gnu.hylafax implements the HylaFAX client network protocol in pure Java. With it, Java applications can access a HylaFAX server in various ways, such as queueing FAX jobs, checking server/job status, and retrieving FAX files. The gnu.hylafax distribution also includes gnu.inet.ftp, a pure Java implementation of FTP client protocol (RFC0959).
Guiftp is a simple FTP client using the GTK+ toolkit. It can actually connect to a remote host, and download and upload files and directories. It supports interrupted transfer and bookmarks, and you can do the usual operations like erase files and directories, create directories, and erase directories recursively on both the local and the remote computer.
iDropper is an application for creating FTP uploader client "droplets", which you can distribute to anyone you wish, or use on your own desktop. A droplet is a mini-application that sits on the computer desktop as an icon. Once a droplet is configured, FTP file transfer is accomplished simply by dragging files and folders onto the desktop icon. End users require no knowledge of FTP protocols, do not need to install and configure an FTP client, and never need to know your FTP login and password information.
iGetter is a full featured download manager and accelerator. It can greatly improve the speed of your downloads using segmented downloading. In addition, it allows auto-resume on broken downloads, queue filtering by various criteria, site exploration, searching of mirrors, integration with the FileAvenue.net Web service, CD burning, scheduling downloads for low traffic periods, auto-redial on broken connections, auto hang-up and shut down on completion, and much more.
