File copy/move thru java

Question

Hi,
My code is something like this..
Which is trying to copy or move a file from one location to other.
Problem is I do not see the last modified date getting preserved,
in the copied file.
Why does this happen ? and how to preserve the last modified date
to copied file ?
File fTempRead = new File(fFrom.getAbsolutePath(), filename);       
File fTempWrite = new File(fTo.getAbsolutePath(), filename);
if (fTempRead.canRead()) {
            lastmodified = fTempRead.lastModified();
            fTempWrite.setLastModified(lastmodified);
            RandomAccessFile randomWrite = new RandomAccessFile(fTempWrite, Messages.getString("FileIOHandler.14")); //$NON-NLS-1$
                FileChannel fWriteChannel = randomWrite.getChannel();
                RandomAccessFile randomRead = new RandomAccessFile(fTempRead, Messages.getString("FileIOHandler.15")); //$NON-NLS-1$
                FileChannel fReadChannel = randomRead.getChannel();
                FileLock readLock = fReadChannel.lock(0,fTempRead.length(), false);
                FileLock writeLock = fWriteChannel.lock(0, fTempWrite.length(), false);
                long fLength = 0l;                                          
                byte by[] = new byte[1024];               
                int byteread = 0;                              
                while ((byteread = randomRead.read(by)) != -1)     {
                    randomWrite.write(by, 0, byteread);               
                readLock.release();
                writeLock.release();
                randomRead.close();                    
                randomWrite.close();
                if(move) {
                    boolean r = fTempRead.delete();
                if(!r) {
                    throw new FileMoveException(sb.toString());
        }

I'm not sure, but I would imagine that if you first setLastModified, and then write the file, the lastModified will be set again by the write.
Try calling setLastModified after you're done writing. (Not sure if you need to do it before or after close(). Try it each way.)
