Yea, these options were in the mod_jk template that I started with.
It was left here by a previous administrator. I commented this out
and restarted apache, yet I get the same error.
I guess what I'm not clear on is how you replace mod_jserv's configuration:
ApJServMount /servlets ajpv12://host.domain.com:8008/root
with the equivalent version using JkMount.
