From Glub Tech:
Secure FTP Bean is a Java library that allows a developer to incorporate Glub Tech's secure FTP technology in any Java application. We've had many requests to release a product that can do secure FTP and not be tied to a specific user interface (UI). That request has now been fulfilled. The library supports 128-bit encrypted FTP over SSL/TLS and can make both implicit and explicit SSL/TLS connections. It can handle both passive and active data transfers with or without data encryption.
