Starting at the very infancy of software creation, developers tried to modularize their applications in order to streamline their projects and increase the maintainability of the software they created. Soon, a very basic segregation scheme was identified: One part of the software must deal with data and persistence, another part must deal with presenting the data to the user, and one last part must handle data input and frontend view propagation. This segregation scheme showed up in so many projects that it was promoted to a common software design pattern, called Model-View-Controller, or MVC for short. Its power also manifested in its versatility, even with big paradigm changes, like the onset of the Internet age. With database products for the model layer, browsers for the view layer, and some kind of user input processing for the controller layer, the pattern’s accuracy and applicability to the majority of software projects became even more apparent with web applications. Interestingly, even though most web application frameworks under the hood apply some kind of MVC layer demarcation, Java Server products up to JEE 7 did not include a dedicated MVC framework. With JSR-371 (Java Specification Request number 371) only recently and starting with JEE 8/Jakarta EE 8, an MVC specification entered the Java Enterprise application realm, which is one of the reasons this book was born. It does not describe all MVC Frameworks that you can add to Java EE/Jakarta EE as an external library. There are just too many of them and you can learn about them by looking at each library’s documentation. Instead, we talk about the genuine Java MVC library as described by JSR-371. The target version of Java MVC is 1.0, and we use a Jakarta EE version 8.0 compliant server to run Java MVC on it.
