My java program uploads a zip file from my system to FTP server. uploadfile() is a function that contains the uploading code.
uploadfile("192.168.0.210","muruganp","vm4snk","/home/Admin/GATE521/LN_RB_Semivalid2junk/Output/"+date+"_RB1.zip","/fileserver/filesbackup/Emac/"+date+"_RB1.zip");
public static boolean uploadfile(String server,String username,String Password,String source_file_path,String dest_dir){
FTPClient ftp=new FTPClient();
try {
int reply;
ftp.connect(server);
ftp.login(username, Password);
System.out.println("Connected to " + server + ".");
System.out.print(ftp.getReplyString());
reply = ftp.getReplyCode();
if(!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
System.err.println("FTP server refused connection.");
return false;
}
System.out.println("FTP server connected.");
InputStream input= new FileInputStream(source_file_path);
ftp.storeFile(dest_dir, input);
System.out.println( ftp.getReplyString() );
input.close();
ftp.logout();
} catch(Exception e) {
System.out.println("err");
e.printStackTrace();
return false;
} finally {
if(ftp.isConnected()) {
try {
ftp.disconnect();
} catch(Exception ioe) {
}
}
}
return true;
}
The zip file that I do have in my system is perfect. But after uploading the same in the server location,downloading the same, and extracting the problem occurs. "The file is corrupt" says the error. What should I do to resolve this issue. Kindly advise on this.
I suspect the problem would be something like, transferring through ASCII mode. It should actually be transferred through binary mode as per this QUESTION. How to attain the same? Please advise.
