Problem in saving...

Question

int packetsize=65536;
byte buffer=new byte[packetsize];
i use the above code to create a buffer where data from socket to be saved and then through a stream to store them into a file.
the problem is that if i send a packet bigger than 65536 packet...the file is completed but not correctly although the totalbytes are the same size with the totalsize of the file in disk...
is there a problem storing more than 65kb each time a packet comes?
p.write(buffer,0,packetsize);
p.flush();
this is how i save the packets...

Hello stefanosn,
For TCP connection we use ServerSocket at server side and Socket at client side.
Following example might help you
Server.java
import java.io.*;
import java.net.*;
public class  Server
     public static void main(String[] args) throws IOException
          int PORT = 8134;
          InputStream inStream;
          DataInputStream inDataStream;
          OutputStream outStream;
          DataOutputStream outDataStream;
          String message="";
          String received="";
          System.out.println("Chat Server Started");
          ServerSocket sock = new ServerSocket(PORT);
          Socket conn = sock.accept();     
          do{
          inStream = conn.getInputStream ();
          inDataStream = new DataInputStream ( inStream );
          message = inDataStream.readUTF();          
          System.out.println("Client sent: "+message);
          DataInputStream dis = new DataInputStream(System.in);
          message = dis.readLine();
          outStream = conn.getOutputStream();
          outDataStream = new DataOutputStream (outStream);     
          System.out.println("Enter your message here: ");
          outDataStream.writeUTF(message);     
          }while(!message.equals("bye"));
          conn.close();
Client.java
import java.net.*;
import java.io.*;
public class Client
     public static void main(String args[]) throws IOException
          int PORT = 8134;
          InputStream inStream;
          DataInputStream inDataStream;
          OutputStream outStream;
          DataOutputStream outDataStream;
          String message = "";
          InetAddress host = InetAddress.getLocalHost();
          String diffHost = args[0];
          Socket sock = new Socket(diffHost,PORT);
          System.out.println("Chat Client Started");
          do{
               System.out.println("Enter your message here: ");
               DataInputStream dis = new DataInputStream(System.in);
               message = dis.readLine();
               outStream = sock.getOutputStream();
               outDataStream = new DataOutputStream (outStream);          
               outDataStream.writeUTF(message);     
               inStream = sock.getInputStream ();
               inDataStream = new DataInputStream ( inStream );
               message = inDataStream.readUTF();
               System.out.println("Server Sent: "+message);
          }while(!message.equals("bye"));
}Compile, run .
i think you can get better idea.
