I'm trying to create a taskbar app (in wxpython) to monitor job progress on a render farm. I'd like the taskbar app to have an xmlrpc server built in so that other applications can inform the taskbar app additional jobs to monitor. I found this recipe online which is a great example of the functionality I want: http://code.activestate.com/recipes/298985/ However when I run the following from xmlrpclib import * s = ServerProxy('http://localhost:7080') # Get access to xmlrpc server s.title('Hallo xmlrpc app') I don't get a response (though the title in the window changes - so I know it got it) I do get this though: Traceback (most recent call last): File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\protocols\basic.py", line 239, in dataReceived return self.rawDataReceived(data) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\http.py", line 1117, in rawDataReceived self.allContentReceived() File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\http.py", line 1108, in allContentReceived req.requestReceived(command, path, version) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\http.py", line 626, in requestReceived self.process() --- <exception caught here> --- File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\server.py", line 150, in process self.render(resrc) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\server.py", line 157, in render body = resrc.render(self) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\resource.py", line 189, in render return m(request) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\xmlrpc.py", line 122, in render_POST function = self._getFunction(functionPath) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\xmlrpc.py", line 170, in _getFunction handler = self.getSubHandler(prefix) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\xmlrpc.py", line 107, in getSubHandler return self.subHandlers.get(prefix, None) exceptions.AttributeError: 'MyXMLRPCApp' object has no attribute 'subHandlers' Unhandled error in Deferred: Traceback (most recent call last): File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\resource.py", line 189, in render return m(request) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\xmlrpc.py", line 126, in render_POST defer.maybeDeferred(function, *args).addErrback( File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\internet\defer.py", line 195, in addCallback callbackKeywords=kw) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\internet\defer.py", line 186, in addCallbacks self._runCallbacks() --- <exception caught here> --- File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\internet\defer.py", line 328, in _runCallbacks self.result = callback(self.result, *args, **kw) File "d:\toolkit\sww\win32\python\2.4\lib\site-packages\twisted-8.1.0-py2.4-win32.egg\twisted\web\xmlrpc.py", line 144, in _cbRender allow_none=self.allowNone) exceptions.AttributeError: 'MyXMLRPCApp' object has no attribute 'allowNone' I'm assuming this is just a good example that is out of date. However I'm not sure how to update it so that it works. Can someone help me out?
