This workshop traverses the new features in Jakarta EE 9 by introducing the Cargo Tracker application. This end-to-end example is a new project at the Eclipse Foundation and aligned with Jakarta EE. Cargo Tracker brings back some of the ideas of the Java EE Blue Prints efforts of years past. Some of the new Jakarta EE 9 features demonstrated in Cargo Tracker include SSE, Jakarta Security, asynchronous event observers, repeatable annotations, and the Date-Time API. This is your chance to look at Jakarta EE 9 features in the context of a realistic application, available with an MIT license.
