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);
