Description

Hi,

I am getting the following error while trying to connect to the FTP (Explicit).

java.net.SocketException: Operation timed out: connect:could be due to invalid address.

I am facing this error when i am running the code from the client machine which is in different domain...If i run the same code in the domain where ftp exists..it works fine without any issue...below is my code and the trace log....Pls help.

FTPSClient client = new FTPSClient("TLS",false);
client.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));
boolean _ftp_login = false;

try {
String[] hname = ftpurl.split("//");
client.setAuthValue("TLS");
client.setRemoteVerificationEnabled(false);

client.connect("ftp.kotaklifeinsurance.com",22);

int reply = client.getReplyCode();
client.execPBSZ(0);
client.execPROT("P");

if (!FTPReply.isPositiveCompletion(reply))

{ client.disconnect(); System.out.println("openFTPClient(): FTP server refused connection."); throw new Exception("FTP server refused connection."); }

else {
try

{ _ftp_login = client.login(userID, password); }

catch (Exception e)

{ throw e; }

if (_ftp_login) {

client.enterLocalPassiveMode();

if (client.printWorkingDirectory() == null)
throw new Exception("Current working directory returned is null");

client.changeWorkingDirectory("/XYZ/");

fis = new FileInputStream(localfile);
ins = (InputStream)fis;

boolean flag = client.storeFile(filename,ins);
System.out.println("File saved to FTP : "+flag);
