001 java.net. UnknownHostException ?

If like me, you have recently been having problems using ftp to send your blogger.com blog entries to your site and receive instead this error message:

001 java.net.UnknownHostException

you should check out this blogger forum thread: bizarre error message 001 java.net.UnknownHostException.

Basically, what you have to do is to find out the IP address of your ftp hostname, enter that in your blogger settings, republish, and you should be fine.
