iOS Problem with NSStream Sending the XML string to WS...!!!!!!

[RashiMahajan]

Hi,
I am trying to post my XML string to the server by using stream, Posting my code as follow:

- (void)_startSend:(NSString *)message
{
	NSString *data = message;
	[self setOutData:message];
	NSData *streamData = [data dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"abc.com"]];
	
	CFReadStreamRef readStream;
	CFWriteStreamRef writeStream;
	CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"abc.com", 80, &readStream, &writeStream);
	
	self.outStream = [[NSOutputStream alloc]initToMemory];
	self.inStream = (NSInputStream *)readStream;
	self.outStream = (NSOutputStream *)writeStream;
	
	[self.inStream retain];
	[self.outStream retain];

	[self.inStream setDelegate:self];
	[self.outStream setDelegate:self];
	[self.inStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
	[self.outStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
	[self.inStream open];
	[self.outStream open];

	
    self.inStream =[NSInputStream inputStreamWithData:streamData];

	NSUInteger fileLength = [streamData length];
	
	[request setHTTPMethod:@"POST"];
	//[request setHTTPBodyStream:self.inStream];
	[request setTimeoutInterval:200];
	
	[request setValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
	[request setValue:[NSString stringWithFormat:@"%i", fileLength] forHTTPHeaderField:@"Content-Length"];
	[request setValue: @"xmyx" forHTTPHeaderField:@"SOAPAction"];

		
	
	NSURLConnection *theConnection = [[[NSURLConnection alloc] initWithRequest:request delegate:self]retain];
	if( theConnection )
	{
		webData = [[NSMutableData data] retain];
		
	}
	else
	{
	}
	
}

In Delegates :

- (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)streamEvent
{
	
	NSLog(@"I am in stream delegate & stream is %@ wd event is %i",aStream, streamEvent);
	
	switch(streamEvent) {
        case NSStreamEventHasBytesAvailable:
			NSLog(@"I am here  NSStreamEventHasBytesAvailable");
			
		   uint8_t buffer[1024];  
                int len;  
		if([self.inStream hasBytesAvailable])
                {  
			NSLog(@"The stream is reading");
                    len = [self.inStream read:buffer maxLength:sizeof(buffer)];  
                    if (len > 0)  
                    {  
                        NSString *output = [[NSString alloc] initWithBytes:buffer length:len encoding:NSASCIIStringEncoding];  
						NSData *theData = [[NSData alloc] initWithBytes:buffer length:len];

						if (nil != output)  
                        {  
                          NSArray * bufferArray = [[NSArray alloc] init];  
                            bufferArray = [output componentsSeparatedByString:@"\n"];  
                            NSLog(@" OutPUt is %@", output);  
                            [output release];  
                        }  
                    }  
                }  
			
			
			
			
			break;
        case NSStreamEventEndEncountered:
			NSLog(@"I am here  NSStreamEventEndEncountered");
			break;
        case NSStreamEventHasSpaceAvailable:
			NSLog(@"I am here  NSStreamEventHasSpaceAvailable");
			
			NSData *streamData = [outData dataUsingEncoding:NSUTF8StringEncoding];
			uint8_t* buf=(uint8_t*)[outData UTF8String];
			[self.outStream write:buf maxLength:strlen((char*)buf)];  
			if(len>0)
			{
				NSLog(@"command send");
				[self.outStream close];
			}
	}

i get the call for NSStreamEventHasSpaceAvailable in delegate function while hitting the Web services but i receive 0 bytes in response. but if i uncomment the line //[request setHTTPBodyStream:self.inStream]; i get error from the server that root elemnt cant be null blahhh blahhh .......... i have never worked on the streaming stuff before so this is quite annoying ... Could any one let me know/ share code snippets for posting my XML string to the server by using streaming.... I will be very thankful to you..........


Waiting for loads of replies buddies.......
