Tim,
Actually, I think it is a reasonable question. Sun provides
a JNDI-over-LDAP implementation, and the question (to me)
was can such a beast be used in conjunction with an AppServer.
<vendor>
In the case of Borland AppServer, the answer is yes. In
fact, any proper JNDI SPI implementation can be used. By
default, we use the JNDI-over-CosNaming implementation provided
by Sun, which is not proprietary (any more than LDAP is).
</vendor>
I suspect the JNDI-over-LDAP implementation can be used with
other AppServers, unless the given AppServer requires some "back
door" interaction with the naming service, which would lock
a given AppServer to its particular JNDI implementation.
