Why the socket is closing

Question

Hi ,
I would like to send the MimeMessage object via socket connection. To do do that i have written the following code fragment
Socket s = new Socket("localhost",3200);
OutputStream os = s.getOutputStream();
MimeMessage mimemessage
//some code to create MimeMessage
mimemessage.writeTo(os);
os.close() // this is important step
In this code fragment if i didnt close the output stream the message is not being delivered to the server side. But when i close the output stream it is closing the socket connection with the stream connection.
What i neeed is i will be sending mimemessage objects via socke asynchronously. For that purpose i would like to keep the outputstream of the socket keep opent always. But how can i send the mimemessage object via socket without closing the stream.
I tried os.flush() also. but no result.
Please help me.
thanks in advance,

I am not using any server n server is simple java server socket.
here is the code for server
public class MyServer extends Thread
public static void main(String[] a)
ServerSocket sss= newServerSocket(3200);
while(true)
Socket s = ss.accept();
new MyServer(s).start();
public MyServer(Socket socket)
this.socket = socket;
is = socket.getInputStream();
public void run()
while(true)
Properties prop = System.getProperties();
Session session = Session.getInstance(prop, null);
MimeMessage mimemessage = new MimeMessage(session,objectStream);
// do some operations on this message
