Hi folks,
I am having difficulties when attempting to send a message to a .NET web-service (written with vb).
This is an example of what is generated by JAX-RPC when it sends a message to the VB web-service. You'll notice that the namespace ns0 is defined and then the sendExternalEndpointForm element is prefixed with ns0 to qualify it for this namespace.
Although syntactically correct, the vb.net service ignores the contents of String_1 in this circumstance (writing an empty string to disk), even though the IIS server issues a 200 OK response, with a SOAP response that indicates success.
POST /trilogitest/Service1.asmx HTTP/1.1
Content-Type: text/xml; charset="utf-8"
Content-Length: 530
SOAPAction: "
http://www.trilogi.co.uk/clientxmlrpc/sendExternalEndpointForm"
Host: localhost
<?xml version="1.0" encoding="UTF-8"?><env:Envelope xmlns:env="
http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="
http://www.w3.org/2001/XMLSchema" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns:enc="
http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns0="
http://www.trilogi.co.uk/clientxmlrpc" env:encodingStyle="
http://schemas.xmlsoap.org/soap/encoding/"><env:Body><ns0:sendExternalEndpointForm><String_1 xsi:type="xsd:string">Some String Message</String_1></ns0:sendExternalEndpointForm></env:Body></env:Envelope>
However removing the ns0 definition and explicitly qualifying the namespace for sendExternalEndpointForm as show below resolves the issue, vb.net processes this next request perfectly, writing the string to a file on disk as expected:
POST /trilogitest/Service1.asmx HTTP/1.1
Content-Type: text/xml; charset="utf-8"
Content-Length: 518
SOAPAction: "
http://www.trilogi.co.uk/clientxmlrpc/sendExternalEndpointForm"
Host: localhost
<?xml version="1.0" encoding="UTF-8"?><env:Envelope xmlns:env="
http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="
http://www.w3.org/2001/XMLSchema" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns:enc="
http://schemas.xmlsoap.org/soap/encoding/" env:encodingStyle="
http://schemas.xmlsoap.org/soap/encoding/"><env:Body><sendExternalEndpointForm xmlns="
http://www.trilogi.co.uk/clientxmlrpc"><String_1 xsi:type="xsd:string">Some String Message</String_1></sendExternalEndpointForm></env:Body></env:Envelope>
I can appreciate that this may be considered a .NET interoperability issue but if anyone has any suggestions I would very much like to hear them.
Thanks in advance,
