All Implemented Interfaces:: SftLibConstants

public class Sft
extends com.ssh.sft.SftBase

The Secure File Transfer service. The SFT service allows manipulation of files and directory hierarchies in remote hosts. The SSH Tectia Server needs to be running on the remote hosts, and the SSH Tectia Broker needs to be running on the local host under the same user ID as the Java process that uses the SFT Service.

Constructor Detail

Sft

public Sft()

Creates a new instance of the SFT service. It will be the same as calling Sft(null, null).

Sft

public Sft(String broker_addr,
           Authenticator authenticator)

Creates a new instance of the SFT service. The authenticator is used to authenticate new SSH connections that the service needs to open.
Parameters:: broker_addr - the broker_address to connect (set to null to connect to default broker); authenticator - the authenticator to use. In windows, if set to null, ssh-broker-gui will be the authenticator.

Method Detail

getLocation

public Location getLocation(URI uri)
                     throws SftException

Returns the Location of a given file. This call will open a Session if needed, (if there is a session already open to the same host, it will reuse that given session). If broker does not have a connection to the server, connects to the server first. In this case, the authenticator may be called before returning.

Parameters:: uri - the URI where the remote file is specified.
Returns:: the Location object of the remote file
Throws:: SftException

openFile

public File openFile(URI uri)
              throws SftException

Returns the File pointed by the URI. It is the same as calling 'getLocation(uri).getFile()'.

Parameters:: uri - the URI where the remote file is specified.
Returns:: the File who represents the remote file.
Throws:: SftException

openSession

public Session openSession(URI uri)
                    throws SftException

Opens a new SFTP session using the username, host and port specified in the URI. It does not reuse already existing SFTP sessions. If necessary, connects to the server first. In this case, the authenticator may be called before returning. It uses the broker_address and the authenticator providen to the constructor of the Sft.

Parameters:: uri - the URI where username, host and port is specified.
Returns:: the new SFTP Session.
Throws:: SftException

openLocalSession

public Session openLocalSession()
                         throws SftException

Opens an SFTP session to the local host as the current user. No authentication is required. It is the same as opening a session with an URI without specifying username, host and port.

Returns:: the new SFTP Session.
Throws:: SftException
