Few things are not clear from your post, like, are you using sockets and if you are, how are u reading writing to them (ur sample code would help)...
Anyways if you are, are you doing accept on your socket in a while(true) loop or just once... If you do it only once you will get the first ping message but none afterwards if the other side closes and opens new sockets for every send... What I am suggesting is something like the following:
ss = new ServerSocket(port);
while(true)
     s = ss.accept();
     is = s.getInputStream();
     os = s.getOutputStream();
     reader = new BufferedReader(new InputStreamReader(is));
     writer = new BufferedWriter(new OutputStreamWriter(os));
     String in = reader.readLine();
        // do something with this string
        s.close();
        // put some check here to break out of this infinite loop
}// end of While
