Jackson can only deserializer `java.io.File` instance from JSON String value, so trying to bind from JSON Object will not work. In this case a compatible Java object would look more like: public class FileContainer { public File path; } so that property "path" would have value from which `java.io.File` can be deserialized. -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
