This class implements a FTP client. You can use an instance of this class to connect to a remote FTP site and do FTP operations like directory listing, file upload and download, resume a broken upload/download and so on. The common flow is: create the object, connect to a remote FTP site with the connect() method, authenticate with login(), do anything you need with the contents of the remote site, quit the site with disconnect(). A FTPClient object can handle a connection per time. Once you have used and disconnected a FTPClient object you can use it again to connect another FTP server. @author Carlo Pelliccia @version 1.5

org.apache.commons.net.ftp.FTPClient
r connection attempt, you should check the reply code to verify // success. reply = ftp.getReplyCode(); if(!FTPReply.isPositiveCompletion(reply)) { ftp.disconnect(); System.err.println("FTP server refused connection."); System.exit(1); } } catch(IOException e) { if(ftp.isConnected()) { try { ftp.disconnect(); } catch(IOException f) { // do nothing } } System.err.println("Could not connect to server."); e.printStackTrace(); System.exit(1); }
Immediately after connecting is the only real time you need to check the reply code (because connect is of type void). The convention for all the FTP command methods in FTPClient is such that they either return a boolean value or some other value. The boolean methods return true on a successful completion reply from the FTP server and false on a reply resulting in an error condition or failure. The methods returning a value other than boolean return a value containing the higher level data produced by the FTP command, or null if a reply resulted in an error condition or failure. If you want to access the exact FTP reply code causing a success or failure, you must call getReplyCode after a success or failure.
The default settings for FTPClient are for it to use FTP.ASCII_FILE_TYPE , FTP.NON_PRINT_TEXT_FORMAT , FTP.STREAM_TRANSFER_MODE , and FTP.FILE_STRUCTURE . The only file types directly supported are FTP.ASCII_FILE_TYPE and FTP.IMAGE_FILE_TYPE (which is the same as FTP.BINARY_FILE_TYPE ). Because there are at lest 4 different EBCDIC encodings, we have opted not to provide direct support for EBCDIC. To transfer EBCDIC and other unsupported file types you must create your own filter InputStreams and OutputStreams and wrap them around the streams returned or required by the FTPClient methods. FTPClient uses the NetASCII filter streams in org.apache.commons.net.io to provide transparent handling of ASCII files. We will consider incorporating EBCDIC support if there is enough demand.
FTP.NON_PRINT_TEXT_FORMAT , FTP.STREAM_TRANSFER_MODE , and FTP.FILE_STRUCTURE are the only supported formats, transfer modes, and file structures.
Because the handling of sockets on different platforms can differ significantly, the FTPClient automatically issues a new PORT command prior to every transfer requiring that the server connect to the client's data port. This ensures identical problem-free behavior on Windows, Unix, and Macintosh platforms. Additionally, it relieves programmers from having to issue the PORT command themselves and dealing with platform dependent issues.
Additionally, for security purposes, all data connections to the client are verified to ensure that they originated from the intended party (host and port). If a data connection is initiated by an unexpected party, the command will close the socket and throw an IOException. You may disable this behavior with setRemoteVerificationEnabled().
You should keep in mind that the FTP server may choose to prematurely close a connection if the client has been idle for longer than a given time period (usually 900 seconds). The FTPClient class will detect a premature FTP server connection closing when it receives a FTPReply.SERVICE_NOT_AVAILABLE response to a command. When that occurs, the FTP class method encountering that reply will throw an FTPConnectionClosedException . FTPConnectionClosedException is a subclass of IOException and therefore need not be caught separately, but if you are going to catch it separately, its catch block must appear before the more general IOException catch block. When you encounter an FTPConnectionClosedException , you must disconnect the connection with disconnect() to properly clean up the system resources used by FTPClient. Before disconnecting, you may check the last reply code and text with getReplyCode , getReplyString , and getReplyStrings. You may avoid server disconnections while the client is idle by periodicaly sending NOOP commands to the server.
Rather than list it separately for each method, we mention here that every method communicating with the server and throwing an IOException can also throw a MalformedServerReplyException , which is a subclass of IOException. A MalformedServerReplyException will be thrown when the reply received from the server deviates enough from the protocol specification that it cannot be interpreted in a useful manner despite attempts to be as lenient as possible.
