Current docs: http://wiki.eclipse.org/Configuring_a_Relational_Direct-to-XMLType_Mapping_(ELUG)

Although no useful code currently exists.

Comment 2 Doug Clarke 2008-02-19 10:46:02 EST

NATIVE configuration:

DirectToXMLTypeMapping mapping = new DirectToXMLTypeMapping();

// configure mapping. This example maps a
mapping.setAttributeName("resume");
mapping.setShouldReadWholeDocument(false);
descriptor.addMapping(mapping);

Configurable items to consider:
1. Attribute field/property
2. Lazy-loading (fetch-group)
3. Read Whole Document
4. read-only: Handled through @Column's insertable/updatable
5. Custom properties

NOTE: I am not sold on @BasicXML but it is a starting point for discussion since DirectToFieldMapping is annotated with JPA's @Basic

@BasicXML(fetch=FetchType.LAZY, optional=true, readWhole=true)
@Access(AccessType.PROPERTY)
@AccessMethods(get="getXMLDoc", set="setXMLDoc")
@Properties({
   @Property(name="x", value="y")
})
@Column(name="XML_DOC")
private String document


Reflecting this same example in XML might look like:

<basic-xml name="document" fetch="LAZY" optional="true" read-whole="true">
     <access type="PROPERTY"/>
     <access-methods get="getXMLDoc" set="setXMLDoc"/>
     <properties>
        <property name="x" value="y"/>
     </properties>
</basic-xml>

Comment 6 Gordon Yorke 2011-08-29 13:14:32 EDT

Instead of an entire new annotation why not follow the @LOB pattern and create an augmenting annotation for @Basic?  Like @XML or @JDBCType("XML")

Comment 7 Shaun Smith 2011-08-29 14:50:32 EDT

When defining an XMLType mapping using the native API, DDL generation fails when the column definition on the field is not specified [1].  Here's Doug's example with an additional line that resolves the problem:

DirectToXMLTypeMapping mapping = new DirectToXMLTypeMapping();

// configure mapping. This example maps a
mapping.setAttributeName("resume");
mapping.getField().setColumnDefinition("XMLTYPE");
mapping.setShouldReadWholeDocument(false);
descriptor.addMapping(mapping);

DDL generation need to be included in this enhancement.
