Java SFTP Transfer Library [closed]

Question

I'm looking for a dead simple Java Library to use for SFTP file transfers. I don't need any other features beyond that.

I've tried Zehon's, but it's incredible naggy, and I think 8 jar files is a bit crazy for so little functionality as I require.

And the library have to be free (as in free beer), and preferable Open Source (not a requirement).

Thanks.

Edit : I'm going to keep my previous answer, as JSch is still used in many places, but if you need a better-documented library, you can use sshj. An example in how to use it to do sftp is :

SSHClient ssh = new SSHClient(); ssh.loadKnownHosts(); ssh.connect("host"); try {     ssh.authPassword("username", "password");     SFTPClient sftp = ssh.newSFTPClient();     try {         sftp.put(new FileSystemFile("/path/of/local/file"), "/path/of/ftp/file");     } finally {         sftp.close();     } } finally {     ssh.disconnect(); }

Using JSch (a java ssh lib, used by Ant for example), you could do something like that :

Session session = null; Channel channel = null; try {     JSch ssh = new JSch();     ssh.setKnownHosts("/path/of/known_hosts/file");     session = ssh.getSession("username", "host", 22);     session.setPassword("password");     session.connect();     channel = session.openChannel("sftp");     channel.connect();     ChannelSftp sftp = (ChannelSftp) channel;     sftp.put("/path/of/local/file", "/path/of/ftp/file"); } catch (JSchException e) {     e.printStackTrace(); } catch (SftpException e) {     e.printStackTrace(); } finally {     if (channel != null) {         channel.disconnect();     }     if (session != null) {         session.disconnect();     } } 

You can use JSch directly this way, or through Commons VFS, but then you'll have to have both commons vfs jar and jsch jar.
