Client to Server upload: File size limit

Question

Hi,
I am utilising java sockets to set up 2 way communication between a client and server program.
I have successfully transferred files from the client to the server by writing/using the code shown below.
However I now wish to place a limit on the size of any file that a user can transfer
to the server. I think a file size limit of 1 megabyte would be ideal. Does anyone know a straightforward
way to implement this restriction (without having to perform major modification to the code below)?
Thanks for your help.
*****Extract from Client.java******
if (control.equals("2"))
     control="STOR";
     System.out.print("Enter relevant file name to be sent to server:");
     String nameOfFile = current.readLine(); //Read in the name of the file to be sent, store in a
addLog("File name to be sent to server: " +nameOfFile);
     if(checkExists(nameOfFile)) //Call the checkExists method to make sure the user is sending a
     infoOuputStream.writeUTF(control);
     infoOuputStream.writeUTF(nameOfFile); //write the file name out to the socket
     OutputStream out = projSocket.getOutputStream(); //open an output stream to send the data
     sendFile(nameOfFile,out);
     addLog("File has been sent to server " +nameOfFile );
     else
          System.out.println("Error: The file is invalid or does not exist");
          addLog(" The user has attempted to send a file that does not exist" +nameOfFile);
private static void sendFile ( String file, OutputStream output ) {
try {
          FileInputStream input = new FileInputStream ( file );
int value = input.read();
while ( value != -1 ) {
output.write ( value );
value = input.read();
output.flush();
catch ( Exception ex ) {
*****Extract from Server.java******
if (incoming.equals("STOR"))
          String filename = iStream.readUTF(); //read in the string object (filename)
          InputStream in = projSock.getInputStream();
          handleFile ( in, filename ); //read in the file itself
     addLog("File successfully sent to server: " +filename);  //Record the send event in the log file
          System.out.println("Send Operation Successful: " + filename);
private static void handleFile ( InputStream input, String file ) {
try {
          FileOutputStream output = new FileOutputStream ( file );
int value = input.read();
while ( value != -1 ) {
output.write ( value );
value = input.read();
output.flush();
catch ( Exception ex ) {

Thanks for the advice. Have it working perfectly nowGlad it helped. You have no idea how refreshing it is that you didn't respond with, "Can you send me the code?" Nice to see there are still folk posting here who can figure out how to make things work with just a pointer or two...
