Configuring Java

Java provides a robust, enterprise-grade language for the development of all kinds of applications. To build Java applications from source, you need a Java Software Development Kit (Java SDK). To run Java applications, which are compiled into Java Archives (*.jar, *.war, *.ear), you need a Java Runtime Environment (JRE).

There are many options for Java. We recommend IBM’s Java SDK.

Configuring Maven

Apache Maven is a build tool that is very popular for Java applications. You can download and configure Maven from Apache’s website.

Configuring Docker

The examples in this book use Docker to create Open Container Initiative (OCI)-compatible images. Docker runs OCI-compliant images and provides an easy-to-use API and tools for working with these images. You can configure Docker for your platform from Docker’s website.
