Answer 1

I haven't used FTPClient (assume you mean Apache Commons FTPClient but a quick browse of apidocs shows two errors in your use:

1. The parameter to connect is server name, not url: client.connect("sftp://something.com") should be client.connect("something.com")
2. If you are using sftp you have to use FTPSClient

Answer 2

If you're connecting to an Sftp you might need to add the appropriate certificates (public/private keys) to the JVM where the code is running. Try your code on a regular FTP connection first, if that works, but not the sftp connections, it's almost sure is because of that.
