Description Franck Perrin 2007-10-05 01:37:22 UTC 
I try to use the ftp task accessing an AIX 5.3 FTP server.
The server is in french language.
When I use the recentDateFormatConfig attribute, a NullPointerException is 
raised.
If I dont use it, nothing happens.
Here is the task I execute :
	<target name="listp114p06e">
		<ftp action="list"
			server="yyyyyy"
			userid="xxxxxx"
			password="zzzzzz"
			remotedir="Websphere/Envts/prod2/LogApps/Today"
			defaultDateFormatConfig="dd MMM yyyy"
			recentDateFormatConfig="dd MMM HH:mm"
			serverLanguageCodeConfig="fr"		             
			listing="list.txt">
			<fileset>
				<include name="**/*"/>
			</fileset>
		</ftp>
	</target>
Here the output in debug mode :

I installed the libraries commons-net-1.4.1.jar and jakarta-oro-2.0.8.jar in 
ANT_HOME/lib.

Here is what I get when I use the FTP commands :
ftp> cd Websphere/Envts/prod2/LogApps/Today

ftp> pwd

Thanks.
Comment 1 Franck Perrin 2007-10-09 14:04:53 UTC 
Actually, there is no bug.
The problem was the month abbreviations used on the server in file timestamp dates.
I resolved the problem, setting the shortMonthNamesConfig attribute to
"jan|f\u00e9v|mar|avr|mai|jun|jul|ao\u00fb|sep|oct|nov|d\u00e9c".
