We still have some JAXB related code within the consumer, so I'm going to go ahead and clean up that code so we can focus on the JsonParser. So once we've cleaned things up, we can go ahead and create a parser, and we're going to do so within a try block. The JsonParser implements the AutoCloseable interface, so that once we're finished with the parser, we can be sure that the resources will be cleaned up. So once we create a JsonParser object, all we need to do is use the Json object and invoke its createParser method. The JsonParser method will accept a reader. So we're going to go ahead and use a StringReader, and we'll pass in the json that we receive from the Jms…
