File transfer from Client to server

[xemeGa]

hi,,

I've been trying to make an application where the user select several fiels using JFileChooser and then the program read all the files and then save the content of all in 1 file and then send it to the server using client/server sockets, I've tried many ways and non seems to working .So whats the proper way to do it ?

public class Main {

static File[] f;


public static void main(String[] args) throws Exception {
JFileChooser jf = new JFileChooser("C:");
jf.setMultiSelectionEnabled(true);
jf.showOpenDialog(null);
int count=0;
f = jf.getSelectedFiles();

File allinone = new File("All.dat");
JFileChooser jf2 = new JFileChooser(allinone);
int returnVal = jf2.showSaveDialog(null); 


DataOutputStream dos = new DataOutputStream(new FileOutputStream(allinone));
FileInputStream fis=null;


for (int i = 0; i < f.length; i++) {


fis = new FileInputStream(f[i]);

int fileSize = (int) f[i].length();

byte[] b = new byte[fileSize];

fis.read(b);
String text=new String(b);
String filename = f[i].getName();

System.out.println("FIle name " + filename + " size = " + fileSize);

dos.writeUTF(filename);
dos.writeUTF(text);
dos.flush();


fis.close();

count= count+2;

}
dos.writeUTF("TheEnd");
dos.close();

// Thats the part which on client side,then i want to send the file allinone.dat to the server to do the following


DataInputStream dis = new DataInputStream(new FileInputStream(allinone));   //the part where i want to replace allinone with the incoming file from the client socket


while(count!=0){ 

String fn=dis.readUTF();
System.out.println(fn); // test
String text=dis.readUTF();
System.out.println(text); // test
count=count-2;
byte[] textB=text.getBytes();
File f=new File("new"+fn);
FileOutputStream ff=new FileOutputStream(f);
DataOutputStream dd=new DataOutputStream(ff);

dd.write(textB);

}
dis.close();
}
}
