Question

EDIT: After some research, I found the answer to the problem (at least it works for my particular situation). Instead of the register call noted down below, I am now using the following call:

$soap->register(
                 MyFunction ,
                array( inputData  =>  xsd:string ),
                array( outputData  =>  xsd:string ),
                $namespace,
                $namespace . "#MyFunction",
                "rpc",
                "literal",
                "My description.");

I guess the "rpc" and "literal" arguments are the key to the success. Hopefully this will help some other users facing the same problem.

I have a problem with a new project, where a silverlight application is to request data from a NuSoap-service. As this integration is rather new to me and unfortunately not many resources concerning this topic can be found on the internet (none addressing my problem at least), I hope that someone can point me into the correct direction.

The NuSoap-part is implemented like this:

<?php
   require_once( ../soap/nusoap/nusoap.php );

   $namespace = "http://127.0.0.1/adminSoap";
   $soap = new Soap_Server();
   $soap->configureWSDL( MyService , $namespace);
   $soap->wsdl->schemaTargetNameSpace = $namespace;
   $soap->soap_defencoding =  utf-8 ;

   $soap->register(
                 MyFunction ,
                array( inputData  =>  xsd:string ),
                array( outputData  =>  xsd:string ),
                $namespace

   );

   $soap->service(isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA :   );

   function MyFunction($inputData)
   {
       return "ok";
   }

?>

I then add a web reference to this service and get the dialog where I can select the service, its ServicePortType as well as "MyFunction".

If I generate the reference however, I would assume to find automatically generated asynchronous messages for MyFunction (i.e. MyFunctionAsync and the MyFunctionCompleted.event). These do not exist.

What could I be doing wrong. Here s the code that sets up the client:

ServiceReference4.MyServicePortTypeClient client = new SilverlightTest1.ServiceReference4.MyServicePortTypeClient();

Any ideas why the asynchronous method is not available?

Here s the generated WSDL, if that s of any help, btw (hyphens due to copy/paste from IE):

I working on a similar problem. I was using Zend_Soap (which just wraps the PHP SOAP extension), and using a Silverlight Service Reference to connect to it. It seems that the Silverlight Service implementation cannot make us of soap-encoded operations. If you look at the WSDL under each has an and . In those tags are the the attributes that damn us both to frustration. The use="encoded" and encodingStyle="blah, blah" attributes.

I now know that Zend_Soap will only make bindings that use soap-encoding. I m not sure yet about nuSoap.

If you can change the PHP backend, you might look into Midnight Coders WebORB for PHP and Silverlight. It includes a solution for both the server and the client that work together. It is available for free for certain circumstances. Due to licensing issues, I don t I ll be able to us it.
