I have been trying to write a objective-c application for ipad to send/receive soap web service. I have written a code but it gives an error. the webservice is working online.
here is my code,
-(IBAction)invokeService
{
[txt1 resignFirstResponder];
NSString *soapFormat = [NSString stringWithFormat:
@"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<GetUserList xmlns=\"http://tempuri.org/\" />\n"
"</soap:Body>\n"
"</soap:Envelope>\n"];
NSLog(@"The request format is %@",soapFormat);
NSURL *locationOfWebService = [NSURL URLWithString:@"http://servicing2.rotanet.com/service1.asmx"];
NSLog(@"web url = %@",locationOfWebService);
NSMutableURLRequest *theRequest = [[NSMutableURLRequest alloc]initWithURL:locationOfWebService];
NSString *msgLength = [NSString stringWithFormat:@"%d",[soapFormat length]];
[theRequest addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:@"GetUserList" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
//the below encoding is used to send data over the net
[theRequest setHTTPBody:[soapFormat dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *connect = [[NSURLConnection alloc]initWithRequest:theRequest delegate:self];
if (connect) {
webData = [[NSMutableData alloc]init];
startActivityIndicator;
}
else {
NSLog(@"No Connection established");
}
}
I get this error message
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault> <faultcode>soap:Client</faultcode><faultstring>System.Web.Services.Protocols.SoapException: Server did not recognize the value of HTTP Header SOAPAction: GetUserList.

what am I doing wrong?

Creating simple SOAP requests are easy, however when you have complex graph of objects, dealing with Dictionaries and raw XML can be time consuming, WSClient++ generates Objective C source code for SOAP proxy with each complex type. You just make a single method call to retrieve results.
