I don't know the answer, but in general, for this sort of issue, you need to figure out which URL the request is being sent to from the browser, and whether that URL is correct. (In particular, is it the same URL with JDK 6?) The Chrome or Firefox debugging tools are useful for this; it's the "Network" tab in Chrome.
If the URL hasn't changed then there might be a problem on the server side.
