Java EE 7 Hands-on Lab has been delivered all around the world and is a pretty standard application that shows design patterns and anti-patterns for a typical Java EE 7 application. It shows how the following technologies can be used in a close-to-real-world application:
WebSocket 1.0
JSON Processing 1.0
Batch 1.0
Contexts & Dependency Injection 1.1
Java Message Service 2.0
Java API for RESTFul Services 2.0
Java Persistence API 2.0
Enterprise JavaBeans 3.1
JavaSever Faces 2.2
However the lab requires you to download NetBeans (Java EE 7 tooling) and WildFly or GlassFish (Java EE 7 runtime).
If you don’t want to follow the instructions and create the app, a pre-built solution zip file is available. But this still requires you to download Maven and build the app. You still have to download the runtime, which is pretty straight forward for WildFly, but still an extra task.
Maven step can be reduced using a pre-built WAR file, but runtime is still required.
Docker containers allows you to simplify application delivery by packaging all the key components together in an image. So how do you get the first feel of Java EE 7 hands-on lab with Docker ?
If you are new to Docker, Tech Tip #39 provide more background and details on how to get started. After initial setup, you can pull the Docker image that contains WildFly and pre-built Java EE 7 hands-on lab WAR file as shown:
And then you can run it as:
Find out the IP address where your container is hosted using boot2docker ip command. And now access your Java EE 7 application at http://<IP>/movieplex7. The app would look like:
Here is the complete log shown by the Docker container:
Source code for this Dockerfile is pretty straight forward and at github.com/arun-gupta/docker-images/blob/master/javaee7-hol/Dockerfile.
Enjoy!
