I have tried to get working code of chapter 11 and when a toetem client clicks on wait button no iq arrives to referee. I have proved with code in git and modifying it to using my own local ejabberd server, and the problem is the same, I recieve in the toetem client an iq with error code 503, type "cancel" and service-unavailable.

I think that the server complains with the namespace "http://metajack.im/ns/toetem".

How can I solve this?

Thank you.

My guess is that you are setting the JID to a bare JID instead of a full JID.

Sending an IQ to a bare JID results in the IQ getting handled by the server's session manager, not the destination client.

Ok. Thank you. Now it is working.

Anyway, Do you think that the client must know the full ID of the referee at login time? Each time I execute the referee the resource part of the JID changes; I have dealed with this responding the direct presence of the toetem client with a direct presence from the referee to the client, so it can store the full JID of the referee and use it to send IQ's.

The example program needs to know the full JID at login time, but in a real game server system you would have some way to discover the correct addresses, or the addresses would be well known. Since I don't have control over what addresses you will use to run the program, I wrote it so that you had to know them at login.

It sounds like you are implementing discovery, which is great. I left things like that out to keep it as simple as possible.
