go read about LDAP, because LDAP was the prototype example, of a directory/naming service protocol, that JNDI was written for, I think.



And LDAP was a slightly sensible/ slightly sane simplification (hence "L" for "Lightweight"), for the Internet, of the original unwieldly impossible to implement + support "DAP".


And "DAP" was specified in spec # X.500, of the unwieldly bureaucratic OSI protocols of the ISO.


And OSI was basically the European telcom monopolies' attempt, in the late 1980's, to replace the Internet (since it was created by and controlled by the U.S. dept. of Defense) with their own system, under their exclusive control, including abominations like X.400 email systems, which basically were intended to sit atop of X.500 directory systems, and were also intended to use OSI transport protocols (TP4, etc.) instead of TCP/IP, etc. ....
