Sounds similar to the mod_jk connector in apache to connect to
tomcat. When I had to deal with this I setup a dedicated apache
instance on each system running tomcat whose sole purpose for
existence was for testing that connector.
So say setup an apache instance on another port, and have it
direct all traffic back to mod_jserv, then hit the apache
instance with http. It's not perfect but at least for me apache
was a lot more stable than tomcat especially in such a basic
configuration, so it worked well as a way to test the health
of the mod_jk connector.
