Something like 

Runtime r = new Runtime();
String  sc = String.format("ssh -C -p9222 %s rdiff-backup -- server",
                           hostName);
r.exec("rdiff-backup",
       "--remote-schema",
       sc,
       "username@remoteserver::/path_to/filestobackup " +
       "/path_to/backedupfiles");

ought to work.
