Challenge
- [Instructor] Okay let's have a look at a challenge that will help you understand better how to use the JMS, and in particular how to use the observer. The challenge is, implement a view for observed cargo events. So the first thing you need to do is to implement an observer that listens for cargo events. Then when it receives a cargo event, it will need to add it to a collection. And then write a view that displays the handled cargos in a data table. And a little hint: have a look at the onCargoInspected method in the RealtimeCargoTrackingService class. This challenge shouldn't take more than about 10 minutes.
