Class JschSession

  • All Implemented Interfaces:
    RemoteSession

    public class JschSession
    extends Object
    implements RemoteSession
    Run remote commands using Jsch.

    This class is the default session implementation using Jsch. Note that JschConfigSessionFactory is used to create the actual session passed to the constructor.

      • JschSession

        public JschSession​(com.jcraft.jsch.Session session,
                           URIish uri)
        Create a new session object by passing the real Jsch session and the URI information.
        Parameters:
        session - the real Jsch session created elsewhere.
        uri - the URI information for the remote connection

      • exec

        public Process exec​(String command,
                            int timeout)
                     throws IOException
        Description copied from interface: RemoteSession
        Generate a new remote process to execute the given command. This function should also start execution and may need to create the streams prior to execution.
        Specified by:
        exec in interface RemoteSession
        Parameters:
        command - command to execute
        timeout - timeout value, in seconds, for command execution
        Returns:
        a new remote process
        Throws:
        IOException - may be thrown in several cases. For example, on problems opening input or output streams or on problems connecting or communicating with the remote host. For the latter two cases, a TransportException may be thrown (a subclass of IOException).
      • getSftpChannel

        public com.jcraft.jsch.Channel getSftpChannel()
                                               throws com.jcraft.jsch.JSchException
        A kludge to allow TransportSftp to get an Sftp channel from Jsch. Ideally, this method would be generic, which would require implementing generic Sftp channel operations in the RemoteSession class.
        Returns:
        a channel suitable for Sftp operations.
        Throws:
        com.jcraft.jsch.JSchException - on problems getting the channel.
