What is Apache Wicket?

Apache Wicket is a component-based web application framework written in Java. It provides a simple and elegant way to create dynamic web applications with reusable UI components. Wicket emphasizes the use of plain Java objects (POJOs) and HTML markup for building web pages, which promotes separation of concerns and testability. It's commonly used for developing complex web applications where maintainability, scalability, and testability are important.
