An Applet That Breaks All The Rules.

Applets are not allowed to open files or network connections and they are not supposed to be multi threaded. Rad FTP does all that and more.

(PRWEB) February 4, 2004 --Java applets are not supposed to be multi-threaded. They are definitely not allowed to access local files or make network connections to remote servers. The Rad FTP applet breaks all these rules. Not only does it open files on your hard disk, it will then upload them to remote FTP servers. Worse still the applet will use multi-threading to upload several files concurrently.

The java virtual machine places applets in a 'sandbox' the local file system and remote networks lie outside this sandbox. These restrictions are enforced as protection against hackers with rogue applets gaining access to web user's computer.


These same restrictions also prevent java from being a popular choice for networking tasks such as FTP or telnet. Fortunately it's possible to move an applet out of it's sandbox with the use of digital signatures along with suitably adapted code. The File Transfer Program (FTP) by Rad Inks is such an applet that leaps out of the sandbox to read from and write to the user's hard disk.

The use of digital signatures is a perfectly legitimate method where the user himself can decide whether the applet should be allowed to 'break out' of the sandbox. Using the Rad FTP applet is safe since it is the user who decides what FTP server to connect to and what files should be uploaded.

Rad FTP is equipped with a rich graphical user interface. Since it makes use of multi threading the user can carry out several concurrent file transfers at a given moment. What is remarkable is that despite these features the FTP applet is just 72 Kilo Bytes in size. Other File Transfer Programs with similar features can be ten to fifteen times larger.

Rad Inks is an innovative software company located in Sri Lanka. They have a suite of products that complement the FTP applet with a web based print suite being the flagship product. Rad FTP is
