A Simple example of how to create a DBUS service.

[sathishkumar sivagurunathan]

Thanks Leonel for the answer,

As mentioned, I followed the exact procedure.

As a first step, I created an app that needs to be called, compiled it and
the moved the executable file ComMain.out to the exec folder.

The ComMain.out was made executable using chmod +x ComMain.out.

I created the service file and moved it usr/share/dbus-1.0/services folder.

The service files is listed below.. The file is named as
org.pulseaudio.genivi.RoutingSender.service.

# DBus service activation config
[D-BUS Service]
Name=org.pulseaudio.genivi.RoutingSender
Exec=/usr/bin/genivi/ComMain.out

Then using the dbus send command, I invoke the dbus

dbus-send --dest='org.pulseaudio.genivi'        \
            /org/pulseaudio/genivi/RoutingSender              \
            org.pulseaudio.genivi.RoutingSender   \
            int32:47

But I am not able to receive the desired result..

1) I am not able see the bus name when I invoke a "QDBUS" command on the
terminal..
2) I have tried to create a file in my program. When my program is invoked,
no file is generated in the folder..

I tried to restart the system to check incase the dbus daemon is not
picking my service.

Am I doing something wrong. Is there any way to check what I am doing wrong
??

Thanks,
Sathish..
