ftp in java, with jakarta commons net library file upload 1.4.1

Hello:

This is my code but it no runs..... i think that connect with the ftp but no transfer of files...

String server = "192.168.1.110";

String username = "joel";

String password = "123456";

String remote = "/privat/Joel/";

String local = "c:\\ftp.txt";

FTPClient ftp = new FTPClient();

//conectar al servidor and login

try

{

ftp.connect(server);

if(!ftp.login(username, password))

{

ftp.logout();

}

int reply = ftp.getReplyCode();

if (!FTPReply.isPositiveCompletion(reply))

ftp.disconnect();

InputStream in = new FileInputStream(local);

ftp.setFileType(ftp.BINARY_FILE_TYPE);

boolean Store = ftp.storeFile("/privat/public",in);

in.close();

ftp.logout();

ftp.disconnect();

ANY IDEA?

thanks

Based on your source I have just run this -

String server = "MY SERVER";

String username = "sabre";

String password = "my password";

String local = "/home/sabre/temp.txt";

FTPClient ftp = new FTPClient();

ftp.connect(server);

if(!ftp.login(username, password))

{

ftp.logout();

}

int reply = ftp.getReplyCode();

if (!FTPReply.isPositiveCompletion(reply))

ftp.disconnect();

InputStream in = new FileInputStream(local);

ftp.setFileType(ftp.BINARY_FILE_TYPE);

boolean Store = ftp.storeFile("fred.txt",in);

in.close();

ftp.logout();

ftp.disconnect();

and once I made sure my FTP server was running, my user name was correct, my password was correct and the source file existed then everything worked OK.

OK - so are yoou sure that file c:\ftp.txt exists?

It is the name of the file that will be stored in the root of the directory associated with your ftp login on the ftp server.

Are you sure you have an FTP server running?

sorry...but what common net library file upload do you use?I use common net library 1.4.1 but if you use source distribution, how do you install source distribution?

joeleta at 2007-7-14 19:10:41 >

# 7

yes, the file exists.

When i open the backup manually this contains four folders, and i haven't got privileges in three folder. I have to enter in one folder and copy the file there.

Do you understand me?

connection.changeWorkingDirectory(ftp:\\backup\public);

connection.changeWorkingDirectory(\public);

backup is then name of the backup

thanks

I use the 1.4.1 binary distribution.

You don't need to install the source though the examples that come with the source are usefull as templates to se ehow to use the package.

I think you probably need just

tp.changeWorkingDirectory("public"));

but make sure you test the return code e.g.

if (ftp.changeWorkingDirectory("public"))

{

// Changed OK

}

sabre150a at 2007-7-14 19:10:41 >

# 11

if (ftp.changeWorkingDirectory("public"))

{

JOptionPane.showConfirmDialog(null,"change");

}

I do this, and it confirmate that change the file, but don't store the file....

i don't know the problem.....

any idea?

MY CODE:

String server = "MYSERVER";

String username = "joel";

String password = "123456";

String local = "c:/ftp.txt";

FTPClient ftp = new FTPClient();

ftp.connect(server);

boolean login = ftp.login(username, password);

int reply = ftp.getReplyCode();

if (!FTPReply.isPositiveCompletion(reply))

ftp.disconnect();

ftp.setFileType(ftp.ASCII_FILE_TYPE);

boolean uno = ftp.changeToParentDirectory();

boolean dos = ftp.changeWorkingDirectory("public");

if (ftp.changeWorkingDirectory("public"))

{

JOptionPane.showConfirmDialog(null,"change");

}

boolean conectat = ftp.isConnected();

InputStream in = new FileInputStream(local);

//ftp.setFileType(ftp.BINARY_FILE_TYPE);

boolean Store = ftp.storeFile("ftp.txt",in);

in.close();

ftp.logout();

ftp.disconnect();

ALL THE BOOLEANS BE TRUE, FOR EXAMPLE UNO, DOS ARE TRUE.

can you speak spanish?

thankssss a lot

What happens when you use a standard command line or graphical client to connect and transfer files to your FTP server? Do the files end up where you expect?

# 14

i don't know if i understand your question, sorry but i'm spanish amb my english....isn't very well.. jeje, but a lot of thanks for your help.

when I debug the code, the code stop to

boolean Store = ftp.storeFile("ftp.txt",in);

and don't continue.

I'm sure that the ftp is running, the password and the user correct.

Thanks sabre for your valous help

You are CDing twice, did you mean to.

What does you catch clause look like?

# 16

I don't understand when you tell me CDing twice, what is the meaning?I haven't got catch, my catch iscatch (Exception e){;} thanksss

joeleta at 2007-7-21 9:50:26 >

# 17

okokok, now i understand.

boolean dos = ftp.changeWorkingDirectory("public");

if (ftp.changeWorkingDirectory("public"))

{

JOptionPane.showConfirmDialog(null,"change");

}

this isn't correct,

this yes

boolean dos = ftp.changeWorkingDirectory("public");

Swallowing exceptions like this is a sure way to waste time and is generally regarded as criminal. You almost certainly have an exception being throwns but unless you print a stack trace you will never know which one.

Post the full text of the stack trace and indicate which line of your source throws the exception.

yes it is the correct line, i'm surereally thanks

I agree with Sabre, you should use a smaller application to test.

Say:

import org.apache.commons.net.ftp.*;

import java.io.*;

public class Test {

public static void main(String[] args) throws Throwable {

String server = "192.168.1.110";

String username = "joel";

String password = "123456";

String remote = "/privat/Joel/";

String local = "c:\\ftp.txt";

FTPClient ftp = new FTPClient();

//conectar al servidor and login

try

{

System.out.println( "Connecting" );

ftp.connect(server);

if(!ftp.login(username, password))

{

System.out.println( "Login failed" );

ftp.logout();

return;

}

int reply = ftp.getReplyCode();

System.out.println( "Connect returned: " + reply );

if (!FTPReply.isPositiveCompletion(reply)) {

ftp.disconnect();

System.out.println( "Connection failed" );

return;

}

InputStream in = new FileInputStream(local);

ftp.setFileType(ftp.BINARY_FILE_TYPE);

System.out.println( "Downloading File" );

boolean store = ftp.storeFile("/privat/public",in);

in.close();

ftp.logout();

ftp.disconnect();

}

ok, i will try it

joeleta at 2007-7-21 9:50:26 >

# 29

I think I have worked out your problem. The default is to send your commands on port 21 and your data on port 22 but many systems (and firewalls) won't allow you to send data using this port which means you are not allowed to bind to port 22. It is normal to place the server PASV mode. This is achieved by using

ftp.pasv();

Add this just before you send the file and check the return code.
