Answer 1

Usually, you will take a framework like GWT, Echo2 or similar.

The advantage of this approach is that the application feels much more like a desktop app. When the server is fast enough, users won't notice the many little data packets that go back and forth. Also, loading a page from scratch is an expensive operation. If you just modify parts of it, the browser can keep a lot of the existing model in memory and just change the parts that changed.

Another advantage of these frameworks is that you can develop your application in pure Java. This means you can debug it in your IDE just like any other Java app, you can write unit tests and run them automatically, etc.
