Using an example found in this forum as a program written by me I've discovered that don't work on remote files.
The program runs on NT and the file I want read is on a mapped network disk. Does anyone know why after reached the EOF the file seems not been updated?
Has anyone some suggestion?

Here the code I've used:

			import java.io.*;
			

			

			public class Tail {
			

			

			public Tail(File f) throws java.io.IOException, java.lang.InterruptedException{
			

			

			int pos = 0;
			

			RandomAccessFile file = new RandomAccessFile(f, "r");
			

			pos = (int)file.length() - (int)Math.min(400, file.length());
			

			file.seek(pos);
			

			for  (;true; Thread.currentThread().sleep(2000)){
			

			int l = (int)(file.length()-pos);
			

			if (l
			<= 0) continue;
			

			byte[] buf = new byte[l];
			

			int read = file.read(buf,0, l);
			

			String out = new String(buf, 0,l);
			

			System.out.print(out);
			

			pos = pos+l;
			

			

			}
			

			}
			

			

			public static void main(String[] args) {
			

			try{
			

			Tail tail1 = new Tail(new File(args[0]));
			

			}
			

			catch (ArrayIndexOutOfBoundsException a){
			

			System.out.println("Usage : Tail
			");
			

			System.exit(1);
			

			}
			

			catch (java.io.IOException io){
			

			System.err.println(io.getMessage());
			

			System.exit(1);
			

			}
			

			catch (Exception xe){
			

			xe.printStackTrace();
			

			System.exit(1);
			

			}
			

			}
			

			}
