Is it possible to develop an application in groovy using GWT components?

回答1:
If you want to use Groovy on the server-side and GWT for the UI, that is certainly possible. You can use Grails (a Groovy web framework on the server), and the Grails GWT plugin to help you integrate GWT with this framework.
回答2:
I don't think so, because the GWT compiler is basically a Java to JavaScript source compiler (it would be possible if the GWT compiler needed Java bytecode). You can use Groovy on the server side though.
回答3:
Right now you cant use Groovy on the client side. One big reason is that Groovy relies a lot on introspection, and this is not available on GWT.

I have also wondered this, as it would be very nice. Vaadin essentially does this and you can use their plugin: http://grails.org/plugin/vaadin
Doing it this model, though, it is compiling components into Javascript and delivering from the server. But unlike GWT components, these are calling back to the server every time you touch the API (though of course with Vaadin you can use GWT components as well).
