Thats correct.

I did not specify the "sympa_url", so it actually was talking to the 
webinterface, hence you are correct, too.

BUT, when I tried to find the reason of my problem (before I wrote my 
emails), 
I searched every log file, I searched all the SOAP traffic from and to 
server/client, I hooked myself into the the ports to see what is 
actually happening but there was never any error message from the sympa 
soap interface that there maybe something WRONG.

I think this is a small problem (small bug)?
Looking at the perl code of wwsympa.fcgi I can see:

<code>
    sub do_wsdl {

        &do_log('info', "do_wsdl ()");
        my $sympawsdl = '/home/sympa/bin/etc/sympa.wsdl';

        unless (-r $sympawsdl){
            &error_message('404');
            &wwslog('err','could not find $sympawsdl');
            return undef;
        }

        my $soap_url= &Conf::get_robot_conf($robot,'soap_url');

        # added by me to show a problem ###########
        # 
        my $jobst_msg = "SOAP URL IS $soap_url";
        &do_log('info', $jobst_msg );
        #
        # finished adding by me ###################

        unless (defined $soap_url) {
            &error_message('no_soap_service');
            &wwslog('err','No SOAP service was defined in sympa.conf 
(soap_url parameter)');
            return undef;
        }
</code>

Searching all the log files I have never been able to see the "SOAP service" 
error message. This message should show up (as it is fatal) even if debug 
logging is disabled or set to a normal level (log_level 0).

All I ever see in the logs (amongst other messages is:

    Jun 17 21:13:56 lists.barrett.com.au wwsympa[18488]: do_wsdl () 

but nothing else. If the errormessage

    "No SOAP service was defined in sympa.conf (soap_url parameter)"

would have come up in the log files I would have found the error
straight away without bothering everyone.


My logfile setting is correct (otherwise do_wsdl would not show up):

  syslog  LOCAL1
  log_socket_type unix
  log_level 0

and in syslog.conf:

  local1.* /var/log/sympa



Now using the code from above I deleted the "soap_url" in the sympa.conf file
and restarted sympa and httpd just to be sure ;-), I increased the LOG LEVEL
to 3 in sympa.conf, and this is what I get:

   Jun 19 12:15:30 vps881 wwsympa[18485]: Language::SetLang(cs) 

As expected, my message doesnt SHOW anything, as it is NOT defined .. but
I dont get any othe hint there is something wrong.


Putting the soap_url back into the sympa.conf file I get

   Jun 19 12:20:29 vps881 wwsympa[18849]: List::verify(true()                 
        )

The irritating side-effect of a missing "soap_url" in sympa.conf is that
you get conflicting error messages depending how you call soap client:

  This will yield "transport not found":
  $soapclient = new nusoapclient($soapServer);

  This will yeild "return is not of type xml":
  $soapclient = new nusoapclient($soapServer,'wsdl');

so its really hard to debug!


It would be so easy if the do_wsdl will the admin aware that
"soap_url" is not set!
