SOAP::Lite - Unspecified namespace for type error

freeflyer73 has asked for the wisdom of the Perl Monks concerning the following question:

I am attempting to make a call to a wsdl location at work using soap::lite. I've used it previously without issue but am coming up against and issue this time that i'm struggling to find a solution for.

My calling code is (wsdl location intentionally not included):

use SOAP::Lite 'trace', 'debug';
my $service = SOAP::Lite -> service("http:xxxxxx");
my $xmlCreationResult  = $service -> getLatestPreviewSheetByHouseNumbe
+r('CE_SA_SCOOBD0012_01');

I can see the expected return in the output but the code errors with: Unspecified namespace for type 'audioTrackVO'

I've tried calling the same webservice using C# and it seems to work. I also can't find much existing online that helped.

I am far from an expert on webservices but it looks to me like soap::lite is struggling to parse the result, or is picking up an issue with the result that is not being picked up in C#.

The return begins:

<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
<env:Header>
</env:Header>
<env:Body>
<tns:getLatestPreviewSheetByHouseNumberResponse xmlns:tns='urn:CommonS
+ervice'>
<return xmlns:ns2="urn:CommonService">
<id>51308</id>
<audioTracks xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi
+:type="audioTrackVO">
<id>1390864</id>
<classification>dual mono</classification>
<languageIsoCode>POL</languageIsoCode>
<previewSheetId>51308</previewSheetId>
</audioTracks>

Any suggestions would be appreciated.

Any suggestions would be appreciated. You can see the message comes from inside SOAP::Lite `xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"` associates the prefix xsi with a namespace(url) If you go to http://www.w3.org/2001/XMLSchema-instance you'll find http://www.w3.org/TR/xmlschema-1/#xsi_type So, whatever schema/wsdl/xml is in play doesn't specify what is audioTrackVO -- unknown type is unknown, can't be decoded why this happens? error in the wsdl/xsd or the response or SOAP::Lite? Impossible to know. I'm guessing SOAP::Lite plays a part (needs your help to load schema or somesuch ), but XML is so complicated and 98% of everybody gets it wrong, its hard to say without lots more details (250% more) I suggest you try the latest version cpanp -i PHRED/SOAP-Lite-1.0.tar.gz but that probably won't change anything Better idea is to try SOAP::Simple cpanp -i BERLE/SOAP-Simple-0.00_03.tar.gz, see if SOAP::Simple works for you for this SOAP::Simple is simple :) but its built by something very much SOAP (complex), its XML::Compile::SOAP/XML::Compile::FAQ/https://www.ebi.ac.uk/Tools/webservices/tutorials/06_programming/perl/soap/xml-compile-soap/XML::Compile::SOAP/http://perl.overmeer.net/xml-compile/#doc You might also like How to Call a .NET-based Web Service Using the SOAP::Lite Perl Library, Contact Webservices on Microsoft Exchange Server , An XML Overview Towards Understanding SOAP, it might help you gain a better understanding of SOAP/XML which will help you figure this all out I hate SOAP, really :)	[reply] [d/l]

Thanks for all the suggestions. Haven't had time to work through them all yet but I was prompted to try SOAP::Simple. Couldn't find that on the Activestate ppm repository but gave SOAP::MySOAP a try. You have to pass in the raw xml in the request but it is passing the result back to me as expected. I'll take a closer look at the sites provided but for now I need to press on..deadlines ;) Thanks for the help	[reply]
