Hello everybody.
I have realized a cometd connection between a client and a server. Pushing data from server to client over the channel is possible. But how is it possible to send data (JSON) from the client to the server. Is it also possible over the same channnel I used for cometd-connection.

dojox.cometd.subscribe("/ping", sample, "publishHandler");

Have I to define a callback function on the server side? Or doesn't it work and I have to realize it in another way (dojo.io.bind -> who does it work with this)?
I hope anyone can help me...
Thank's
