GWT with JSP to avoid need for AJAX

I have used GWT with AJAX when I need an interactive app. However, in some cases I don't need the app to communicate with the server after the page is initially displayed. For instance, I have a page where I'd like to display a collapsible tree. Normally I'd either have to output javascript in a JSP or I'd have to use GWT with a web service.

Is there any way to use GWT without a web service? For instance, instead of an HTML template, GWT would use a JSP that would populate data in the collapsible tree when the page is initially displayed.

I dont know GWT enough, but GWTs tree widget would definitely have options to store data in the client (Trust Google :) ). Check the doc for the tree widget for stuff like client side cachign etc. I have used similar libraries like Common Controls etc, where you have an option to cache the entire tree hierarchy in the client side or atleast parts of it.

Yes, you can use it with servlets since GWT provides a basic RPC framework for making calls to the server.

girionis, thanks for replying, but I meant that I wanted to use GWT without calling the server at all after the initial display of the page.
