Making SOAP call using Perl's SOAP::Lite and a WSDL file - perl

Question

I want to make a SOAP call to a local web service. The web service is defined via a WSDL file (see below). I want to use Perl and SOAP::Lite. I tried this:
use strict ;
use warnings ;
use SOAP::Lite ;
my $endpoint = qq{http://example.com:2222/orawsv/PS_API/ACCOUNT_WS} ;
my $tns = 'http://xmlns.oracle.com/orawsv/PS_API/ACCOUNT_WS' ;
my $method_urn = $tns ;
my $soapaction = $tns ;
my $method = 'GET_BY_ACCOUNT_NUMBER' ;
my $sObj = SOAP::Lite->new(uri => $soapaction, proxy => $endpoint) ;
my $response = $sObj->call(SOAP::Data->name($method)->attr({ 'xmlns' => $method_urn})
=> SOAP::Data->name('ACCOUNT_NUMBER-VARCHAR2-IN' => '274724')) ;
print $response->faultstring() . "\n";
However, this results in an XML parsing failed error message. What would be the correct SOAP::Lite code to make this method call?
The HTTP request generated by the above is
Accept: text/xml
Accept: multipart/*
Accept: application/soap
Content-Length: 553
Content-Type: text/xml; charset=utf-8
SOAPAction: "http://xmlns.oracle.com/orawsv/PS_API/ACCOUNT_WS#GET_BY_ACCOUNT_NUMBER"
<?xml version="1.0" encoding="UTF-8"?><soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<GET_BY_ACCOUNT_NUMBER xmlns="http://xmlns.oracle.com/orawsv/PS_API/ACCOUNT_WS">
<ACCOUNT_NUMBER-VARCHAR2-IN xsi:type="xsd:int">274724</ACCOUNT_NUMBER-VARCHAR2-IN>
</GET_BY_ACCOUNT_NUMBER>
</soap:Body>
</soap:Envelope>
Here is the WSDL file defining the web service:

Answer 1

Since you have the WSDL, you shouldn't have to construct SOAP::Data objects at all. Simply load the WSDL into your client object and call the method directly:
my $client = SOAP::WSDL->new(wsdl => $url_of_wsdl);
my $result = $client->$method(#arguments);
Yes, it's that easy!

Answer 2

Looks like this is about a year old, so this might not be relevant any longer. Anyway, based on the soap::lite documentation on CPAN it looks like you want to do this:
my $response = $sObj->call(SOAP::Data->name($method)->attr({ 'xmlns' => $method_urn}),
SOAP::Data->name('parameters')->value(SOAP::Data->value([
SOAP::Data->name('ACCOUNT_NUMBER-VARCHAR2-IN' => '274724'),
]))
);
die $response->fault->{ faultstring } if ($response->fault);
print $response->result, "\n";
