need help for smartftp in ssh tunnel plus http tunnel

in my case

side A :
workstation w/ (ssh client + smartftp client)

side B :
server w/ (ssh server + guildftpd server)

given only outgoing http connection is allowed at side A and a http tunnel
is established

i can successfully set up ssh tunnel already

my question is : is it possible to do FTP in this environment? what's the
required setting?
