Apache Tapestry

Apache Tapestry is an open-source, component-oriented web application framework for Java. It enables developers to build dynamic, scalable, and maintainable web applications by leveraging Java’s strengths and simplifying the development process. Tapestry builds upon the Java Servlet API and works seamlessly in any servlet container or application server.
