Changing an <element-tag> to an "attribute"
As seen in the Basic Table example, the DBWSBuilder-generated eclipselink-dbws-schema.xsd file derives <element-tag> names from the Database table metadata:
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
>
<xsd:complexType name="empType">
<xsd:sequence>
<xsd:element name="empno" type="xsd:int" xsi:nil="false"/>
<xsd:element name="ename" type="xsd:string" xsi:nil="true"/>
<xsd:element name="job" type="xsd:string" xsi:nil="true"/>
<xsd:element name="mgr" type="xsd:int" minOccurs="0" xsi:nil="true"/>
<xsd:element name="hiredate" type="xsd:dateTime" xsi:nil="true"/>
<xsd:element name="sal" type="xsd:decimal" xsi:nil="true"/>
<xsd:element name="comm" type="xsd:int" minOccurs="0" xsi:nil="true"/>
<xsd:element name="deptno" type="xsd:int" xsi:nil="true"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
<xsd:schema

<xsd:complexType name="empType">
<xsd:sequence>
<xsd:element name="empno" type="xsd:int" xsi:nil="false"/>
<xsd:element name="ename" type="xsd:string" xsi:nil="true"/>
<xsd:element name="job" type="xsd:string" xsi:nil="true"/>
<xsd:element name="mgr" type="xsd:int" minOccurs="0" xsi:nil="true"/>
<xsd:element name="hiredate" type="xsd:dateTime" xsi:nil="true"/>
<xsd:element name="sal" type="xsd:decimal" xsi:nil="true"/>
<xsd:element name="comm" type="xsd:int" minOccurs="0" xsi:nil="true"/>
<xsd:element name="deptno" type="xsd:int" xsi:nil="true"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
It is possible to change an <element-tag> to an "attribute" with a o.e.p.tools.dbws.NamingConventionTransformer
In the eclipselink-dbwsutils.jar, there are built-in transformers that form a Chain-of-Responsibility
In the org.eclipse.persistence.tools.dbws.NamingConventionTransformer services file, the transformer chain is listed in order:
- org.eclipse.persistence.tools.dbws.ToLowerTransformer
- org.eclipse.persistence.tools.dbws.TypeSuffixTransformer
- org.eclipse.persistence.tools.dbws.SQLX2003Transformer
