From the JSch page:
JSch allows you to connect to an sshd server and use port forwarding, X11 forwarding, file transfer, etc., and you can integrate its functionality into your own Java programs. JSch is licensed under GNU LGPL.
JSch 0.0.9 was released. The freshmeat page says that this version added support for SSH2 through a SOCKS 5 proxy. Just a heads up for anyone looking to incorporate SSH tunneling into their projects. Requirements are JDK1.4+. Excellent project!
