  1. Fixed bug on the getPassiveSocket method which pass incorrect server and port information when using the SocketOpener class for openning new socket.
  2. Fixed bug on the getDataSocket method where the ServerSocket is not closed when using active mode transfer. This may cause problem if there are too many ServerSocket opened.
  3. Fixed bug on most of the get/put file methods where the setTransferType is not enclosed in the "try" block.
  4. Fix bug on parsing DOS format list with name contains more than 1 space.
  5. Fix bug on parsing UNIX format list with the first word of the name is also contains in the date or size.

  1. Increase code efficiency for private method getBytes(BufferedInputStream, FtpObserver). This increase the of those get file methods that return a byte array or String.

  3. Added the SocketOpener class to deal with add timeout feature for openning Socket.
  4. Changed the way to get new Socket in ftpConnect and getPassiveSocket methods to support * the timeout feature if it is being set.

  2. Fixed bug on parsing list with file name contains more than 1 space.

version 1.4.1 - 19, May 2000

  1. Fixed bug on FtpListResult class.
  2. Fixed bug on dead lock may caused by active mode data transfer.

Package

There are five classes and one interface in the bean, all belong to the package "ftp", they are:

classes:

ftp.FtpBean
The main class which provide basic operation.
ftp.FtpException
The exception which will be threw for any non-successful operation (eg. you want to get a file from the server through ftp but the file doesn't exist or permission denied.).
ftp.FtpListResult
A class for parsing information from the result of ftp LIST command.
ftp.FtpBeanBeanInfo
Bean info class for FtpBean. This is only for some visual IDE (eg. IBM Visual Age) to better understand the bean.
ftp.FtpListResultBeanInfo
Bean info class for FtpListResult. This is only for some visual IDE (eg. IBM Visual Age) to better understand the bean.
ftp.FtpReplyResourceBundle
Resource bundle that contains valid reply code for various ftp commands.

interfaces:

ftp.FtpObserver
Classes that implement this inteface can have the ability to monitor the progress of some uploading and downloading process.

Features

  1. Connect to ftp host.
  2. Passive and active data transmission.
  3. File delete.
  4. File rename.
  5. Get and put ascii files.
  6. Get and put binary files.
  7. Get and put binary files with a restarting point.
  8. Get directory name (PWD).
  9. Change directory (CWD).
  10. Make directory.
  11. Remove directory.
  12. Set port number.
  13. Get port number.
  14. Get host name.
  15. Get remote system types
  16. Get user name.
  17. Get reply from server.
  18. Get reply message from server.
  19. Execute command via ftp.
  20. Thread safe.
  21. Parsing information from the LIST command including file name, file size, owner, group and permission.
  22. Monitor the uploading and downloading process of the bean.

Coming Goals

  1. Implement methods to handle ascii files but not use too many memory.
  2. File name filter for parsing list
  3. Server to server transmission.
  4. Maintain backward compability.

Requirment

JDK 1.1 compatible Java Virtual Machine.

Platform

It is written in pure Java. So it can be run on any supported platform.
