in reply to SOAP::Lite & WSDL Problem

You can debug a bit:

... use SOAP::Lite +trace => 'all'; ... SOAP::Transport::HTTP::Client::send_receive: HTTP/1.1 500 Internal Ser +ver Error. ... <soap:Fault> <faultcode>soap:VersionMismatch</faultcode> <faultstring>System.Web.Services.Protocols.SoapException: Possib +le SOAP version mismatch: Envelope namespace http://schemas.xmlsoap.o +rg/wsdl/soap/ was unexpected. Expecting http://schemas.xmlsoap.org/so +ap/envelope/. at System.Web.Services.Protocols.SoapServerProtocol.CheckHelperVers +ion() at System.Web.Services.Protocols.SoapServerProtocol.ReadParameters( +) at System.Web.Services.Protocols.WebServiceHandler.Invoke() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessReque +st()</faultstring> <detail /> </soap:Fault>

You might want to look in the "INTEROPERABILITY" section in the SOAP::Lite docs. Note that there's also a SOAP::WSDL module that I've noticed being worked on recently but haven't tried yet.
