Hi Gilberto,
The generated-value element does not provide an attribute named
"pk-column-value", thus, the schema validator validating your orm.xml file
is throwing an exception.
This line is the culprit:
<generated-value strategy="TABLE" generator="table_generator"
pk-column-value="person"/>
The schema definition for generated-value is as follows:
<xsd:complexType name="generated-value">
<xsd:annotation>
<xsd:documentation>
@Target({METHOD, FIELD}) @Retention(RUNTIME)
public @interface GeneratedValue {
GenerationType strategy() default AUTO;
String generator() default "";
}
</xsd:documentation>
</xsd:annotation>
<xsd:attribute name="strategy" type="orm:generation-type"/>
<xsd:attribute name="generator" type="xsd:string"/>
</xsd:complexType>
The pk-column-name can only be specified on the table generator itself. I
don't think it is possible to override the pk-column-name at an attribute
level - certainly not via generated-value. According to the JPA 2.0 spec:
<spec>
3. The sequence-generator, table-generator, named-query,
named-native-query and sql-result-set-mapping elements are global
to the persistence unit. It is undefined to have more than one
sequence-generator or table-generator of the same name in the same
or different mapping files in a persistence unit.
</spec>
Once a table generator is defined, there can/should only be one definition
for the persistence unit. You can define multiples with a different
pk-column-name values, but the table-generator name needs to be unique.
hth,
