At a Glance
You will learn how to build an application with multiple modules with Maven and Open Liberty.
A Jakarta Platform, Enterprise Edition (Jakarta EE) application consists of modules that work together as one entity. An enterprise archive (EAR) is a wrapper for a Jakarta EE application, which consists of web archive (WAR) and Java archive (JAR) files. To deploy or distribute the Jakarta EE application into new environments, all the modules and resources must first be packaged into an EAR file.
You will build a unit converter application that converts heights from centimeters into feet and inches. The application will request the user to enter a height value in centimeters. Then, the application processes the input by using functions that are found in the JAR file to return the height value in imperial units.
