Workflows with Java EE

The demonstrated examples cover general Java build piplines which are, of course, applicable to Java EE as well. In fact, using Java Enterprise highly supports productive development pipelines. Fast builds and therefore fast developer feedback is crucial to effective Continuous Delivery workflows.

Zero-dependency applications, especially when packaged in containers, leverage these principles as we have seen in Chapter 4, Lightweight Java EE. The enterprise application in the packaged artifact or the container layer, respectively, only contains the business logic that was developed against the API. The application container provides the implementation.

The Continuous Delivery pipeline benefits from zero-dependency applications, since the involved build and distribution steps only require short execution and transmission times, respectively. Artifact builds as well as container builds run as fast as they can get, with only copying what's absolutely necessary. In the same...
