Iphone NSStreamDelegate issues connecting to java socket server - iphone

Question

I am trying to open a socket connection from my iphone simulator and send a simple NSString to a localhost server I set up with java in port 80.
The problem that I have is that when I write data on the NSOutputStream its not being received by the server until I close the simulator. And then the server receives the data and this exception is thrown java.net.SocketException: Broken pipe
I know is something related with closing the NSOutputStream and flushing, but how can I achieve this in Objective c?
I call the ProtocolCommunication in my initial ViewController like this:
protocol = [[ProtocolCommunication alloc] init];
[protocol initNetworkCommunication];
[protocol sendData];
ProtocolCommunication class (IOS)
#implementation ProtocolCommunication
#synthesize inputStream, outputStream
- (void) initNetworkCommunication {
CFReadStreamRef readStream;
CFWriteStreamRef writeStream;
CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)#"localhost", 80, &readStream, &writeStream);
inputStream = (NSInputStream *)readStream;
outputStream = (NSOutputStream *)writeStream;
[inputStream setDelegate:self];
[outputStream setDelegate:self];
//do the Looping
[inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[inputStream open];
[outputStream open];
NSLog(#"INIT COMPLETE");
}
- (void) sendData {
NSString *response = #"HELLO from my iphone";
NSData *data = [[NSData alloc] initWithData:[response dataUsingEncoding:NSASCIIStringEncoding]];
[outputStream write:[data bytes] maxLength:[data length]];
}
Java Server
String msgReceived;
try {
ServerSocket serverSocket = new ServerSocket(80);
System.out.println("RUNNING SERVER");
while (running) {
Socket connectionSocket = serverSocket.accept();
BufferedReader inFromClient = new BufferedReader(
new InputStreamReader(connectionSocket.getInputStream()));
DataOutputStream outToClient = new DataOutputStream(connectionSocket.getOutputStream());
msgReceived = inFromClient.readLine();
System.out.println("Received: " + msgReceived);
outToClient.writeBytes("Aloha from server");
outToClient.flush();
outToClient.close();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Any Ideas??

I solved it by just adding \n to the NSString like this:
NSString *response = #"HELLO from my iphone \n"; // This flushes the NSOutputStream so becarefull everyone
