There are lots of ways to get your hands on WAS Liberty. Note that you will need a version of Liberty that has support for JAX-RS 2.0, CDI 1.2, EJB Lite 3.2, and Concurrency Utilities for this sample (Java EE 7 Web Profile will do).
To download just the WAS Liberty runtime, go to the wasdev.net Downloads page, and choose between the latest version of the runtime or the latest beta. You can also download Liberty via Eclipse and WDT
There are a few options to choose from (especially for the beta drivers). Choose the one that is most appropriate.
- There are convenience archives for downloading pre-defined content groupings
- You can add additional features from the repository using the installUtility or the maven/Gradle plugins.
- If you use bash, consider trying the command line tools, which provide tab-completion for the server and other commands.
