Hi Romain, The model is generated using jaxb from an XSD. Jaxb has been set up to map xs:dateTime to java.time.Instant
getters/setters look like this: public Instant getDate() { return date; } public void setDate(Instant value) { this.date = value; } As the model is generated I don't have the option of adding annotations on it and need to configure Johnzon to globally deal with Instant data type Paul On 14 October 2017 at 09:36, Romain Manni-Bucau <rmannibu...@gmail.com> wrote: > Hi > > What is your model? > > Did you try @JohnzonConverter too? > > Tomee uses an old johnzon too so can need some enhancements from master. > > Le 14 oct. 2017 03:10, "Paul Carter-Brown" <paul.carter-brown@smilecoms. > com> > a écrit : > > > Hi, > > > > I've created an adapter as follows: > > > > public class JavascriptDate implements Adapter<String, Instant> { > > > > @Override > > public String to(Instant instance) { > > final Calendar cal = GregorianCalendar.getInstance(); > > cal.setTime(Date.from(instance)); > > return DatatypeConverter.printDateTime(cal); > > } > > > > @Override > > public Instant from(String text) { > > return DatatypeConverter.parseDateTime(text).getTime(). > > toInstant(); > > } > > } > > > > and register it globally like this in a servlet init: > > > > new MapperBuilder().addAdapter(new JavascriptDate()).build(); > > > > When I call a rest service passing a date formatted string field that > needs > > to map to an Instant I get an error: > > > > org.apache.johnzon.mapper.MapperException: Using fallback converter, > this > > only works in write mode but not in read.
