Thanks Rusty. I was hoping for a 'Java' solution ( as in 'OS independent'). The daemon is a java application (actually the activemq JMS broker);
Is there a way for me to have org.apache.catalina.startup.Bootstrap block till it receives a JMS notification or some such? The desired startup sequence would be (chronologically): Time 0: Start activemq broker Time t1: Broker operational - open for service Time t1 + 1: Start tomcat6 Thanks, /U -------------- Original message ---------------------- From: Rusty Wright <rusty.wri...@gmail.com> > Too many bins; I meant /tmp/zzz (as it is in the script). > > Rusty Wright wrote: > > What options are available to you to determine if the daemon is ready? > > For example, does it create a lock file?
