Cherrypy returning NotFound: (404, "The path '/' was not found.")

Question

I am new to cherrypy and am trying to mount a simple hello world application but it keeps returning "NotFound: (404, "The path '/' was not found.")", but I have defined it.

Here's what I got,

In the __init__.py

import cherrypy
from HomeNetMain import HomeNetMain

cherrypy.config.update("global.cfg")
#I have tried "" for the script name parm but that doesn't work
cherrypy.tree.mount(HomeNetMain,"/","main.cfg") 
cherrypy.engine.start()
cherrypy.quickstart()

In another file I have

import cherrypy

class HomeNetMain:

    @cherrypy.expose
    def index(self):
       return "Hello World"

I have tried with both the decorator and index.exposed=True to no avail (sub question what is the preferred method for cherrypy the decorator or index.exposed)

global.cfg

[global]
server.socket_host: "127.0.0.1"
server.socket_port: 9080
log.screen: True
log.error_file: "/tmp/cherrypy.error"
log.access_file: "/tmp/cherrypy.access"

main.cfg

[/]
log.screen: True
log.error_file: "/tmp/homenet.error"
log.access_file: "/tmp/homenet.access"

I appreciate any help, thanks in advance.

Turns out I shouldn't have been using cherrypy.quickstart() I changed the code to the following and it worked fine

cherrypy.engine.start()
cherrypy.engine.block()
