1. Are you sure you want to use SSL instead of TLS for the protocol?
2. Is it implicit or explicit?
3. Are you using the correct port? 990 is typical.

Here's how my implementation connects...

String protocol        = "TLS";    // SSL/TLS

FTPSClient ftpsClient = null;
if (implicit){
  ftpsClient = new FTPSClient(protocol,true);
}else{
  ftpsClient = new FTPSClient(protocol,false);
}
ftpsClient.connect(server,port);

If you don't set the KeyManager, your FTPSClient won't present a client
certificate for authentication.
If you don't set the TrustManager, your FTPSClient won't verify the server
you're connecting to.
