I have tried to configure the URLs in my DispatcherServlet to map to URLs without an extension. I finally figured this out, but I don't understand why the URL is working out the way it is.
Assuming a context of 'foobar'... if the url-pattern for the DispatcherServlet is /rest/* and I have a RequestMapping of /rest/js, then in order to get to the page, I have to go to hostname:port/foobar/rest/rest/js . Why does the URL have a double /rest/rest on it?
This doesn't make sense, because if I have multiple DispatcherServlets, couldn't the same RequestMapping go to different URLs? i.e. if the RequestMapping is '/js', and I have a DispatcherServlet set to go to /rest/* and another set to /json/*, then wouldn't hostname:port/foobar/rest/js and hostname:port/foobar/json/js return the same page?
I can't get the URL to come up at all if the @RequestMapping is on the class definition - it only works on the method.
