Hi Jeff,
thanks again for answering so quickly

When I try to access your WSDL, I get:

Sorry about that, should be fixed now. Seems the development box ran
out of diskspace. :-/
Generally, though, I don't believe the response from a web service
is a dictionary - I believe it's usually a string and I'm wondering
why you are sending an empty dictionary - it would seem like nil
would be a better choice if you want to send without any data.
Perhaps I misunderstood, but I thought an empty dictionary means no
arguments? Passing nil is not an option as it gives this error:
*** -[NSCFDictionary initWithObjects:forKeys:count:]: attempt to
insert nil value at objects[0] (key: parameters)
Passing an empty string is still passing an argument, and I still get
testStr==nil when I do:
NSString *testStr = (NSString*) [myService testString:@""];
I also tried passing an empty NSArray thinking that it would be a nice
way of representing parameters, but again I got testStr==nil
The reason I expect that the regular parameter will be a dictionary
is that I would like to pass objects back and forth. For instance, in http://78.157.102.46:2234/DummyWS/Service1.asmx
I've defined getValidAuth() that returns a valid Authentication
object, and I would like to do something like
NSDictionary *authDict = [WS getValidAuth];
NSNumber *successBool = [WS testAuth:authDict];
if(successBool.boolValue)
NSLog(@"Success");
else
NSLog(@"Fail");
One issue I've become more suspiscious
Also, you are leaking memory there since your code will never
release the dictionary you allocated in the first line of your method.
I've turned on garbage collection, so I didn't worry about that.
Let's see, what else...
You say there is some network activity, so why don't you try using
tcpdump to see what is being passed back and forth. It would be
something like this in a terminal window:
sudo tcpdump -s 0 -v -A -i en1 port 2234
Sure. This is a valid SOAP request for testString:
POST /DummyWS/Service1.asmx HTTP/1.1
User-Agent: Mac OS X; WebServicesCore.framework (1.0.0)
Host: 78.157.102.46:2234

Soapaction: http://webservice.mydomain.com/testString
Content-Length: 530
Connection: close
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:xsd="http://www.w3.org/2001/XMLSchema";

<SOAP-ENV:Body>
<testString xmlns="http://webservice.mydomain.com/";>
</testString>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
and it gives the correct result:
HTTP/1.1 200 OK

</soap:Body></soap:Envelope>
Passing an empty array as parameter I get:
POST /DummyWS/Service1.asmx HTTP/1.1
User-Agent: Mac OS X; WebServicesCore.framework (1.0.0)
Host: 78.157.102.46:2234

<parameters SOAP-ENC:arrayType="xsd:anyType[0]"
xsi:type="SOAP-ENC:Array">
</parameters>
</m:testString>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The only difference for an empty dictionary is that <parameters> has
xsi:type="SOAP-ENC:Dictionary"
Why is testString prepended by "m:" ?? Why is the namespace anonuri
rather than http://webservice.mydomain.com/? Why is Soapaction
SOAPAction rather than http://webservice.mydomain.com/testString ??
Calling testString with an empty string gives:
POST /DummyWS/Service1.asmx HTTP/1.1
User-Agent: Mac OS X; WebServicesCore.framework (1.0.0)
Host: 78.157.102.46:2234

<m:testString xmlns:m="http://anonuri/";>
<parameters xsi:type="xsd:string"></parameters>
</m:testString>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The response from the server is then:
