JaxB fixed value annotation doesn't work

Hi,

I have XSD schema like this:

<xsd:annotation>
  <xsd:appinfo>
    <jaxb:globalBindings fixedAttributeAsConstantProperty="true" />
  </xsd:appinfo>

...

<xsd:complexType name="something_here">
  <xsd:complexContent>
    <xsd:restriction base="genericObject">
      <xsd:attribute name="type" type="xsd:string" fixed="FixedValue" use="required"/>
    </xsd:restriction>
  </xsd:complexContent>
</xsd:complexType>

I use Tools/JAXB/Generate Java Code From Xml Schema Using JAXB

By default this is checked and I leav it this way:

- Make generated files read-only

- Add necessary libraries

- Do not generate header

And when I click Ok it generates classes but...

This fixed value is not fixed. Why?

Hi,

Here is complete schema. I don't get fixed value for object007 (it should be constant "FIXED_VALUE_5" but it is not in class Object007).

Also, not only fixed value are not fixed but I have problem with List.

For example:

    ObjectFactory factory = new ObjectFactory();
    Object007 obj = factory.createObject007();
    obj.setId("id1");
    Medatada006 meta = factory.createMedatada006();
    Attr005 attr = factory.createAttr005();
    attr.setName("aaa");
    attr.setValue("bbb");
    meta.getAttr().add(attr);
    Event012 event = factory.createEvent012();
    event.setObject(obj);
    event.setAny(meta);
    JAXBElement<GenericEvent> genericEvent = factory.createEvent(event);


    JAXBContext jaxbContext  = JAXBContext.newInstance( Event012.class );
    Marshaller jaxbMarshaller   = jaxbContext.createMarshaller();
    StringWriter sw = new StringWriter();
    jaxbMarshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
    jaxbMarshaller.marshal(event, sw);
    System.out.println(sw.toString());

And I get this:

[EL Warning]: 2018-12-14 18:09:40.035--XMLAnyObjectMappingNodeValue: The undefined document root element of a referenced object [XMLDescriptor(test2.model.Medatada006 --> [])] is ignored during marshalling with an any collection|object mapping.

 

<?xml version="1.0" encoding="UTF-8"?><event xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="Event012"><object id="id1" xsi:type="object007"/></event>

Because, Medatada006 and Event012 didn't created properly, there is no information that medatada is also element wripping attrributes element.

Also Medatada006 has a list of attributes even if there is ENUMERATION in schema for attribute.
