Error when connecting to FTP using apache commons

I am using apache common library for connecting to FTP with Android app.
Now I want to upload a file from internal storage to FTP server and I get this reply from getReplyString() method.
And I get this msg
553 Can't open that file: Permission denied
//Write file to the internal storage
String path = "/sdcard/";
File file = new File(path, fileName);
FileOutputStream stream = null;
try {
stream = new FileOutputStream(file);
stream.write(jsonObject.toString().getBytes());
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
stream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
// Read the file from resources folder.
try {
File file1 = new File(path, fileName);
Log.d("path",file1.getPath());
BufferedInputStream in = new BufferedInputStream (new FileInputStream (file1.getPath()));
client.connect(FTPHost);
client.login(FTPUserName, FTPPassword);
client.enterLocalPassiveMode();
client.setFileType(FTP.BINARY_FILE_TYPE);
// Store file to server
Log.d("reply",client.getReplyString());
boolean res = client.storeFile("/"+fileName, in);
Log.d("reply",client.getReplyString());
Log.d("result",res+"");
client.logout();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
client.disconnect();

fetch data from ftp://ftp.funet.fi/pub/mirrors/ftp.imdb.com/pub/ using java

how can I fetch movie.list.gz folder from the link
1: ftp://ftp.funet.fi/pub/mirrors/ftp.imdb.com/pub/, I have used a code to access the FTP server for fetching data but it asks for port no. which I don't know. Can anyone please tell how to fetch data from the above link in java. I am developing a Web Application which will display all the movie names present in IMDB database.
CODE:
String server = "ftp://ftp.funet.fi/pub/mirrors/ftp.imdb.com";
int port = 21;
FTPClient ftpClient = new FTPClient();
try {
ftpClient.connect(server);
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
// APPROACH #1: using retrieveFile(String, OutputStream)
String remoteFile1 = "/pub/movie.list.gz";
File downloadFile1 = new File("F:/softwares/mov.list.gz");
OutputStream outputStream1 = new BufferedOutputStream(new FileOutputStream(downloadFile1));
boolean success = ftpClient.retrieveFile(remoteFile1, outputStream1);
outputStream1.close();
if (success) {
System.out.println("File #1 has been downloaded successfully.");
}
} catch (IOException ex) {
System.out.println("Error: " + ex.getMessage());
ex.printStackTrace();
} finally {
try {
if (ftpClient.isConnected()) {
ftpClient.logout();
ftpClient.disconnect();
}
} catch (IOException ex) {

FTP file successfully transferred but is not true

Here is my simple code:
public boolean sendCSV() throws IOException {
System.out.println("Translating from xls to csv...");
File xls = new File("file.xls");
File csvFile;
csvFile = CSVManager.xlsToCsv(xls);
csvFile.renameTo(new File("file.csv"));
FTPClient client = new FTPClient();
FileInputStream fis = null;
try {
System.out.println("Establishing connection...");
client.connect(ftpHost, ftpPort);
System.out.print(client.getReplyString());
System.out.println("Connection ok.");
if (client.login(ftpUser, ftpPass)) {
System.out.println("Login ok");
System.out.print(client.getReplyString());
System.out.println("Setting PASV");
client.enterLocalPassiveMode();
System.out.print(client.getReplyString());
if (client.changeWorkingDirectory("/MYDIR")) {
System.out.println("Dir changed");
System.out.print(client.getReplyString());
} else {
System.out.println("Error changing dir");
System.out.print(client.getReplyString());
}
String filename = csvFile.getName();
TrayIconManager.SwitchTrayToFull();
fis = new FileInputStream(filename);
if (client.storeFile(filename, fis)) {
System.out.println("File sent");
System.out.print(client.getReplyString());
} else {
System.out.println("Error during sending file");
System.out.print(client.getReplyString());
}
}
if (client.logout()) {
System.out.println("Logout ok");
System.out.print(client.getReplyString());
return true;
} else {
System.out.println("Logout problem");
System.out.print(client.getReplyString());
return false;
}
} catch (IOException e) {
e.printStackTrace();
return false;
} finally {
try {
if (fis != null) {
fis.close();
}
client.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
}
}
What is the problem? The output says that
File sent
226-29 Kbytes used (0%) - authorized: 512000 Kb
226-File successfully transferred
226 0.343 seconds (measured here), 30.59 Kbytes per second
but is not true, because once I check on the ftp server the file is not there!
Why Kbytes used is 0%? Maybe is that the error?
The code seems to be ok, also the output.
So what is the real problem?

DebugException in apache-commons-net

When i try to list files from my location using ftpClient.listFiles("folder"); it shows
org.eclipse.debug.core.DebugException: com.sun.jdi.ClassNotLoadedException: Type has not been loaded occurred while retrieving component type of array.
Can some one guide me what i am doing wrong.
I use apache-commons-net-3.3
My code is
FTPClientConfig ftpClientConfig = new FTPClientConfig(FTPClientConfig.SYST_NT);
FTPClient ftpClient = new FTPClient();
ftpClient.configure(ftpClientConfig);
ftpClient.connect(hostName, Integer.valueOf(portNumber));
ftpClient.enterLocalPassiveMode();
ftpClient.login(username, password);
// Error throws here
FTPFile[] files = ftpClient.listFiles("folder");

This Exception is thrown when a user gave a Wrong or Encrypted Username Or Password.
Apache is not throwing the correct exception.

public void ConnectToFtp(String serverAdd,String username,String password){
try {
ftpclient.connect(serverAdd);
boolean login = ftpclient.login(username,password);
reply = ftpclient.getReplyCode();
if(FTPReply.isPositiveCompletion(reply)){
System.out.println("Connected Success");
}else {
System.out.println("Connection Failed");
ftpclient.disconnect();
}
if (login) {
System.out.println("Connection established...");
FTPFile[] ftpFiles = ftpclient.listFiles();
for (FTPFile ftpFile : ftpFiles) {
if (ftpFile.getType() == FTPFile.DIRECTORY_TYPE) {
System.out.printf("FTPFile: %s; %s%n",
ftpFile.getName(),
FileUtils.byteCountToDisplaySize(ftpFile.getSize()));
}
}
}
boolean logout = ftpclient.logout();
if (logout) {
System.out.println("Connection close...");
} else {
System.out.println("Connection fail...");
}
} catch (SocketException ex) {
ex.printStackTrace();
} catch (IOException ex) {
ex.printStackTrace();
} finally {
try {
ftpclient.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
