Missing bytes

Question

hi! im trying to read a byte array sent by a local server to a local client but when i print the array read from the stream the array is missing two bytes. here is where the problem occurs. please help me.
Client side:
public void GetFrame(Socket connection, String funcframe){
     StringBuffer instr = new StringBuffer();                         
     int frame = 0, index = 0;
     boolean notempty = true;
     try {                                                       
          InputStream in = connection.getInputStream();
          OutputStream osw = connection.getOutputStream();                                        
          osw.write(SOSFRAME);
          osw.flush();
          int c;               
          frame = in.read();
          if (frame == SOSRESPFRAME){                    
               byte[] bytearray = new byte[funcframe.length()+1];                              
               bytearray[0] = (byte)GETFRAME;
               System.out.println("bytearray length" + funcframe.length()+1);
               for (index = 0; index < funcframe.length(); index++){
                    if (funcframe.charAt(index) != ',' && funcframe.charAt(index)!= (char) 13){
                         System.out.println(" char at funcframe "+ funcframe.charAt(index));                    
                         bytearray[index + 1] = ((byte)(Character.digit((funcframe.charAt(index)), 16)));
                         System.out.println(" inside loop = "+ bytearray[index + 1]);
               osw.write(bytearray);
               osw.flush();
               in.read(bytearray); // this is where the problem occurs
               for(index = 0; index < bytearray.length; index++) {
                    System.out.println("bytearray"+ (char)bytearray[index] +" "+bytearray.length);
               if(bytearray[0] == (byte)GETRESPFRAME){
                    instr.setLength(0);
                    do{                         
                         if (bytearray[1] != 0){
                              System.out.println("error in set frame");
                              System.exit(-1);
                         else {          
                              System.out.println("value for " + (int)bytearray[2]);                         
                              for(index = 0; index < (int)bytearray[2]+1; index++) {
                                   System.out.println((char)bytearray[index + 3]);
                                   if (bytearray[index + 3] != 0)
                                        instr.append((char)bytearray[index + 3]);
                              if (bytearray[(int)bytearray[2] + 3] == 0) {
                                   notempty = false;
                    }while(notempty);
               /*     instr.setLength(0);
                    for(index = 0; index < Array.getLength(bytearray)-1; index++) {
                         if (bytearray[index + 1] != 0)
                              instr.append((char)bytearray[index + 1]);
          else {
               System.out.println("start of session response not recieved");                    
               connection.close();
          save(instr);
     catch (IOException e)
          System.err.println ("IOException: " + e);
Server side:
if (bytearray[0] == (byte)GETFRAME){
    packet = "";
    System.out.println("in get frame");
       File file = new File ("C:\\Program Files\\Xinox Software\\JCreatorV3LE\\MyProjects\\frame.txt");                              
     bytearray[0] = (byte)GETRESPFRAME;
     byte[] filearray = new byte [getBytesFromFile(file).length];
     System.out.println("getBytesFromFile(file).length"+getBytesFromFile(file).length);
     filearray = getBytesFromFile(file);
     copyArray(filearray, bytearray, 1);
    out.write(bytearray); // this is where the bytes that i meant is being written
    for(index = 0; index < filearray.length + 1; index++) {
          System.out.println("## "+(char)bytearray[index]);
    out.flush();                                      
}          I really need help.. thanks.

Answer 1

in.read(bytearray); // this is where the problem occursIt sure is. This function returns an important value which you are ignoring.
