Update directory in Java application after change.

Question

I'm making an application that creates a file in a directory and then takes that file and converts it to a ISO. The problem I have is when I run this command
            try {
                String command = "mysqldump -u root " + db10 + " -r/data/backups/dbbackup/" + db10 + ".sql";
                Process process = Runtime.getRuntime().exec(command);
                FlushStream error = new FlushStream(process.getErrorStream());
                FlushStream output = new FlushStream(process.getInputStream());
                error.start();
                output.start();
                process.waitFor();
                process.destroy();
            } catch (InterruptedException ex) {
                Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
            } catch (IOException ex) {
        }It creates the file but, when I run this command:
        try {
            String command = "mkisofs -r -o /data/backups/images/" + backu1 + ".iso /data/backups/dbbackup/*";
            System.out.println(command);
            Process process1 = Runtime.getRuntime().exec(command);
            FlushStream error = new FlushStream(process1.getErrorStream());
            FlushStream output = new FlushStream(process1.getInputStream());
            error.start();
            output.start();
            process1.waitFor();
            process1.destroy();
        } catch (InterruptedException ex) {
            Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
        }It comes back with an error saying that there are no files in that directory but, there is. How do I get java to "refresh" the directory so that it sees the file.

Answer 1

I don't see any Java code that you've posted that looks in a directory.
My guess is that the programs you're exec'ing have a different working directory than you think they do, or they're writing files to different directory that the other one is reading from.
