[Nusoap-general] Can't make example run

[freex f. <fr...@gm...>]

Hi to all, i really wanted to use this tool NUSOAP so what I did is to look
for an Tutorial
I found one http://www.scottnichol.com/nusoapintro.htm. and I quickly
downloaded the
NUSOAP package at sourceforge.

I immediately encode the sample code for the server and client from the sai=
d
site (http://www.scottnichol.com/nusoapintro.htm )but when I
try to run the client. I got this error:

*Warning*: SoapClient::__construct(
http://localhost/freex/soap/s1/soap-server.php)
