Support class references when simplifying reference properties as elements #7

Open highsource opened 10 years ago

Abdull commented 9 years ago

Is this issue for cases such as:

<complexType name="oai_dcType">
  <choice minOccurs="0" maxOccurs="unbounded">
    <element ref="dc:title"/>
    <element ref="dc:creator"/>
    <element ref="dc:subject"/>
    <element ref="dc:description"/>
    <element ref="dc:publisher"/>
    <element ref="dc:contributor"/>
    <element ref="dc:date"/>
    <element ref="dc:type"/>
    <element ref="dc:format"/>
    <element ref="dc:identifier"/>
    <element ref="dc:source"/>
    <element ref="dc:language"/>
    <element ref="dc:relation"/>
    <element ref="dc:coverage"/>
    <element ref="dc:rights"/>
  </choice>
</complexType>

?

My use case is generating better Java classes for the OAI DC schema (better Java classes than those I get from the plain xjc command).

I have tried the simplify plugin by editing/annotating that OAI DC schema. But during the Maven build, I get Exceptions telling me that I'm using the simplify annotations at the wrong location.

No, what you want should already work.

This issue is about complex types annotated with jaxb:class/@ref.

Where do you hang your customizaton?

This is my custom_oai_dc.xsd:

https://github.com/highsource/jaxb2-basics/wiki/JAXB2-Simplify-Plugin#simplifying-references-property

Not that in the case of a reference property, you have to customize one of thexs:elements and not the xs:choice.

So customize one of your elements.

I tried different strategies (e.g., using an xjb file; directly annotating the XSD file etc.), but still get exceptions.

I have this same problem. Any solution?

highsource commented 8 years ago

Nope, but at least reproduced.

highsource commented 8 years ago

For some reason XJC does not attach customizations to these elements. I don't know, why, but it is as it is.

To work around, customize via the class, ex.:

  <jaxb:bindings schemaLocation="schema.xsd" node="/xs:schema/xs:complexType[@name='oai_dcType']">
    <simplify:property name="titleOrCreatorOrSubject">
      <simplify:as-element-property/>
    </simplify:property>
  </jaxb:bindings>
highsource commented 8 years ago

Documented: https://github.com/highsource/jaxb2-basics/wiki/JAXB2-Simplify-Plugin

But this is still NOT THIS ISSUE.

rochafrancisco commented 7 years ago

@Abdull did the workaround fix your issue? I have a similar problem.

lyhistory commented 5 years ago

I also struggled with the same issue, and finally I workaround it by using external conversion using https://javaee.github.io/jaxb-v2/
