xmlrpclib fault 8002

[SONAL ...]

I Sonal Dolas work on python for project.
We connect to server as follows:
*self.server = xmlrpclib.Server("http://localhost:7081", allow_none=True)*

I get following errror when the particular file is run:

 * File "/usr/lib/python2.6/xmlrpclib.py", line 1199, in __call__*
*    return self.__send(self.__name, args)*
*  File "/usr/lib/python2.6/xmlrpclib.py", line 1489, in __request*
*    verbose=self.__verbose*
*  File "/usr/lib/python2.6/xmlrpclib.py", line 1253, in request*
*    return self._parse_response(h.getfile(), sock)*
*  File "/usr/lib/python2.6/xmlrpclib.py", line 1392, in _parse_response*
*    return u.close()*
*  File "/usr/lib/python2.6/xmlrpclib.py", line 838, in close*
*    raise Fault(**self._stack[0])*
*xmlrpclib.Fault: <Fault 8002: 'error'>*
