My code

    <fail message="Build Abrted! Failed to find property:ftpRemoteFile" unless="ftpRemoteFile"/>
    <fail message="Build Abrted! Failed to find property:ftpLocalDir" unless="ftpLocalDir"/>

    <echo message="FTP getting '${ftpRemoteFile}' from '${ftpRemoteDir}' to '${ftpLocalDir}'"/>
    <ftp action="get"
          server="${ftpServerName}"
          userid="${ftpUser}"
          password="${ftpPassword}"
          verbose="true"
          remotedir="${ftpRemoteDir}"
          skipFailedTransfers="true">
        <fileset dir="${ftpLocalDir}">
            <include name="${ftpRemoteFile}"/>
        </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
