Objective-C SOAP Client --Request Problem?

Question

I have generated code with WSDL2OBJC. I have big problem with request in my Objective C client:

CatalogoPortBinding *binding = [[CatalogoSvc CatalogoPortBinding] initWithAddress:@"http://localhost:8080/WSServer/Catalogo_V1"];
    binding.logXMLInOut = YES;  // to get logging to the console.

    CatalogoSvc_hello *request = [[CatalogoSvc_hello alloc] init];

    NSString *t = @"David";
    request.name = t;

    NSLog(@"request: %@",request.name);

    CatalogoPortBindingResponse *response = [binding helloUsingParameters:request];


    //NSLog(@"%@",resp.bodyParts);
    for (id mine in response.bodyParts)
    {

        NSLog(@"name: %@",[mine return_]);
        if ([mine isKindOfClass:[CatalogoSvc_helloResponse class]])
        {   
            if (sec == YES) {

                //NSLog(@"name: %@",[mine return_]);
                NSString *texto = (NSString*)[mine return_];
                [lab setText:(NSString*)texto];
            }
        }

    }

my console show:

2011-08-31 12:29:05.086 Catalogo-V1[3596:207] request: David
2011-08-31 12:29:05.088 Catalogo-V1[3596:207] OutputHeaders:

    "Content-Type" = "text/xml; charset=utf-8";
    Host = localhost;
    Soapaction = "";
    "User-Agent" = wsdl2objc;
}

    "Transfer-Encoding" = Identity;
    "X-Powered-By" = "Servlet/3.0 JSP/2.2 (GlassFish Server Open Source Edition 3.1.1 Java/Apple Inc./1.6)";
}
2011-08-31 12:29:05.094 Catalogo-V1[3596:207] ResponseBody:

2011-08-31 12:29:05.095 Catalogo-V1[3596:207] name: Hello null !

I need to show this message: "Hello David !" and i receive: "Hello null!".

Answer 1

Based on comparing this request to what you have in your question posted about a manual solution, it looks like you've got namespace issues happening here. The SOAP request generated here applies the http://org/ namespace (via the identifier CatalogoSvc) to the "name" element:

<CatalogoSvc:hello>
  <CatalogoSvc:name>David</CatalogoSvc:name>
</CatalogoSvc:hello>

In the manual scenario where you have gotten this to work, the http://org/ namespace is applied to the surrounding "hello" element but not the "name" element:

<ns2:hello xmlns:ns2="http://org/>
    <name>david</name>
</ns2:hello>

Based on this observation, I would deduce that your service is not expecting a namespace to be applied to the name element, so it is not finding that parameter when it is sent with a namespace.

To fix this problem you will need to either:

1. Figure out how to tell the SOAP client stub generation to NOT apply a namespace to your parameter, or
2. Update your service to make it expect a namespaced "name" element.

Since the client side code is presumably generated from the service's WSDL, I suspect that the Objective-C code is doing it right and your service code has it wrong, but that's just a suspicion. Either way, you need to find a way to make client and server side "agree"

Answer 2

i had same problem until suggestion at below...

According to what you've shown from your console, the XML request you formulated is invalid. You have

<ns2:hello xmlns:ns2="http://org/" />
    <name>david</name>
</ns2:hello>

But you should have (note the removal of the invalid XML tag termination):

<ns2:hello xmlns:ns2="http://org/>
    <name>david</name>
</ns2:hello>

Also note that your working sample request includes a soap:Header element, and yours does not. That is unlikely to be the problem here though.
