As openhab2 doesn’t have a binding for mpd currently - what is the best alternative to use for online radios?
As a suggestion, try out the OH1 mpd binding if it works under OH2 (see http://docs.openhab.org/developers/development/compatibilitylayer.html for this)
If it turns out, that the binding works under OH2, too, this binding could be marked as compatible.
If this doesn’t work, and you’re able to setup a server, you could use the squeezebox binding. there is squeezelite as a software player, and the logitechmediaserver to communicate with openhab, deliver netstreams and music (both free to use, both for windows or linux available)
I was able to get this binding working in OH2.
The initial attempt failed with the error below, but I was able to work around it by dropping a 1.9.0 copy of the binding into the addons directory.
With that jar, it appears the start/stop/next/volume commands all work fine…

Can you tell me where I can find the jar file of the 1.9.0 MPD Binding?
Thanks a lot!
I can’t get the jar file from this place.Could you upload working file, please. I have the same exception as you mentioned above.
Unfortunately, I still have the same exception below.
I added MPD server config in …\services\mpd.cfg
mpd:server.host=192.168.1.131
mpd:server.port=6600
Do I need some other configurations to make it work properly?

What does your item binding look like?
Very simple binding
Switch Mpd_StartStop “Start/Stop” { mpd=“ON:server:play, OFF:server:stop” }
MPD works well. I can control it using mpc from command line.
Very strange. Can you provide a full debug log?
Here is the full log after one action. I have no idea how to debug the problem.

I’ve tried DEBUG level of logging. I didn’t see new error messages. But I found the error while updating mpd.cfg. That is the main problem, mpd configurations are not read. I’ve tried different combinations - nothing. Can you show me your mpd.cfg ?

@1117 I would try the following:
Make sure that you have installed (via console): feature:install openhab-runtime-compat1x
Drop the latest *.jar in your ..\addons\ folder
change ..\conf\services\mpd.cfg to:
server.host=192.168.1.131
server.port=6600
set log level to DEBUG for the MPD Binding: log:set DEBUG org.openhab.binding.mpd
check logs and reply 
Done as you told. Openhab startup log with the problem in bold is listed below. I cheсked mpd.cfg many times.

Maybe: delete the mpd.cfg
recreate it without using notepad (use another text editor), Type the text, don’t copy-paste.
There may be some kind of character (or new line feed) that stops the binding from parsing properly the config data.
Nothing. I am using nano editor. It looks like very simple mistake. Ok, thank you. I will try to find.
Finally It works! Openhab was reinstalled from the scratch.
feature:install openhab-runtime-compat1x is very important!
