Apache2, mod_jk2, Jetty on Linux Redhat 9

Apache2, mod_jk2, Jetty on Linux Redhat 9

I am running a load-balanced apache/jetty architecture using the mod_jk2
connector.  I have been able to successfully set this architecture up with two
Jetty instances on the same box as the apache server.  Now I am trying to
transfer one of the Jetty instances to a seperate Linux box.  This is where I
have reached my roadblock.

The apache front end can still successfully communicate with the first Jetty
instance running on the same box, but I get the following Java error (found
below) when apache tries to communicate with the second instance on the
seperate server:

Is it possoble to run an architecture like this with Apache, mod_jk2, and Jetty
?  If so, is there anything special that must be done to enable it ?
