i am trying to send all kind of files from java client to c++ server. all kind of text files are transferred successfully. but when it comes to pdf,image,.iso files, it produces errors like pdf load error, cannot open image, not in .iso format . below i am attaching the c++ server code and java client code.please help me to rectify it.
client1.java
import java.net.*;
import java.io.*;
class client1{
public static void main (String[] args){
DataInputStream input;
String str;
BufferedInputStream bis;
BufferedOutputStream bos;
int in;
byte[] byteArray;
try{
Socket client = new Socket(args[0],Integer.parseInt(args[1]));
System.out.println("enter file");
DataInputStream din1=new DataInputStream(System.in);
str=din1.readLine();
bis = new BufferedInputStream(new FileInputStream(str));
bos = new BufferedOutputStream(client.getOutputStream());
byteArray = new byte[1024];
while ((in = bis.read(byteArray)) != -1){
bos.write(byteArray,0,in);
Thread.sleep(4000);
System.out.println(byteArray);
bos.flush();
}
System.out.println("send successfully");
}
catch ( Exception e ) { }
}}
