Hi Heshan,

You can either do that (tell VFS where the know-hosts file is):
FileSystemOptions o = new FileSystemOptions ();
SftpFileSystemConfigBuilder.getInstance().setKnownHosts(o, new
File(myKnownHostsDir));
FileObject fo = VFS.getManager().resolveFile(myURI, o);

or tell it to ignore strict host key checking:
FileSystemOptions o = new FileSystemOptions ();
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(o, "no");
FileObject fo = VFS.getManager().resolveFile(myURI, o);

see http://commons.apache.org/vfs/apidocs/index.html

Cheers,

Steve
