I am trying to make a function in Java :

public static void upload_files(String us, String pw, String ip, String f){
 try
 {
    FTPClient client = new FTPClient();
    client.connect(ip);
    client.login(us,pw);
    client.upload(f);
 } catch(Exception e) {
    e.printStackTrace();
 }
}

I added apache libraries, but sadly I got an error on "upload" line I suppose I do not use correctly the method upload, but I don't know how to.

When I compile it with Netbeans, it is noticing me that there is an error line "client.upload(f);"

The error given in output is "java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: org.apache.commons.net.ftp.FTPClient.upload"

Thank you all in advance. nb : "f" is the direct path to my file

EDIT :

The problem is "quite" solved since now I upload some files on my ftp server BUT sadly they are all empty, as noticed on below.

The Apache FTPClient does not have an upload method.

What it does have, is a method called storeFile .

It takes as it's parameters the name the file should have on the server, and an InputStream. The InputStream reads from your local file, so you need:

 InputStream is = new FileInputStream( f );
 client.storeFile( some_name, is );

  • now I got the same error with "storeFile", ie "cannot find symbol" thanks to netbeans. And when I run it, this error appear: "java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: storeFile". – Dupond Durand Aug 08 '12 at 20:06
  • I don't think the error comes from netbeans. Here is the error after the compilation : " error: cannot find symbol storeFile("test1", is ); symbol: method storeFile(String,InputStream) location: class main 1 error" – Dupond Durand Aug 08 '12 at 20:17
  • I see. Indeed, now some file is uploaded. Sadly the file is totally empty, but my main point was resolved. No I am wondering why my txt file is not uploaded. But I will have some "test1.txt" uploaded on my ftp server. – Dupond Durand Aug 08 '12 at 20:31
  • Should I open a new topic for such a question ? Or may we continue here ? Because the file which is uploaded is completely empty (0 B). – Dupond Durand Aug 08 '12 at 20:39
  • You may have to call `flush` or `close` on the InputStream. The API documentation is [here](http://docs.oracle.com/javase/6/docs/api/java/io/InputStream.html). It may appear a bit intimidating if you're new to Java, but it's quite clear when you get used to it. – S.L. Barth is on codidact.com Aug 08 '12 at 20:40
  • I'm logging off now. I think you can find some answers by looking for code examples for FTPClient on the net, and in the FTPClient documentation. If that fails - "I get 0 bytes uploaded with FTPClient.storeFile" is, IMO, sufficiently different from your original question that you can post a new question. Good luck! – S.L.

  • I can imagine that it's clear when you're used to it, but as you noticed well, this is not my case, and I am a bit sorry about it. |||| After having checked I tried this code : InputStream is = new FileInputStream(f); client.storeFile("test1.txt", is ); is.close(); But sadly it didn't worked. Nothing was sent to the server now :/ – Dupond Durand Aug 08 '12 at 20:50
  • I just saw your answer about loggin off. Thank you for your help anyway. – Dupond Durand Aug 08 '12 at 20:54
