Apache FtpServer

Apache FtpServer is a 100% Java-based, open-source FTP server designed to be portable, embeddable, and scalable. It supports standalone operation as a Windows service or Unix/Linux daemon, and can also be embedded into Java applications. Built on the Apache MINA asynchronous I/O framework, it offers high performance and supports integration with Spring and OSGi environments. FtpServer is also an FTP application platform, providing a Java API (Ftplet) for handling FTP events.
