[Twisted-Python] Writing onto txWS

[vinod kumar]

Hi All,

   I have run and edited the example provided for txWS. The writing part
from server to client browser is shown only as self.transport.write()
inside dataReceived function in websockets.py. how do I write on to the
socket i.e. on to the browser, from a different function inside server
code(server.tac). I'm just starting another xmlrpc server on a thread where
I receive some notifications. I need to forward the same to socket. The
bold point below  is where I want to write on to socket. How can we do
that? Please help me out.

    def __init__(self):
        self.start_time = time.time()

        ws_server = internet.TCPServer(8077, factory)
        ws_server.setName('ws-tcp')
        ws_server.setServiceParent(application)

    server.serve_forever()
