sample code:


{code:java}

// DOMAIN CODE

@XmlRootElement(name = "Demo")
@XmlType
@XmlAccessorType(XmlAccessType.FIELD)
@DomainObject(nature=Nature.VIEW_MODEL, editing=Editing.ENABLED)
@Log
public class TemporalDemo extends DemoStub {

    @PostConstruct
    public void initDefaults() {
        
        log.info("TemporalDemo::initDefaults");
        
        javaLocalDate = LocalDate.now();
        javaLocalDateTime = LocalDateTime.now();
    }
    
    @XmlJavaTypeAdapter(value = LocalDateAdapter.class)
    @XmlElement @Getter @Setter private LocalDate javaLocalDate;
    
    @XmlJavaTypeAdapter(value = LocalDateTimeAdapter.class)
    @XmlElement @Getter @Setter private LocalDateTime javaLocalDateTime;
    
}

// COULD BE PART OF CORE

public final class JaxbAdapters {

    
    public static final class LocalDateAdapter extends XmlAdapter<String, LocalDate>{

        public LocalDate unmarshal(String v) throws Exception {
            return LocalDate.parse(v);
        }

        public String marshal(LocalDate v) throws Exception {
            return v.toString();
        }

    }
    
    public static final class LocalDateTimeAdapter extends XmlAdapter<String, LocalDateTime>{

        public LocalDateTime unmarshal(String v) throws Exception {
            return LocalDateTime.parse(v);
        }

        public String marshal(LocalDateTime v) throws Exception {
            return v.toString();
        }

    }

   ...
