I have simplest hello-world application. It is correctly if it is run locally. But the app show an error on Heroku. The error is "Failed to load resource: https://vast-harbor-19423.herokuapp.com/favicon.ico the server responded with a status of 503 (Service Unavailable)"

This is python code:

import tornado.ioloop
import tornado.web
import tornado.websocket

class Hello(tornado.websocket.WebSocketHandler):
    def open(self):
        self.write_message("Hello, world")

    def on_message(self, message):
        pass

    def on_close(self):
        pass

class Main(tornado.web.RequestHandler):        
    def get(self):
        self.render("hello.html")

application = tornado.web.Application([
    (r"/", Main),
    (r"/websocket", Hello),
])

if __name__ == "__main__":
    application.listen(8888)
    tornado.ioloop.IOLoop.instance().start()

This is hello.html:

<!DOCTYPE html>
<html>
<head>
    <title>Tornado Hello</title>    
</head>
<body>
 <h1>Hello World from Tornado</h1>
 <script>
 ws = new WebSocket("ws://vast-harbor-19423.herokuapp.com/websocket");
 ws.onmessage = function(e) {
    alert('message received: ' + e.data);
 };
 </script>
</body>
</html>

How can I solve the problem?

There is the favicon.ico file in the root of the app folder.

I'm not sure where this 503 is coming from - could it be coming from heroku? There may be a favicon.ico file in the app folder, but you haven't told tornado to do anything with that file. A request for /favicon.ico on this tornado server will result in a 404, not a 503. You need to set static_path in the Application constructor to serve static files like favicon.ico.

Thank you, Ben! It works. I added static_path var, static folder and moved favicon in the folder.

I am creating a GWT project from the GWT Material official website using maven. I am following the tutorial offered by the site. Im getting this in the view page:

HTTP ERROR: 503
Problem accessing /index.html. Reason:
Service Unavailable
Powered by Jetty://

I tried all the solution proposed here but I failed to view the project homepage.

There is no error in the eclipse console. but when inspecting the home page im getting this error:

Voice Instead ready.
content.js:29 Object
favicon.ico Failed to load resource: the server responded with a status of 503 (Service Unavailable)

Hi Marwen,

It looks like you've found the wrong forum. This one is about the Tornado web framework; you need a forum about GWT and/or Jetty.
