XmlElementRef(name="value", namespace = "http://www.demandware.com/xml/impex/inventory/2007-05-31", type = JAXBElement.class)
    @XmlMixed
    protected List<Serializable> content;

    @XmlAttribute(name="attribute-id", required = true)
    protected String attributeId;

    @XmlAttribute(namespace="http://www.w3.org/XML/1998/namespace")
    @XmlJavaTypeAdapter(CollapsedStringAdapter.class)
    @XmlSchemaType(name="language")
    protected String lang;
    ...
}


I get the RecordCartrige- Objects with the following code:
Code:
List<RecordCartrige> recordList = (List<RecordCartrige>) getSession().createQuery("from " + RecordCartrige.class.getName()).list();
Iterator<RecordCartrige> iterator = recordList.iterator();

and later I can iterate through the List to write my XML:
Code:
while(iterator.hasNext()) {
  RecordCartrige recordCartrige = iterator.next();
  JAXBElement<ComplexTypeInventoryRecord> record = jaxbObjFactory.createRecord(recordCartrige.getRecord());
  getMarshaller().marshal(record, getWriter());
}


In Class "ComplexTypeInventoryRecord" there is the field customAttributes which is from type "SharedTypeCustomAttributes". What I have to do now? SharedTypeCustomAttributes has a Collection/List of SharedTypeCustomAttribute- Objects and is only a "container" for SharedTypeCustomAttribute. For Example: Must I add the Entity- Annotation to the SharedTypeCustomAttributes- Class? The values for one CustomAttribute are in a different table as the record- values (they have their own DB-table) It would be nice if someone could help me...

Thanks!
Danny
