Well, I would have expected to see the fault in $answer->{Fault}, but
$answer is undef.

I *like* reporting faultstrings, but that depends on being returned
them :-)

This is how my call looks like.  $answer is undef, so I look at $trace.

Didn't know about $trace->error, but it's not enlightening me much more,
as I already knew that it's unhappy about decoding, but can't see a reason
why this is so...

error: decode error: cannot find element or attribute `{http://xml.apache.org/axis/}hostname'

... and neither is $trace->printErrors ...

Errors while decoding:
  error: decode error: cannot find element or attribute `{http://xml.apache.org/axis/}hostname'


My application uses $answer->{Fault}->{faultstring} to report specifically
what went wrong, and that normally *works* - here it doesn't, and I try
to find out why.  "Just give up if $answer is empty or $trace->errors is
set" is not good enough, as different faultstrings need to be handled 
differently - there's certain faultcodes in the application that warrant
re-trying a few minutes later, and others are "fatal" (like this one),
but should still be reported.


Pointing at the SOAP Response again:

<?xml version="1.0" encoding="utf-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><soapenv:Fault><faultcode xmlns:ns1="http://www.telefoncia.de/kts">ns1:10002</faultcode><faultstring>ARERR [10002] Could not transmit data to TDe (See Error Queue for detailed information). (User \'XXXXX\' not found)</faultstring><detail><ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">solr-663</ns2:hostname></detail></soapenv:Fault></soapenv:Body></soapenv:Envelope>

... there is a "<hostname>" inside here, and it seems to have the right
namespace as well, so why is it erroring?
