I'm trying to use Jackson to serialize and deserialize objects (marshall/unmarshall) from and to JSON. Some of these objects have Java 8 LocalDate and ZonedDateTime. I've read here that the best option is to use jackson-datatype-jsr310
serialize/deserialize java 8 java.time with Jackson JSON mapper
However, when I try to use this:
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
I get this error:
java.lang.IllegalAccessError: tried to access method com.fasterxml.jackson.databind.ser.std.StdSerializer.<init>(Ljava/lang/Class;)V from class com.fasterxml.jackson.datatype.jsr310.JavaTimeModule
Any clue? I'm using Jackson 2.6.0, jackson-datatype-jsr310 2.6.0 and am deploying to Tomcat 8.
Thanks and best regards

This short tutorial shows how the Jackson library can be used to serialize Java object to XML and deserialize them back to objects.
Jackson by default uses the getters for serializing and setters for deserializing.
Jackson actually doesn't need classes to implement Serializable but I'm going to add it anyway. Writing about a serialization framework and not implementing Serializable might seem strange.
It's important to note that Jackson will serialize the Date to a timestamp format by default (number of milliseconds since January 1st, 1970, UTC).
In the end, the problem was I had a different version of Jackson, due to a dependency with Jongo. jackson-datatype-jsr310 2.6.0 needs Jackson 2.6.0 and Jackson 2.4.1 was being deployed.
