Google App Engine URL Handling

I have a Java Google App Engine application with one module and one HTML page.

I would like to serve different content to the user, using GWT, by using different URLs.

For example:

"http://myapp.appspot.com/" Serves the main HTML page and calls the entry point method. This works fine.

I would like to serve different UI content when I use a browse to a URL like "http://myapp.appspot.com/differentcontent/".

I know I can set up a servlet in WEB.XML and create a serv开发者_如何学JAVAer side class for that URL pattern, but how do I get back to a GWT client side class from the servlet class when the servlet call did not originate from GWT? Any help would be much appreciated!

You can use the History (docs) but your url instead of being http://myapp.appspot.com/differentcontent/ will be http://myapp.appspot.com/#differentcontent.
