Solution 1
This worked for me.
JSch jsch = new JSch();
java.util.Properties config = new java.util.Properties();
Session session = jsch.getSession(RemoteUserName, RemoteIpAddr, RemotePortNo);
session.setPassword(RemotePassword);
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.setProxy(new ProxyHTTP(ProxyName, ProxyPort));
session.connect();
Solution 2
This Worked for me
ProxyHTTP proxy = new ProxyHTTP("192.168.10.1",80)

I want to transfer files to a remote location and I am bound to use a proxy server for that. I was able to connect to the FTP location via following command :
sftp -o "ProxyCommand /usr/bin/nc -X connect -x <proxy_host>:<proxy_port> %h %p" username@ftp_server:
But I want to automate this process of file transfer and I am using JSch for SFTP and snippet of code is below:
String sourceFile = sourceDir + fileName; JSch jsch = new JSch(); int port = Integer.parseInt(getFtpPort()); Session session = jsch.getSession(getUserName(), getHost(), port); session.setConfig(STRICT_HOST_CHECKING, ANSWER); session.setProxy(new ProxyHTTP(<proxy_host>, <proxy_port>)); session.setPassword(getPassword()); session.connect(); Channel channel = session.openChannel(FILE_PROTOCOL); channel.connect(); sftpChannel = (ChannelSftp) channel; sftpChannel.cd(desDir); File fileToTransfer = new File(sourceFile); sftpChannel.put(new FileInputStream(fileToTransfer), fileName);
With above code I am getting following exception:
Caused by: com.jcraft.jsch.JSchException: ProxyHTTP: java.io.IOException at com.jcraft.jsch.ProxyHTTP.connect(ProxyHTTP.java:158) at com.jcraft.jsch.Session.connect(Session.java:210) at com.jcraft.jsch.Session.connect(Session.java:162)
