        byte buffer[] = new byte[BUFFER_SIZE];
        // Open archive file
        FileOutputStream stream = new FileOutputStream(archiveFile);

            System.out.println("Adding " + tobeJared[i].getName());

            // Add archive entry
            JarEntry jarAdd = new JarEntry(tobeJared[i].getName());
            jarAdd.setTime(tobeJared[i].lastModified());
            out.putNextEntry(jarAdd);

            // Write file to archive
            FileInputStream in = new FileInputStream(tobeJared[i]);
            while (true) {
                int nRead = in.read(buffer, 0, buffer.length);
                if (nRead <= 0)
                    break;
                out.write(buffer, 0, nRead);
            }

        out.close();
        stream.close();
