[jboss-jira] [JBoss JIRA] Resolved: (JBESB-303) exception in helloworld_ftp_action

[Bruno Georges (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBESB-303?page=all ]

Bruno Georges resolved JBESB-303.
---------------------------------

    Resolution: Done

Simple error handling has been added. 
This error was reproducable only on one type of FTP server.
The exception message is caught and error is logged at debug level.
Other exception will be thrown as expected.
Files with restricitve permissions are still visible when issuing an NLST command.
These files will also be renamed to the error-suffix value despite the restrictive permissions, althought it is not posssible to 'GET' them [as expected].
Behavior seems to vary between Server implementations and OS.
