iphone file download not working

Question

Hi, In my app I 'm first connecting to a web service, which in return sends a url for a file. I use the url to download the file and then display it on the new view.

I get the correct URL but not able to download file from that location. I have another test app which will download file from the same location and it works like a charm.

following is my code for webservice-file download. This is a snippet of the code where i 'm parsing the web service xml and then pass the result to NSData for file download.

Any suggestions where am i going wrong ??

I 'm referring to the following tutorials.

if ([elementName isEqualToString:@"PRHPdfResultsResult"])
    {

        NSLog(soapResults);        
         UIAlertView *alert = [[UIAlertView alloc] 
         initWithTitle:@"Report downloaded from:" 
         message:soapResults 
         delegate:self  
         cancelButtonTitle:@"OK" 
         otherButtonTitles:nil];

        NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:soapResults]];
        //Store the Data locally as PDF File

        NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:@"Documents"]];

        NSString *filePath = [resourceDocPath stringByAppendingPathComponent:@"myPDF.pdf"];

        [pdfData writeToFile:filePath atomically:YES];
        [alert show];
        [alert release];
        [soapResults setString:@""];
        elementFound = FALSE; 
    }
