Problem with a proxy

I tried to see what request the proxy receives :
When i try connect out of the applet, the proxy receives a SOCKS request (and the connection success).
But the same code executed by the applet send a request on the port 21... So the proxy refused it.
How is it possible ?

Because i didn't found solution to my problem, i chose to not implement my program with an applet : i send simply the java program to the client and he executes it. It works.
But i think there is a compatibility problem between applet and edtftpj...
