On a basic LAMP stack, at least with our RHEL5/6 servers, we are able to apply rolling code-updates to our document management system across load-balanced web servers without killing users' connections (and possibly document downloads) by using apachectl graceful and apachectl graceful-stop. We're migrating to a Tomcat web server based application, and we'd like to have that sort of capability with our new system, but I cannot find any sort of equivalent functionality with tomcat6. Does such a capability exist with tomcat6?
Tomcat – Apache tomcat equivalent of apachectl graceful

There is no such feature for Tomcat.
Remember that Tomcat is an application server and not a web server and it needs to load things upon start and perhaps shut down things nicely upon shutdown.
