Thank you all for your help on this.
I seem to have it working now. There were two issues which I'll try to make
explicitly clear for the mail list archive and future reference:
1) The correct syntax for the first argument string for rebind is:
"rmi://host/name", whereas I had only "//host/name".
2) More interesting is that localhost does not work. Thus,
"rmi//127.0.0.1/HelloServer" does not work, nor does
"rmi//localhost/HelloServer".
I solved this second problem by putting my machine IP, nickname and complete
hostname in /etc/hosts. Thus,
"rmi//hostname/HelloServer" works fine, as does
"rmi//xxx.xxx.x.2/HelloServer".
I say 'works fine', by which I mean that naming binds the object without
complaint. I don't have it actually doing anything, yet, but I naively don't
anticipate any problems.
