"""connect(address)
Connect to a remote socket at address. (The format of address
depends on the address family -- see above.) Note: This method has
historically accepted a pair of parameters for AF_INET addresses instead
of only a tuple. This was never intentional and is no longer available
in Python 2.0 and later. """
So if Jython 2.1 is conformant it should indeed require a single
argument which is an (IPAddress, port) tuple.
It might be that the OP can't, for some reason associate with the local
environment, resolve "localhost" to an IP address. What happens if
"127.0.0.1" is substituted?
Irrespective of that, it does seem that the error message is at best
misleading and at most just plain wrong. There's aproject to bring
Jython up to a more recent specification, but it will take time ...
