Activation

[Luigi Paioro]

Hello!

I think I've not understood well how .service files work.

I've created a server script (HelloTestServer.py) which provides a 
simple object:

<code>

#!/usr/bin/python

import gobject
import dbus
import dbus.service
import dbus.mainloop.glib

class HelloWorldObject(dbus.service.Object):
     def __init__(self, bus_name, 
object_path='/org/freedesktop/HelloWorld'):
         dbus.service.Object.__init__(self, bus_name, object_path)

     @dbus.service.method('org.freedesktop.HelloWorldIFace')
     def hello(self):
         print "Hello world!"

dbus.mainloop.glib.DBusGMainLoop(set_as_default=True)
session_bus = dbus.SessionBus()
bus_name = dbus.service.BusName('org.freedesktop.HelloWorld', 
bus=session_bus)
object = HelloWorldObject(bus_name)

mainloop = gobject.MainLoop()
mainloop.run()

</code>

So I've created under <prefix>/share/dbus-1/services (I've got a custom 
D-Bus installation) the file hello.service:

<code>

[D-BUS Service]
Names=org.freedesktop.HelloWorld
Exec=<where_is_my_program>/HelloTestServer.py

</code>

Then I've started my D-Bus session:

csh > dbus-launch --csh-syntax
csh > setenv DBUS_SESSION_BUS_ADDRESS 
'unix:abstract=/tmp/dbus-mcynDScyts,guid=5ff550ed59db81f96327200045acff2e';


And then I've tried to connect to my object:

csh > python

 >>> o = session_bus.get_object('org.freedesktop.HelloWorld', 
'/org/freedesktop/HelloWorld')
 >>> i=dbus.Interface(o, 'org.freedesktop.HelloWorldIFace')
 >>> i.hello()

self._connection.send_message_with_reply_and_block(message, timeout)
dbus.DBusException: org.freedesktop.DBus.Error.ServiceUnknown: The name 
org.freedesktop.HelloWorld was not provided by any .service files


My configuration:

dbus-1.0.2
dbus-glib-0.72
dbus-python-0.79.93


Please, can you explain me one more time how can I configure the D-Bus 
activation?

Thank you very much.
