How to get the java home dir.

Includes classes to let  you copy, append (concatenate),
download and upload files from within a Java program.  Also
contains a command-line utility to download files.

Fully commented Java source is provided.  It is now comes in
four parts, MiniFileTransfer, FileTransfer and
MaxiFileTransfer, Download depending on how much
functionality you require.  Now supports copying members in
local jar files.

You use it in your own programs, typically something like this:

// test FileTranser.append
import com.mindprod.filetransfer.FileTransfer;
import java.io.File;
public class Concat
   {
   /**
    * test harness to concatenate c onto the end of b, leaving the result in a.
    *
    * @param args not used
    */
   public static void main ( String[] args )
      {
      File a = new File ("C:/temp/temp.txt");  // does not exist yet
      File b = new File ("E:/mindprod/feedback/peaceincorrect.html");
      File c = new File ("E:/mindprod/jgloss/j.html");

      FileTransfer ft = new FileTransfer ( 50000 /* buffsize */ );
      // source, target
      ft.append( b, a );
      ft.append( c, a );
      }
   }


Command line use:

java -jar download.jar http://x.com/anyfile.html  C:\temp\anyfile.txt

Usually you embed these classes in your own program rather
than using them standalone.
