Help with change directory
I'm new to Apache Commons (3.0.1), and am writing a Java program to FTP a file on my local server to an FTP server on the same network.
First, I'd like to make sure that changeWorkingDirectory() changes the directory on the remote machine. It's not clear from the documentation.
The first thing hat happens is that the "Change Directory didn't work" prints out. but I don't know what went wrong. So, I'm trying to use getReply() for more information, but my program hangs on that line. I know this becuase the line before it prints, but not the line after it.
Here's a code snippet:
FTPClient ftp = new FTPClient();
ftp.connect (server);
// status checking here - print statements indicate that connect was successful
boolean OK = ftp.changeWorkingDirectory ("/tmp/dir_name");
if {OK} {
System.out.println ("Change directory worked");
} else {
System.out.println ("Change directory didn't work");
system.out.println ("The FTP Reply Code is");
reply = ftp.getReply(); // reply was defined as int before doing the connect previous to this
System.out.println (Reply);
}
Thanks for any help you can offer.

But don't bother - it's been fixed (website will sync in a few hours).

Thank you so much - the debugging line was exactly what I needed. I am now able to ftp away!

RE: [NET] Help with change directory
Posted by "Magid, J. (Joe)" <Jo...@us.ing.com>.
I'd also suggest doing a command line FTP connect and execute the change folder by hand to ensure that you are where you think you are when you connect - usually each login ID is assigned a particular folder location and you might not be where you think you are.
You also may not want to include the leading / in your cwd input parm. If you are trying to do a relative directory change folder then the leading / will be trying to change you to an absolute folder location from the top of the folder tree on the drive you are connecting to.
(And I'm not sure about the earlier advice about VFS - it's got lots of capabilities, but isn't anywhere near as straight forward to work with if you're not a pretty experienced Java person, as is the case for me!)

getReply() is intended for low-level programming; it fetches the response from the server, so no wonder the code hangs.
You need to use getReplyCode() and/or getReplyString().
Have a look at the FTPClientExample code.

Re: [NET] Help with change directory
Posted by Diane Baumgartner <po...@yahoo.com>.
Thanks for your reply,
I'll retest, but I believe that previous versions of the code also hung on getReplyString and getReplyCode after the change directory.
Is it OK to use getReplyCode followed by getReplyString to output both the code and description?
Also, by FTPClient example code, do you mean the examples in the JavaDoc, or are there examples somewhere else I haven't found yet?
PS - I also tried to go to the FAQ linked to by the NET main page, but it was a bad link. Is there a specific place to report stuff like that?
Thanks again for your help.
