[SOLVED] Delete remote Non Empty folders with Java & SFTP

Issue

I have a requirement to delete multiple non empty folders on multiple UNIX servers. I am looking to use something like Apache FileUtils, which allows non empty LOCAL folders to be deleted. Its just that my folders in this case are REMOTE. Do i have to first list all the files contained in each remote folder, deleting each file found in turn? Or... Is there a java SFTP/SSH client that exposes the functionality of FileUtils.deleteDirectory() for remote folder removal?

Solution

I'm not entirely sure if it has a native recursive delete() (this is trivial to implement yourself though) but jsch (http://www.jcraft.com/jsch/) is an awesome implementation that allows for sftp access. We use it all the time.

Example code for connection:

JSch jsch = new JSch();
Properties properties = new Properties();
properties.setProperty("StrictHostKeyChecking", "no");

if (privKeyFile != null)
    jsch.addIdentity(privKeyFile, password);

Session session = jsch.getSession(username, host, port);
session.setTimeout(timeout);
session.setConfig(properties);

if (proxy != null)
    session.setProxy(proxy);

if (privKeyFile == null && password != null)
    session.setPassword(password);

session.connect();

ChannelSftp channel = (ChannelSftp) session.openChannel("sftp");
channel.connect();

The channel has rm() and rmdir().
