Need Server to know name of Transfering File

[Gregg Bolinger]

Ok, I have written a little bitty Client and Server program that I can use to send files to a Server in my network. Just doing this to learn java sockets. My question is how can I tell the Server what the name of the file is that is being transfered so it know what filename to give the tranfering file.
Here is my code

///////////////////////////////////////////////////////
//Client.java
//Usage: java Client ipaddress port file
///////////////////////////////////////////////////////
//Imports
import java.net.*;
import java.io.*;
public class Client {


//Main Method
public static void main(String[] args) {


//Get IP from command line
String host = args[0];

//Get port from command line and parse from string to int
int port = Integer.parseInt(args[1]);

//Creating Streams
BufferedInputStream fileIn = null;
BufferedOutputStream out = null;

//Create file based on file from command line
File file = new File(args[2]);

//Check that file exists
if (!file.exists()) {
System.out.println("No such file");
System.exit(0);
}


try{

//create new Input Stream
fileIn = new BufferedInputStream(new FileInputStream(file));

}catch(IOException eee) {System.out.println("Problem creating File"); }

try{
//Create InetAddress
InetAddress theAddress = InetAddress.getByName(host);

try{

System.out.println("Creating Socket");
//Open the Socket
Socket s = new Socket(theAddress, port);
System.out.println("Created Socket");

//Create the output stream to the socket
out = new BufferedOutputStream(s.getOutputStream());

//creates a new buffer byte array
byte[] buffer = new byte[1024];
int numRead;


/////////////////////////////////////////////////////////
//numRead will equal bytes read by fileIn.  When there 
//are no more bytes to be read, numRead will equal 0
//and the while loop will end
/////////////////////////////////////////////////////////
while( (numRead = fileIn.read(buffer)) >= 0) {

//write the bytes to the output stream from 0 to total bytes
System.out.println("Writing the File to the out stream");
out.write(buffer, 0, numRead);

}

//flush the output stream
out.flush();
//close the output stream
out.close();
//close the input stream
fileIn.close();
//close the socket
s.close();

System.out.println("File Copy Completed");
}
catch (IOException e) {
}

}catch(UnknownHostException e) {
System.err.println(e);
}

}
}

And now the Server

///////////////////////////////////////////////////////////
//Server.java
//Usage:  java Server port
///////////////////////////////////////////////////////////
//imports
import java.net.*;
import java.io.*;
import java.util.Date;
import java.util.GregorianCalendar;
import java.util.SimpleTimeZone;
import java.util.Calendar;
public class Server {

//Main method
public static void main(String[] args) {

//get port from command line and parse from String to int
int port = Integer.parseInt(args[0]);


try{

//Create a Server Socket
ServerSocket server = new ServerSocket(port);

//Create a Socket
Socket connection = null;
Socket connection1 = null;

while (true) {

try{

//Set connection Socket = to incomming socket from client
connection = server.accept();
System.out.println("Server accept");


//Create the streams
BufferedInputStream in = new BufferedInputStream(connection.getInputStream());
BufferedOutputStream out = new BufferedOutputStream(new FileOutputStream(new File("ben.jpg")));
//Create a buffer byte array
byte[] buff = new byte[1024];
int readMe;

//set Begin transfer date
Date begin = new Date();
System.out.println("Started Transfer at: " + begin.toString());
/////////////////////////////////////////////////////////
//readMe will equal bytes read by in.  When there 
//are no more bytes to be read, readMe will equal 0
//and the while loop will end
/////////////////////////////////////////////////////////
while( (readMe = in.read(buff)) >= 0) {

//write the file out to disk from the input stream
out.write(buff, 0, readMe);


}

//Create End transfer date
Date end = new Date();
System.out.println("Ended Transfer at " + end.toString());
long msecs = begin.getTime() - end.getTime();
// Create a GregorianCalendar and set its time zone to GMT
GregorianCalendar delta = new GregorianCalendar(
new SimpleTimeZone(0, ""));
// Set the calendar's time to the difference between the two
delta.setTime(new Date(Math.abs(msecs)));
// The "base" year is 1970, so subtract that number
System.out.println("Years: " +(delta.get(Calendar.YEAR) - 1970));
System.out.println("Months: " + delta.get(Calendar.MONTH));
// The "base" date is 1, so subtract that number
System.out.println("Days: " + (delta.get(Calendar.DATE) - 1));
System.out.println("Hours: " + delta.get(Calendar.HOUR));
System.out.println("Minutes: " + delta.get(Calendar.MINUTE));
System.out.println("Seconds: " + delta.get(Calendar.SECOND));
System.out.println("Milliseconds: " + delta.get(Calendar.MILLISECOND));

//Close the connection socket
connection.close();
//close the input stream
in.close();
//flush the output stream
out.flush();
//close the outpust stream
out.close();

System.out.println("I have recieved the File");
}catch(IOException e) {System.out.println("Exception " + e.getMessage());}
finally {
try {
if (connection != null) connection.close();
}catch(IOException e) {}
}
}
}catch(IOException e) {
System.err.println(e);
}


}
}

Thanks for any help. By the way, I would like to do this in relation to the code I have. I know that there is the sun.net.ftp package and it would probably do this method in some way, but I would prefer not to use that package.
Thanks again
