ArrayIndexOutOfBoundsException at ftp_client.dirDetails(&quo

Question

Hello there,

if I'm listing directories with a large amount of files (here about 2000 files) by using

FTPFile[] files = ftp_client.dirDetails(".")

I get an ArrayIndexOutOfBoundsException =(

With smaller directories, there is no problem.

Someone has a suggestion to solve this?

Thank you

David

Hi there,

I've still got that problem:

 Here comes the directory listing.
DEBUG [com.enterprisedt.net.ftp.FTPControlSocket] 16 Jun 2004 09:47:19.500 : 226
 Directory send OK.

What operating system and FTP server are you using?

Ok, I think I see your problem. To test out a solution, can you try this?

Edit FTPFileParser.java, and change

private final static int MAX_FIELDS = 12;

to

private final static int MAX_FIELDS = 20;

Recompile and give it a go - this should sort your problem out (I hope!)

This fix is in 1.4.1, out now.

We've tried with a file of the same name, works fine.

Hi there

I am using version 1.4.3 and still am getting the IndexOutOfBoundsException and ParseException on dirDetails(). The server is a SunOS 5.8 with default FTP server. Any suggestions to try?

Thanks, Chris Schuit

Could you post a directory listing up here for us?

The directory structure on the Sun is:

-rw-rw-rw-   1 2960     100           26537 Sep  9 00:46 09064426507.req.copied
-rw-rw-rw-   2 2960     100          234092 Sep  9 01:07 09064426507.res

*snip*

There are over 1600 files in the directory, total of 192M. Might that be an issue?

Answer 8

Can you post the stacktrace and if possible the actual line of the listing where it falls over? Thanks - should have asked for this earlier. The number of files shouldn't be an issue.

Answer 9

The stack trace:

java.text.ParseException: Unexpected number of fields: 8
   at com.enterprisedt.net.ftp.UnixFileParser.parse(UnixFileParser.java:126)
   at com.enterprisedt.net.ftp.FTPFileFactory.parse(FTPFileFactory.java:159)
   at com.enterprisedt.net.ftp.FTPClient.dirDetails(FTPClient.java:1722)

I can't determine which line of the directory listing generates this error. If you have a way to test this, I'm all for it ;)

with a debugger you could maybe know for which file it occurs. or simply add a writeline of the current processed string ?

or you could send a zip file with "ls > output" content and then the support will have to recreate the dir with a "touch script" for e.g ...
