Auto starting Tomcat during boot?

[Nelson Yip]

Hi,
 
I've just installed Tomcat 4.0.1 on my Red Hat 7.2 Linux box.
Everything works fine but Tomcat won't auto start after a reboot.
 
I added a symbolic link to the Catalina.sh file in my rc3.d level.
 
ln -s /usr/local/bin/tomcat/bin/Catalina.sh S99tomcat
 
Am I doing something wrong?
 
Thanks
Nelson
