JAXB annotations are pretty simply used. There is an example project here.
| Annotation | Placement |
|---|---|
@XmlAccessorType |
The JAXB plugin annotates property fields. |
@XmlRootElement |
Both interface and implementation are annotated as element roots. |
@XmlElement |
All properties are annotated with this. |
Currently, inheritance is handled through JAXB. There are no discriminator values. The example used uses MOXy, and requires no special annotation.
Unions are handled through a union class annotated as a simple JAXB object. Custom serializers are not necessary.
