Hi Alan,
Ah yes, I see - having looked over the API for System properties again,
and that for InitialContext, I agree with what you say.

(My recollection was that one could set this JNDI environment via the
System properties, but I now see it would be unreasonably tortuous to
try to set things up in this way, given the way the System properties
API is defined.)

Hmm. Post in haste, recant at leisure.

Regards, Neil
