Hi guys,
I use Hyperjaxb3 to generate JPA entities from XSD schema. I have a xsd:string type that I want to use for description text (text area in the UI):
<xsd:complexType name="Description">
<xsd:simpleContent>
<xsd:extension base="**xsd:string**">
<xsd:attribute name="abc" type="xsd:NCName" use="optional" />
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
Hyperjaxb3 generates class (entity) Description with attribute value, annotated like this:
@Basic
@Column(name = "VALUE_", **length = 255**)
public String getValue() {
return value;
}
The questions I have:
I saw that if I put xsd:maxLength restriction on xsd:simpleType, JPA @Column.length has the value of maxLength. How can I set xsd:rescriction on xsd:simpleContent that is xsd:extension of xsd:string? Do I have to define a complexType with xsd:resctriction that I will extend? And if yes, will Hyperjaxb generate @Column.length by my restriction. I tried following:
<xsd:simpleType name="DescriptionParent">
<xsd:restriction base="xsd:string">
<xsd:maxLength value="4096" />
</xsd:restriction>
</xsd:simpleType>
<xsd:complexType name="Description">
<xsd:simpleContent>
<xsd:extension base="DescriptionParent">
<xsd:attribute name="abc" type="xsd:NCName" use="optional" />
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
But the JPA column length is still 255.
Is it also possible to set in my JAXB customization (*.xjb file) the lenght of the column for given type (somehow let hyperjaxb know that this is the orm I want to use for my specific type)? Or is it totally out of the way and xsd:maxLength should be used (above) I managed to set it globally for Hyperjaxb customization:
Thanks for your help.
