Google Web Toolkit - Build AJAX apps in the Java language
released on 5/16/2006

It seems powerful and slick
Had a quick look at it.
It is a small but complete framework. Everything is written in Java,
even the GUI components, which are compiled into Javascript+HTML. There
is a remote procedure call interface that allows arbitrary serializable
java objects to be sent to the client, even exceptions. I can't say much
on the Java to Javascript+HTML compiler, but it doesn't seem to be such
a good idea. Java 1.5 is not supported, and the rich set of java
libraries can't be used.
It's certainly an intriguing idea (have a look at haxe.org if you find
it interesting), but I don't really believe in this concept. It is very
difficult to abstrahize the features (or should I say quirks) of
different browsers. Some months ago, I had a look at several javascript
libraries and it worked pretty flawless in every browser. When I checked
again this week, one browser simply crashed. On 2 of 4 pages. It's sad,
but it's just not stable enough for me. The GWT demo site worked fine,
but custom components will be very tedious to develop and maintain.
Another issue is previewability. Not just for a designer, but for
debugging purposes. If you click "view source" in your browser on a GWT
page, you will see nothing but a HTML skeleton and an iframe.
Anybody has any idea to integrate it to wicket ?
Integration into wicket doesn't seem feasible to me. It might be
possible to integrate GWT widgets into a wicket page, but I think it
makes more sense to use wicket components in combination with a client
side ui library like the yahoo ui library. The effect will be the same,
but you only have one type of component to take care of. But I don't
know if wickets AJAX support is good enough yet.
