I am working on a project that attempts to leverage the FTP capabilities of the Jakarta Commons Net package. The Net package was originally written by an outfit called ORO and most kindly donated to Jakarta for maintenance. When running an demo application I wrote with the Net package, I encountered an error that a class was not found – and it appears that you also need to have the Net package’s sister package, now called Jakarta Oro, in your application classpath.
There, now use this information.
