GWT RequestBuilder is based on XmlHttpRequest, which has to honour
same origin policy for security reasons.
I haven't tried this, but technically it should work.
a) Create a FormPanel, and set the action to the URL that you want.
Set the method to "get".
b) Add a SubmitCompleteHandler to the FormPanel, and implement the
onSubmitComplete(SubmitCompleteEvent event) method
c) Use event.getResults() method to get the contents of the URL.
Note that this approach doesn't have the equivalent of onFailure
method. If there is a backend exception, a 404 or any other problem,
you will just get the raw HTML explaining the problem. Any other
approach you adopt will have the same problems though.
