[Wrapper-user] Starting wrapper on reboot as user instead of root

[<mai...@st...>]

Does anyone know how to start a wrapper as a user from rc.local?
su user -c /home/path/to/tomcat/bin/tomcat start

I just get error with wrapper spitting out the commands it can utilize
start | stop | restart etc

The above does not work. However, this does:
su user -c /home/path/to/tomcat/bin/startup.sh

Any ideas?
