Not getting values

object DQJsonHandler{
  implicit val formats = DefaultFormats
  val dqjson = """{

    def main(args: Array[String]): Unit = {

    val json = parse(dqjson)
    println(json)


      val entityelements = (json \\ "entitytype").children
      println(entityelements)
      for ( element <- entityelements ) {

        val e = element.extract[EntityType]
        println(e.entityURI.toString)
      }


  }
}

Below is the output as None

JObject(List(JField(DQMap,JArray(List(JObject(List(JField(entitytype,JObject(List(JField(entityURI,JString(MedicinalProduct))))))))))))
List(JField(entityURI,JString(MedicinalProduct)))
-------JField(entityURI,JString(MedicinalProduct))
None

You'll note `entity` here is a JField; JField's can't be extracted directly. You want to

extract the field's value:

for (JField(_, element) <- entityelements) {

  val e = element.extract[EntityType]

}

Give that a shot, I think it should work.

Thanks,

Antonio
