This sample project demonstrates that writing (and testing) a JCA resource adapter is fairly easy. We implemented a Message Driven Bean which observes a certain directory for files which are created, updated or deleted.
It's tested using:
- Arquillian - powerful testing middleware
- Awaitility - simple, yet powerful DSL that allows you to express expectations of an asynchronous system in a concise and easy to read manner
This sample project is based on Robert Panzer work (read the full blog post by Robert here).
