User management is currently not supported when you get the repository
object through RMI. Try the same code getting the repository through Webdav:

Repository repository =
 JcrUtils.getRepository("http://localhost:8080/server<http://localhost/jackrabbit/server>
");

(check the parameter "http..." in Jackrabbit's documentation since did not
check it, but it should work like that).

Greetings!
