DidReceiveData not getting called for consuming a SOAP webservice

Question

I am trying to access a webservice in iphone. didReceiveResponse connectionDidFinishLoading is getting called however didReceiveData is not getting called. I checked NSHTTPURLResponse allHeaderFields where Content-length is 0 and statusCode is 400. I am not getting why I am getting this HTTP status code. Can someone please help me in finding this error. Here is my code:
- (IBAction)buttonClickedid)sender {
NSString *soapMsg =
[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\" xlmns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<GetAllCarsJson xmlns=\"http://cscserver2.carrollu.edu/tshah2/\">\n"
"</GetAllCarsJson>\n"
"</soap:Body>\n"
"</soap:Envelope>"];
//---print it to the Debugger Console for verification---
//NSLog(@"%@",soapMsg);
NSURL *url = [NSURL URLWithString:@"http://cscserver2.carrollu.edu/tshah2/CarService.asmx"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
//---set the headers---
NSString *msgLength = [NSString stringWithFormat:@"%d",[soapMsg length]];
[req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[req addValue:@"http://cscserver2.carrollu.edu/tshah2/GetAllCarsJson" forHTTPHeaderField:@"SOAPAction"];
[req addValue:msgLength forHTTPHeaderField:@"Content-Length"];
//---set the HTTP method and body---
[req setHTTPMethod:@"POST"];
[req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];
//[activityIndicator startAnimating];
conn = [[NSURLConnection alloc] initWithRequest:req delegate:self];
[conn start];
NSLog(@"Connection = %@", conn);
if (conn)
    //webData = [[NSMutableData data] ];
    webData = [[NSMutableData alloc] initWithCapacity:2048];
    //[[NSMutableData data] retainArguments];
- (void) connection NSURLConnection *) connection didReceiveResponse NSURLResponse *)response
    NSLog(@"soapMsg1: %d", [webData length]);
    //webData = [[NSMutableData alloc] initWith:
    [webData setLength:0];
- (void) connection NSURLConnection *) connection didReceiveData NSData *)data
    NSLog(@"DONE1111");
    [webData appendData:data];
    //NSLog(webData);
- (void) connection NSURLConnection *) connection didFailWithError NSError *)error
    NSLog(@"ConnectionFailed");
    //[webData release];
    //[connection release];
- (void) connectionDidFinishLoading NSURLConnection *) connection
    NSLog(@"DONE. Received Bytes: %d", [webData length]);
    NSString *theXML = [[NSString alloc] initWithBytes:[webData mutableBytes] length:             [webData length] encoding:NSUTF8StringEncoding];
    //shows the XML
    NSLog(theXML);
    //[theXML release];
    //[activityIndicator stopAnimating];
    //[connection release];
    connection = nil;
    webData =nil;

Hi,
If you can see the field in UI and still get_ method is not being triggered then try to regenerate these methods. If it still doesn't work then please look for SAP notes or raise an OSS.
There should be some note for the issue you faced.
please refer:
