I have Java code that connects to an FTP server and downloads files. If the file name contains Arabic letters, then it always fails to download. But if it's English, it downloads successfully.
This is my code.
If the path is like this then it fails to download:
String actualFileLocation =
"/RelatedDocumentUploads\\...\\2017-S2\\تقرير الربع الرابع تقرير 2017 (006)senton(18-01-2017).pdf" ;
But if it's like the following it works fine:
String actualFileLocation =
"/RelatedDocumentUploads\\...\\2017-S2\\RCJY O5.K2 -D6(Q4) 2017-Doc 1.JPG" ;
The rest of the code:
int index = actualFileLocation.lastIndexOf("\\");
int extIndex = actualFileLocation.lastIndexOf(".");
String fileName = actualFileLocation.substring(index + 1, extIndex);
String extensn = actualFileLocation.substring(extIndex, actualFileLocation.length());
File parent = new File(System.getProperty("java.io.tmpdir"));
File tempFile = new File(parent, fileName + extensn);
tempFile.createNewFile();
OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(tempFile));
boolean success = ftpClient.retrieveFile(actualFileLocation, outputStream);
FTP client is from type : public class org.apache.commons.net.ftp.FTPClient
What's is wrong with my code?
This is the output of the of the log:

And this is the log from WinSCP client, which downloads the file successfully:

And this is the code that initializes the connection to the FTP server:
logger.info("Creating the ftp connection using the details");
String ftpServerAddress = wccInstanceDetails.get("ftpServer");
String ftpPort = wccInstanceDetails.get("ftpPort");
String ftpUserName = wccInstanceDetails.get("ftpUser");
String ftpPassword = wccInstanceDetails.get("ftppassword");
FTPClient ftpClient = new FTPClient();
try {
//added here
ftpClient.setAutodetectUTF8(true);
ftpClient.connect(ftpServerAddress, Integer.parseInt(ftpPort));
ftpClient.login(ftpUserName, ftpPassword);
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTP.ASCII_FILE_TYPE);
} catch (IOException ex) {
logger.error("Error occurs while creating the FTP connection : " + ex.getMessage());
}
return ftpClient;
After adding the setautodetectUTF(true), the output is changed, but the file is downloaded corrupted:

You may need to use UTF-8 encoding. First thing to try is to call FTPClient.setAutodetectUTF8:
ftpClient.setAutodetectUTF8(true);
(call that before connecting)
That should fix the problem your question is about.
Once you resolve the file name issue, you will need to fix transfer mode issue. You are transferring binary files (PDF) in text mode.
You need to use binary mode:
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
