I was able to get the answer to this from the Jackson user mailing list, and wanted to share with you since it is a newbie issue. From reading the Jackson Date FAQ, I did not realize that extra dependencies and registration are required, but that is the case. It is documented at the git hub project page here https://github.com/FasterXML/jackson-datatype-joda
Essentially, I had to add another dependency to a Jackson jar specific to the Joda data type, and then I had to register the use of that module on the object mapper. The code snippets are below.
For my Jackson Joda data type Maven dependency setup I used this:
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-joda</artifactId>
<version>${jackson.version}</version>
</dependency>
To register the Joda serialization/deserialization feature I used this:
ObjectMapper objectMapper = new ObjectMapper();
objectMapper.registerModule(new JodaModule());
objectMapper.configure(com.fasterxml.jackson.databind.SerializationFeature.
WRITE_DATES_AS_TIMESTAMPS , false);
