Just confirmed that the FTPS server is indeed working using Filezilla. Quite puzzled with this exception.
Code
FTPSClient client = null;
try {
client = new FTPSClient(protocol, isImpicit);
} catch (NoSuchAlgorithmException e1) {
// TODO Auto-generated catch block
Logger.debug(e1);
e1.printStackTrace();
}
client.setDataTimeout(timeoutInMillis);
//client.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));
System.out.println("################ Connecting to Server ################################");
try
{
int reply;
System.out.println("################ Connect Call ################################");
client.connect(ftpServer, ftpPort);
client.login(username, password);
System.out.println("################ Login Success ################################");
//client.setFileType(FTP.BINARY_FILE_TYPE);
client.setFileType(FTP.NON_PRINT_TEXT_FORMAT);
client.execPBSZ(0); // Set protection buffer size
client.execPROT("P"); // Set data channel protection to private
client.enterLocalPassiveMode();
System.out.println("Connected to " + server + ".");
reply = client.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply))
{
client.disconnect();
System.err.println("FTP server refused connection.");
System.exit(1);
}
client.listFiles();
//boolean retrieved = client.retrieveFile(remoteFile, new FileOutputStream(localFile));
}
catch (Exception e)
{
if (client.isConnected())
{
try
{
client.disconnect();
}
catch (IOException ex)
{
ex.printStackTrace();
}
}
System.err.println("Could not connect to server.");
e.printStackTrace();
return client;
}
finally
{
//client.disconnect();
try {
client.logout();
} catch (IOException e) {
// TODO Auto-generated catch block
Logger.debug(e);
e.printStackTrace();
}
System.out.println("# client disconnected");
}
return client;
