File Upload using SFTP

Question

I'm trying to upload a file to webapps folder of tomcat in my local system through the following code, also do we require any installations to be done before using this code

public class DeployManager {

public static void main(String[] args) {

    String SFTPHOST = "1.2.3.4";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "C:\\Program Files\\Apache Software Foundation\\Tomcat 8.0\\webapps\\";
    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        channel = session.openChannel("sftp");
        channel.connect();
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd("..");
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File("C:\\Users\\Jainesh_Trivedi\\Desktop\\WAR\\AutohostDemo1_1145.war");
        channelSftp.put(new FileInputStream(f), f.getName());
    } catch (Exception ex) {
        ex.printStackTrace();

    }
}}

but I'm getting the following error:

You need to make sure sftp running on the machine with IP "10.74.64.102" . I guess its your local windows machine .
