EJB and FTP

[John R Roberts]

Hi, is is possible to connect to an FTP server from within an App Server?
I have a session bean that calls a worker class to retrieve files via FTP but I keep getting the following exception

java.net.BindException: Cannot assign requested address: bind
at sun.nio.ch.Net.bind(Native Method)
at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:119)

at org.apache.commons.net.ftp.FTPClient._openDataConnection_(FTPClient.java:475)
at org.apache.commons.net.ftp.FTPClient.retrieveFileStream(FTPClient.java:1342)

I can run the same code outside the App server and it works fine.
we are using Jakarta Commons FTP library.

Suggestions are apprecriated.

from the error message looks like the process may not have permissions to bind to a local socket. try using passive mode instead. another good component can be found here
