I use the following piece of code to upload a photo to a ftp host. But the photo seems to be corrupted after being uploaded: There are narrow gray lines at the bottom of the photo.
The size of gray lines could be decreased by decreasing the Buffer Size of the FTPClient object.
import java.io.File;
import java.io.FileInputStream;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.apache.commons.net.ftp.FTPClient;
import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.net.ftp.FTP;
import org.apache.commons.net.ftp.FTPReply;
import sun.misc.Cleaner;
public class FtpConnectDemo1 {
public static void main(String[] args) {
FTPClient client = new FTPClient();
try {
client.connect("ftp.ftpsite.com");
//
// When login success the login method returns true.
//
boolean login = client.login("[email protected]", "pass");
if (login) {
System.out.println("Login success...");
int replay = client.getReplyCode();
if (FTPReply.isPositiveCompletion(replay)) {
File file = new File("C:\\Users\\e.behravesh\\Pictures\\me2_rect.jpg");
FileInputStream input = new FileInputStream(file);
client.setFileType(FTP.BINARY_FILE_TYPE);
if (!client.storeFile(file.getName(), input)) {
System.out.println("upload failed!");
}
input.close();
}
//
// When logout success the logout method returns true.
//
boolean logout = client.logout();
if (logout) {
System.out.println("Logout from FTP server...");
}
} else {
System.out.println("Login fail...");
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
//
// Closes the connection to the FTP server
//
client.disconnect();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
Never ever heard of corruption of that type, but: are you uploading from behind a firewall? Try doing client.enterLocalPassiveMode();
before calling storeFile
.
