I'm trying to pull out the file through ftp within ant, it get hung with after printing "getting files", so I enabled debug in ant and my output is

My code

    <ftp action="get"

        <fileset dir="${ftpLocalDir}">

        </fileset>
    </ftp>

Note: Normal ftp is working fine. I'm using Linux 64bit, ant 1.6.5 and java 1.6.10

Looks like everything works fine until you actually try and retrieve the data. FTP uses two channels; one for control and one for data. This works out fine until a firewall denies the data connection. Passive mode attempts to work around this. Does your FTP library work have a 'passive mode', or 'PASV' option?

Ant FTP task has require dependencies, Libraries that must be on classpath for it to function properly. See link below,

http://ant.apache.org/manual/install.html#commons-net

To use the FTP task, you need jakarta-oro 2.0.8 or later, and commons-net
