Hi All

I have a doubt about how to factor the an xmlrpc server code. Basicly what happens is:

def xmlrpc_runCmd(self, hostname, command): # I call a method that returns a deferred and because of that I # don't have anything to return to the xmlrpc client. runComm = conn.runCommand(hostname, command) # the line below doesn't make much sense because the output needs to # return to the xmlrpc client runComm.addCallback(self.printOutput)

return ???? # return what?!?!?!?

What should I do? How should I factor the code?

As JP told you, you should return the deferred 'runComm' without adding the callback 'self.printOutput'. The method render of XMLRPC automatically add the '_cbRender' callback which does the job, and return the code 'NOT_DONE_YET' which makes you client wait.
