wtf is simplepurewebapp?

This project, called simplepurewebapp, is a minimal example of how to build a website using only Java's built-in tools, without relying on any popular add-on frameworks. It's essentially a learning reference showing the most fundamental way to create web pages and handle user requests in plain Java. At a high level, the project uses two core pieces of traditional Java web technology: servlets and JSPs. A servlet is a small Java program that runs on a server and responds when a user visits a web page, like handling a form submission or a button click. JSP (JavaServer Pages) is a way to build the actual HTML page the user sees, letting you mix standard web markup with Java logic. Together, these have been part of Java's standard toolkit for decades. This kind of project is aimed at beginners learning Java, students in a web programming course, or anyone curious about what happens under the hood before modern frameworks were invented. A teacher might use it as a classroom example, or a self-taught developer might build on it to understand the basics before moving on to more complex tools. The project is notably stripped-down by design. Most modern Java web projects start with heavy frameworks that handle routing, database connections, and user interfaces automatically. This one deliberately avoids all of that, which makes it lightweight and easy to study, but also means you'd have to build many common features from scratch if you wanted to turn it into a real production application. The README doesn't go into detail beyond noting that it uses only servlets and JSP, so the code itself is the primary source of information.
