I was using a servlet mapping to make my url nicer. Instead of appid.appspot.com/MyApp.jsp, I had appid.appspot.com/servletname. And I was using the jsp-file tag to map the servlet to the jsp file.
I have commented out the servlet definition and just let the jsp auto mapping do its thing. And everything works fine, albeit with uglier urls. Btw, I'm using a jsp for my GWT host file instead of an html file so that I can secure the app host file. Html being statically deployed makes it impossible to secure at the servlet layer. R.
