What options are available to you to determine if the daemon is ready?
For example, does it create a lock file? If so, you could modify your
tomcat startup script in /etc/init.d, the one that calls
/usr/local/tomcat/bin/startup.sh, and have it check if the daemon is
ready and wait until it is, then when it is proceed and start tomcat.
For example, here's a little /bin/sh script that waits for the file
/bin/zzz to be created and sleeps 5 seconds and keeps checking:
while test ! -f /tmp/zzz
do
echo "sleeping for 5 seconds"
/bin/sleep 5
done
echo "here we go"

I am using Tomcat6.0.14 with Jdk1.6 on Linux RH4.
My application comprises a daemon and Tomcat6. The daemon is slow in
starting up. I need Tomcat6 to be started after the daemon is operational.
While the daemon is a Java application, its a third-party tool whose src I
do not control.
Is there any mechanism within Tomcat configuration by which I could
implement this "chaining" or synchronization such that catalina.sh starts
Tomcat VM after the daemon is somehow determined to be active?
