J2SSH is an object-orientated Java implementation of the SSH version 2 protocol.

J2SSH is an object-orientated Java implementation of the SSH version 2 protocol. It provides a rich, powerful, and extensible SSH API that enables developers to gain access to SSH servers and to develop entire SSH client/server frameworks. The API library provides a fully-featured SSH2 implementation specifically designed for cross-platform development. Higher level components, representing both the standard SSH client and SSH servers, are provided which implement the protocol specification for user sessions and port forwarding. The specification currently supports public key and password authentication and a full implementation of the SFTP protocol.
