summary
Compares three concrete stacks: JSF (server-side XHTML + PrimeFaces, good for server-rendered HTML for SEO, limited dynamic partial updates), j2cl (compiles Java to browser JS, used to ship a working Tetris game; requires Bazel, loses reflection and many JVM libraries — not JVM-compatible), and Vaadin (Java runs on the JVM, rich component set, live demo sandbox works, needs memory and sticky sessions for scaling but gives the smoothest Java developer experience).
