Trying to capture line feed or carriage return

Question

We have a socket application. We would like to know what is the line terminating character? Below is a snippet of codes. Any comments if this is right?
BufferedReader readerBuffer = null;
readerBuffer = new BufferedReader(new InputStreamReader(sockConn1.getInputStream()));
int readChar=0;        
while ((readChar=readerBuffer.read()) != -1)
     System.out.println("Read char "+(char) nextChar); 
}

Answer 1

Below is the full codes without the db connection and processing as we see that will be too long here.
public class deviceServer {
  class deviceConnectionHandler implements Runnable {
    private Socket sockConn1;
    deviceConnectionHandler(Socket receivedSocketConn1) {
      this.sockConn1=receivedSocketConn1;
     Connection dbConnection = null;
     Statement dbStmt = null;
     public void run() {
     String completeMessage="";
     BufferedReader readerBuffer = null;    
    BufferedWriter writeBuffer = null;
     try {
         readerBuffer = new BufferedReader(new InputStreamReader(sockConn1.getInputStream()));
         writeBuffer = new BufferedWriter(new OutputStreamWriter(sockConn1.getOutputStream()));
         int readChar=0;        
         sockConn1.setSoTimeout(120000);
       //dbConnection = connectionPool.getConnection();
         //dbConnection.setAutoCommit(false);
             while ((readChar=readerBuffer.read()) != -1)
                       System.out.println("Read Char : "+(char) readChar);
                       completeMessage += (char) readChar; 
                     if (readChar == '*') {
                     try {
                      writeBuffer.write("@@\r\n\r\n");
                     writeBuffer.flush();                    
                      //db processing
                       dbConnection.commit();
                    catch (SQLException ex){
                         ex.printStackTrace();
                            try{   
                                dbConnection.rollback(); 
                                catch (Exception rollback){   
                                     rollback.printStackTrace();
                     catch (Exception e){
                           e.printStackTrace(System.out);
                               try{   
                                dbConnection.rollback(); 
                                catch (Exception rollback){   
                                     rollback.printStackTrace(System.out);
                     finally{
                            try{
                                 if ( dbStmt != null ){
                                   dbStmt.close();
                            catch(SQLException ex){
                            ex.printStackTrace(System.out);
                   completeMessage="";          
           catch (SocketTimeoutException ex){
                ex.printStackTrace();
           catch (IOException ex){
                ex.printStackTrace();
           catch (Exception ex){
                ex.printStackTrace();
           finally{
             try{
                  if ( dbConnection != null ){
                    dbConnection.close();
             catch(SQLException ex){
                 ex.printStackTrace();
             try{
                 if ( writeBuffer != null ){
                         writeBuffer.close();
             catch(IOException ex){
                ex.printStackTrace(System.out);
   public static void main(String[] args) {
      new deviceServer();
   deviceServer() {
      /*try {
      // setup the connection pool
      catch (SQLException e) {
         e.printStackTrace(System.out);
      try{
            final ServerSocket serverSocketConn = new ServerSocket(7000);                    
            while (true){
               try{
                   Socket socketConn1 = serverSocketConn.accept();
                 new Thread(new deviceConnectionHandler(socketConn1)).start();                          
               catch(Exception e){
                  e.printStackTrace();
      catch (Exception e){
         e.printStackTrace();
