i just upgraded to 1.5 from 1.4.6
Read the documentation
and changed the constructor into FTPClient() - no parameters since the others have been deprecated.
then set all the parameters (host, port, etc etc)
then used user() and password() - as the previous version, it didnt work.
then used login(us, pss) - as the previous version, it didnt work.
I think the documentation should mention we need to invoke connect() before login() or user() password().
Cause in the previous versions i could simply use login() or user()/password() and it was connecting to the server automatically.
just a suggestion
