Implementing Java FTP client tools with EDTFTPJ

EDTFTPJ is a Java FTP toolkit that is easy to use and feels more usable than Apache, but Apache is more flexible. EDTFTPJ is available in a variety of versions, Java,. NET, and JS. There is a free version for the Java version. I'm using the free version. The rest are commercial versions.

for development, download the free version of the development package first. Home: http://www.enterprisedt.com/Toolkit: Http://www.enterprisedt.com/products/edtftpj/download/edtftpj.zip At the moment, I'm using 2.03. Before developing the FTP client tool, take a look at its e-text development guide: first, development guide 1, in development, the most core API in two classes, respectively, is: filetransferclient  by building this object to be FTP file transfer. Support for "plain" FTP, i.e. RFC 959 ftp ftpclient  functionality and filetransferclient, have been deprecated. Support "plain" ftp, i.e. RFC 959 ftp  2, connect an FTP server  1), build filetransferclient object  filetransferclient FTP = New Filetransferclient ();  2), set remote host and user authentication  ftp.setremotehost (host);  ftp.setusername (username);  ftp.setpassword (password);  ftp.setremoteport (+);  ftp.settimeout (+);  3), log on to the server   Ftp.connect ();  4), close connection  ftp.disconnect (),  3, set more connection Properties  1), set automatic login   Ftp.getadvancedftpsettings (). Setautologin (false);  2), set transfer buffer  ftp.getadvancedsettings (). Settransferbuffersize (1024x768)  3), set the encoding used to get server-side information  ftp.getadvancedsettings (). setcontrolencoding ("GBK") ,  4), set the time interval for transport notifications  ftp.getadvancedsettings (). Settransfernotifyinterval (5000); 5), some other settings   Ftp.getadvancedftpsettings (). Setconnectmode (ftpconnectmode.active);  ftp.getadvancedftpsettings (). SetActiveportrange (61500, 61510);  ftp.getadvancedftpsettings (). Setconnectmode (FTPCONNECTMODE.PASV);  4, Change the current working directory 1), get the current FTP working directory  string directory = ftp.getremotedirectory (), 2), change the current working directory   Ftp.changedirectory (directory), 3), change the current working directory to its parent directory  ftp.changetoparentdirectory ();  5, upload and download, pause 1), upload  ftp.uploadfile (Java.lang.string localfilename, java.lang.String remotefilename) 2), download   Ftp.downloadfile (Java.lang.string localfilename, java.lang.String remotefilename) 3), suspend all transmissions   Ftp.cancelalltransfers ()   Of course, many of these methods have multiple, overloaded formats. A simple encapsulated JAVAFTP client tool is given below:  second, encapsulated client-side tools
