Does Google App Engine support ftp ?

Question

Now I use my own Java FTP program to ftp objects from my PC to my ISP's website server.

I want to use Google App Engine's servlet to get Paypal IPN messages, then store the messages into my own objects and ftp the objects to my ISP's website server, is this doable ? I heard Google App Engine doesn't support FTP.

I don't expect Google to do it for me, but can I use my own Java FTP program in the web app that I upload onto the App Engine to do it ?

No, you can't open any socket connection except by using URL Fetch service on HTTP/HTTPS to these port ranges:

80-90, 440-450, 1024-65535.
