Socket Programming-Not getting response from server.

Question

Hi,
I am trying to communicate with server using java socket programming, I am getting the response for first two times third time when I am trying to write some thing I am not getting any response from the server,
I am writing to migrate the vb code to Java the vb is using a c++ dll to communicate with the server and we tried accessing the dll from java using JNI then it is working fine, this dll is dependent on windows so we want to avoid the dependency with windows that is why we are going for socket programming, Please help on this.

Hi,
I am writing the data in forms of string
like
Socket sockt = new Socket(ipAddress, portNo);     
out= new DataOutputStream(sockt.getOutputStream());
in = new DataInputStream(sockt.getInputStream());
out.writeBytes("Serv");
out.writeBytes("Serv,32");
out.writeBytes("home,serv32,run.prg,sucess");
these are the strings to communicate with server.
I am trying to read the same
StringBuffer buf = new StringBuffer();
          byte b = '\0';
                    try {
               while ((b = in.readByte()) != '\0')
                    char ch = (char) b;
                    buf.append(ch);
          } catch (Exception e) {
               System.out.println(e.getStackTrace());
we are getting the response for the first two strings, but for the third string it is getting stucked for some time and returing some junk values like '???' we are sending the same string using JNI and it is working.
