soap-server.pl
#!/usr/bin/perl

return "some string";
}
marketplace.wsdl
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="Marketplace"
targetNamespace="urn:Marketplace"

<output message="tns:LoginResponse"/>
</operation>
</portType>
<binding name="LoginBinding" type="tns:LoginPort">
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="login">

</operation>
</binding>
<service name="WSDLService">
<port name="LoginPort" binding="tns:LoginBinding">
