Hello,
A co-worked of mine has the following situation:
He has a base class (LensBase) with a Component (DatePeriod). He then
derives from this base class (Lens) and wants to use AttributeOverride the
database mapping for the parent class's component. That is, Lens wants to
over-ride the database mapping for LensBase.effectiveDatePeriod:


<xsd:complexType name="DatePeriod">
<xsd:annotation><xsd:appinfo source="teneo.jpa">@MappedSuperclass
@Embeddable</xsd:appinfo></xsd:annotation>
<xsd:sequence>
</xsd:sequence>
<!-- Primitive Data Fields -->
<xsd:attribute name="start" type="xsd:date" use="required" />
<xsd:attribute name="end" type="xsd:date" use="required" />
</xsd:complexType>

<xsd:complexType name="LensBase">
<xsd:annotation>
<xsd:appinfo source="teneo.jpa">
@MappedSuperclass
</xsd:appinfo>
</xsd:annotation>
<xsd:sequence>
<xsd:element name="effectiveDatePeriod"
type="DatePeriod" minOccurs="0">
<xsd:annotation>
<xsd:appinfo source="teneo.jpa">
@Embedded
</xsd:appinfo>
</xsd:annotation>

</xsd:element>
</xsd:sequence>
</xsd:complexType>


<xsd:complexType name="Lens">
<xsd:annotation>
<xsd:appinfo source="teneo.jpa">
@Entity
@Table( name="CSA4521T" )
@AttributeOverrides({
@AttributeOverride(name="effectiveDatePeriod.start", column =
@Column(name="PRODUCT_EFF_DT")),
@AttributeOverride(name="effectiveDatePeriod.end", column =
@Column(name="PRODUCT_TERM_DT")),
@AttributeOverride(name="displayOrder", column =
@Column(name="DISPLAY_SORT_NBR")) })
</xsd:appinfo>
<xsd:documentation>
Lens Style Information
</xsd:documentation>
</xsd:annotation>
<xsd:complexContent>
<xsd:extension base="LensBase">
<xsd:sequence>
...
</xsd:sequence>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>


This doesn't work, it errors out with the name of the default hibernate
generated columns instead of the mapped ones.

Any ideas? Are we on the right track here?

Thanks!

-Alex

Hi Alex,
AttributeOverride of parent component types is not yet supported. Can you create a bugzilla for
this? Can you also post the exception stack trace you see?

It would be great if you can also post a complete xsd which contains this case.
