POST XML request to 'REST' service url from iPhone - xcode4

Question

I m pretty much new to objective-C and strucked at a point.I have to POST XML request to rest service url and get the response from it .I m using NSMutableRequest.But couldn't see any response.Couldn't understand where I m going wrong ...
Request XML is like this:
<GetUserRequest xmlns="http://schemas.datacontract.org/2004/07/DModel" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<ID>456789</ID>
<UserEmail>John#yahoo.com</UserEmail>
</GetUserRequest>
My url is like this : http://192.158.0.104:8732/IServices/GetXml
MY code goes like this :
NSString *urlString1=[NSString stringWithFormat:#"http://192.158.0.104:8732/IServices/GetXml"];
NSMutableURLRequest *request=[[[NSMutableURLRequest alloc] init]autorelease];
[request setURL:[NSURL URLWithString:urlString1]];
[request setHTTPMethod:#"POST"];
NSString *contentType=[NSString stringWithFormat:#"application/xml"];
[request addValue:contentType forHTTPHeaderField:#"Content-type"];
NSMutableData *postBody=[NSMutableData data];
[postBody appendData:[[NSString stringWithFormat:#"<GetUserRequest xmlns=\"http://schemas.datacontract.org/2004/07/DModel\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">"]dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"<ID>456789</ID>"]dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"<UserEmail>John#yahoo.com</UserEmail>"]dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:#"/GetUserRequest>"]dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postBody];
NSHTTPURLResponse *urlResponse=nil;
NSError *error=[[NSError alloc]init];
NSData *responseData=[NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];
NSString *rss=[[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding ];
NSlog(#"Response Code:%d",[urlResponse statusCode]);
if([urlResponse statusCode ]>=200 && [urlResponse statusCode]<300)
{
NSLog(#"Response:%#",rss);
}
But I couldnot see anything in active console...
Any help would be appreciated ...

That code looks poor to me and doesn't contain enough error checking ([NSURLConnection sendSynchronousRequest] can return nil when an error occurs). Modify the end to:
NSError *error = nil;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request
returningResponse:&urlResponse
error:&error];
if (responseData != nil)
{
NSString *rss = [[NSString alloc] initWithData:responseData
encoding:NSUTF8StringEncoding ];
NSlog(#"Response Code:%d",[urlResponse statusCode]);
if([urlResponse statusCode ]>=200 && [urlResponse statusCode]<300)
{
NSLog(#"Response:%#",rss);
}
}
else
{
NSLog(#"Failed to send request: %#", [error localizedDescription]);
}
