How to import files into CVS repository?

[somebody]

I've tried numerous permutations of the following command
to import my java files in ~/java into the repository
in /usr/local/cvsroot.  I get an error each time.
Can someone please tell me the syntax to use to simply
import the files in ~/java to /usr/local/cvsroot, WITHOUT
using the $CVSROOT environment variable?

-Thanks

cvs -b java -d /usr/local/cvsroot import -m "My java junk"
