tapestry 5, ajax, javaee and spring

[Maris Orbidans]

Does tapestry support ajax ?

Have you discussed in your book how to use ajax and tapestry ?

And what about javaee and spring integration ? Can I use @SpringBean and @EJB annotations like in wicket ?

[David O'Meara]

Yes, Tapestry has support for AJAX.

Tapestry 5 relies heavily on annotations to reduce coding and provide additional features, but in some cases it is still possible to 'just write code' if you want.

[Alexander Kolesnikov]

Let me quote the Tapestry website here:

Tapestry includes sophisticated JavaScript and Ajax support, based on the Prototype and Scriptaculous libraries. These libraries are all packaged with Tapestry itself ... no extra download required.

The goal for Tapestry is to have many basic and useful components available within the application itself, and make it easy for other JavaScript widgets to be encapsulated as Tapestry components.

Ajax support takes the form of new components and, occasionally, component mixins.

Mixins are a kind of packaged additional behavior that can be added to different components. An example is Autocompleter.

As for integrating with Spring, there is a separate Tapestry-Spring subproject that makes possible simply injecting Spring artifacts into the page. There is also Tapestry-Hibernate integration library available, and using it is also very easy.

All these features aren't covered in my book though. There is a plan to write two other books - one on Ajax, another on testing and integration.
