v2.1.1, joda module.
I can convert a json file to a pojo in a unit test using objectMapper.readValue(file, pojo .class);
However, when a Spring RESTTemplate client invokes the default json converter to convert an inputStream containing the domain object with Joda types (DateTime or LocalDate), it generates an error: objectMapper.readValue(httpInputMessage.getBody(), javaType)

Same issue occurs with LocalDate
com.fasterxml.jackson.databind.JsonMappingException: Unexpected token (START_OBJECT), expected START_ARRAY: expected JSON Array, String or Number at Source: org.mortbay.jetty.HttpParser$Input@d297c0; line: 1, column: 51 at com.fasterxml.jackson.databind.JsonMappingException.from(JsonMappingException.java:164) at com.fasterxml.jackson.databind.DeserializationContext.wrongTokenException(DeserializationContext.java:692) at com.fasterxml.jackson.datatype.joda.deser.LocalDateDeserializer.deserialize(LocalDateDeserializer.java:50) ....
Why is the call chain passing a START_OBJECT in one case and START_ARRAY in the other?
To solve a similar problem I did the following,
I downloaded jackson-datatype-joda-2.2.1.jar from http://mvnrepository.com/artifact/com.fasterxml.jackson.datatype/jackson-datatype-joda/2.2.1 if you are using maven the dependency definition is there too.
then I added an annotation for every LocalDate field in my app as follows:
@JsonDeserialize(using=LocalDateDeserializer.class)
private LocalDate releasedDate;
the imports look like this:
import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.datatype.joda.deser.LocalDateDeserializer;
And the problem vanished.
Hope this helps!
