JSch: Transfer file between remote and local computers/machines/systems in Java

There are many ways to do this. One way is use JSch to open a SftpChannel between your local machine and remote machine. You can download JSch from its offical site: http://www.jcraft.com/jsch/

Following is an example of the code.

import com.jcraft.jsch.Channel;
import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.JSchException;
import com.jcraft.jsch.Session;
import com.jcraft.jsch.SftpException;


public class RemoteSftp {
    public static void main(String[] args){
        try{
            JSch jsch=new JSch();

            Session session = jsch.getSession("<username>","<host name or IP address>");
            session.setPassword("<password>");
            session.setConfig("StrictHostKeyChecking", "no");
            session.connect();

            Channel channel = session.openChannel("sftp");
            channel.connect();
            ChannelSftp sftpChannel = (ChannelSftp)channel;
       
            sftpChannel.get("<source file path/file name>", "<destination file path>");
            sftpChannel.put("<source file path/file name>", "<destination file path>");

            sftpChannel.disconnect();
            session.disconnect();
        }catch(JSchException e){
            e.printStackTrace();
        }catch(SftpException se){
            se.printStackTrace();
        }
    }
}
