So I am trying to make sftp connection via proxy host and port, but could
not able to do it
getConnectionTimeout() = 60 seconds
`
public Response validateWithMinaEngine(long partnerId,
SftpCredentials sftpCredentials) {
SshClient client = null;
ClientSession session = null;
SftpClient sftp = null;
try {
ProxyConfig proxyConfig = getProxyConfigMina(true);
client = createMinaClient(sftpCredentials, proxyConfig);
if (proxyConfig != null) {
client.setClientProxyConnector(new
HttpProxyConnector(proxyConfig.host, proxyConfig.port, getConnectionTimeout()));
}
client.start();
HostConfigEntry host = new HostConfigEntry(
"",
sftpCredentials.getHost(),
sftpCredentials.getPort(),
sftpCredentials.getUser()
);
session = client.connect(host).verify(getConnectionTimeout(),
TimeUnit.MILLISECONDS).getSession();
if (StringUtils.isNotEmpty(sftpCredentials.getPassword())) {
session.addPasswordIdentity(sftpCredentials.getPassword());
}
session.auth().verify(getConnectionTimeout(),
TimeUnit.MILLISECONDS);
sftp = SftpClientFactory.instance().createSftpClient(session);
String directory = sftpCredentials.getPathPrefix();
if (!directory.endsWith("/")) {
directory += "/";
}
sftp.stat(directory);
return Response.ok(Collections.singletonMap("valid",
true)).build();
} catch (IOException e) {
logger.error("MINA I/O exception",
PIILogMaskingUtils.maskExceptionPII(logger, e));
throw new
ExternalFileException(ExternalFileException.DATABUS_SFTP_FOLDER_ERROR);
} finally {
if (sftp != null) try { sftp.close(); } catch (Exception ignore)
{}

ignore) {}
