editFTPj delete problems

Question

Hi,

I'm writing an application which has to delete a file on a remote server. The problem, which I can't seem to solve is the following: I have the name of the file stored in a variable called fileName (type String). The name stored in the variable is correct, i checked it and compared it to the actual file name on the server and it's ok. The problem is, that if I call the client.deleteFile(fileName) method like this, it doesn't work, but if i call it this way: client.deleteFile("thename.jpg") it works. And the string and the variable are the same... I don't know what could be wrong. Everything is fine with the connection, I'm able to upload the file and it all works fine except for this... I also thought maybe the problem was that I was in the wrong directory, but it's all fine.

Here's the code snippet:

//before this i set up the connection
ftpDelete.changeDirectory("dir1"); //my directory where file is located
String fileName = "file1.jpg"; //file name
//deleting
client.deleteFile(fileName); //this doesn't work but this does: client.deleteFile("file1.jpg");
//disconnect
client.disconnect();


And here's what I get as an output in the console:
SEVERE: null
com.enterprisedt.net.ftp.FTPException: 550 2011_00000001_RACUN.jpg : The system cannot find the path specified.

please, help, because it's driving me crazy...

Answer 1

Enable logging at DEBUG level - the output will tell you what command (including filename) is being sent to the server.

Answer 2

so i put logging in my code, and here's what I get:

The program connects to server correctly and also changes directories to get to the folder named 01, where the file 2011_00000000_RACUN.jpg is located... I can upload files to the server with no problems (i uploaded this particular .jpg file as well) and I checked my permissions and I have full control over all these folders. The name of the file is ok, so I really don't have any idea what is wrong. I hope I got logging right and that u can help me with this...

Answer 3

Could you also post the log of when it succeeds? It would also be useful to call dirDetails() prior to the delete so we can see the directory listing.

Answer 4

here's the log when the file is deleted: (the name is a bit different, but 2011_00000001_RACUN and 2011_00000003_RACUN both exist in the same folder.

And here's what happens if i try to cal method directoryList("01"), where 01 is the folder with the .jpg files. That's how the call of the method looks like:
log.debug("dir. details:");
FTPFile[] directoryList = ftpDelete.directoryList(comCode);
log.debug("end of dir details");
log.debug("deleting.");
//sedaj smo v pravi mapi v kateri bomo pobrisali file z imenom imeScana
//ftpDelete.deleteFile(imeScana);
ftpDelete.deleteFile("2011_00000004_RACUN.jpg");
//na koncu se zapremo povezavo
ftpDelete.disconnect();
log.debug("deleted.");

and here's the log:
DEBUG [virtcomui.VirtcomGUIOsnova] 4 Nov 2011 21:29:49.600 : dir. details:

It obviously has some problems with the directoryList, since it doesn't come to the "end of dir details" part...

Answer 5

Just call dirDetails("") - you can't supply 01 as the parameter if you are already in that directory.

Answer 6

I don't have the method dirDetails(), so i called directoryList("") and here's the log:

If i print out the directory list that this method returns, it looks like this: - the list is ok.

Answer 7

There has to be something simple going on here but I can't see what it is. Post the output of this (using the filename/dir that fails):

client.changeDirectory("dir1");
String fileName = "file1.jpg";
try {
client.deleteFile(fileName);
}
catch (FTPException ex) {}
client.deleteFile("file1.jpg");
client.disconnect();

Answer 8

Here's what the code looks like now:
ftpDelete.changeDirectory(comCode); //comCode is my directory
log.debug("deleting.");
String filename = preberiPropertiesFile("scanName");
try{
ftpDelete.deleteFile(filename);
}
catch(FTPException ex){}
ftpDelete.deleteFile(filename);
ftpDelete.disconnect();

And here's the log:

I'm reading filename from a .properties file, if that could maybe cause problems?? But then I also read directoryName (comCode) from properties and it works fine...

Answer 9

Please put the filename explicitly the second time (the way you said it works). That way we will know what was sent to the server for the successful and failed deletes.
