Did you download the dependent library?

Ant FTP Task:

Note: This task depends on external libraries not included in the Ant distribution. See Library Dependencies for more information.

[Kriss Reddy]

I am using Ant 1.6.2 and 'C:\apache-ant-1.6.2\lib' folder contains
"ant-commons-net.jar" file. I am not sure whether is this the dependant library file or not! If you know exactly which file is that let me know where to get it from.

Thanks for your reply.

[Carol Enderlin]

Use the Library Dependencies link in my last post! It links to the part of this part of the library dependencies:

commons-net.jar
ftp, rexec and telnet tasks
jakarta-oro 2.0.1 or later is required in any case together with commons-net.
For all users, a minimum version of commons-net of 1.2.2 is recommended. Earlier versions did not support autodetection of system type or had significant bugs.

On that page is a link to download commons-net.jar.

[Kriss Reddy]

Thanks a lot Carol Enderlin.

I got it goin!

Hi!
I get the same error, but I have both the "ant-apache-oro.jar" and the "ant-commons-net.jar" in my "ANT_HOME/lib". I downloaded and untared apache-ant-1.6.2-bin.tar.bz2 when I realized that the SuSE team had removed commons-net from the 9.2 version of ant. Is there any other reasons for this error than missing jar files?

I'm on a suse 9.2 with java version 1.4.2

The jars dependencies are jars that don't come with ant and don't start with "ant-".

They are listed on the Library Dependencies page. Search for ftp and be sure to get both jars.

jakarta-oro-x.jar
commons-net-x.jar

[Soren Edzen]

I'm not sure if this is what you ment, but I solved it like this:
I got the 2 jars "commons-net-1.3.0.jar" and "jakarta-oro-2.0.8.jar" and moved them to ANT_HOME/lib. In an attemt to avoid a possible conflict I moved the two jars "ant-commons-net.jar" and "ant-apache-oro.jar" out of this directory. And it still didn't work. It wasn't untill I moved the later files back into ANT_HOME/lib that it started to work. Am I right in assuming that the jars I thought was nessesary for the ftp-task to work is just some sort of wrappers for the real jars? If it is so then It's a it confusing.
Anyway, thank you very much for putting me in the right direction.

S�ren

[Carol Enderlin]

Sorry, didn't mean to imply that the ant- jars weren't needed, just that they come with ant and that the library dependencies are additional jars that need to be downloaded and added to the lib dir.

Glad to hear you got it working.
