Missing MessageBodyWriter for XML

[tadrian]

I am trying to return XML instead of the JSON from a map or a list but I get error. below is a changed version of the DominoObjectsSample class in example db

@Path("dominoObjects")
public class DominoObjectsSample {
	@Inject
	Database database;
	
	@Inject
	@Named("dominoSession")
	Session session;
	
	@Inject
	@Named("dominoSessionAsSigner")
	Session sessionAsSigner;
	
	@Inject
	@Named("dominoSessionAsSignerWithFullAccess")
	Session sessionAsSignerWithFullAccess;
	
	@Path("/json")
	@GET
	@Produces(MediaType.APPLICATION_JSON)
	public Map<String, Object> getJson() {
		Map<String, Object> result = new HashMap<>();
		result.put("database", toString(database));
		result.put("dominoSession", toString(session));
		result.put("dominoSessionAsSigner", toString(sessionAsSigner));
		result.put("dominoSessionAsSignerWithFullAccess", toString(sessionAsSignerWithFullAccess));
		return result;
	}

	@Path("/xml")
	@GET
	@Produces({ MediaType.APPLICATION_XML, MediaType.TEXT_XML })
	public Map<String, Object> getXml() {
		Map<String, Object> result = new HashMap<>();
		result.put("database", toString(database));
		result.put("dominoSession", toString(session));
		result.put("dominoSessionAsSigner", toString(sessionAsSigner));
		result.put("dominoSessionAsSignerWithFullAccess", toString(sessionAsSignerWithFullAccess));
		return result;
	}
	
	@Path("/xml2")
	@GET
	@Produces({ MediaType.APPLICATION_XML, MediaType.TEXT_XML })
	public List<Person> getXml2() {
		
		List<Person> personList = new ArrayList<Person>();
		personList.add(new Person("A1","A2"));
		personList.add(new Person("b1","b2"));
		return personList;
	}

	private String toString(Object obj) {
		if(obj == null) {
			return "null";
		} else {
			return obj.getClass().getName() + "@" + Integer.toHexString(obj.hashCode());
		}
	}
	
	public class Person{
		
		String firstName = "";
		String lastname = "";
		
		public Person(String firstName, String lastname) {
			super();
			this.firstName = firstName;
			this.lastname = lastname;
		}

		public String getFirstName() {
			return firstName;
		}

		public void setFirstName(String firstName) {
			this.firstName = firstName;
		}

		public String getLastname() {
			return lastname;
		}

		public void setLastname(String lastname) {
			this.lastname = lastname;
		}
		
		
		
	}
}
