I don't really understand what the issue is here, but I plead ignorance in that I haven't worked with the DJB tools in a while. But, as I recall, the tools simply execute the program using the (by default) 'run' script. When run exits, for whatever reason, the tools fire it back up. Now the tomcat startup scripts fire the java process off in the background, but as I recall there is an option to NOT do that, and simply have tomcat.sh stay in the foreground. It seems to me that a few simple tweaks to tomcat.sh, linked to 'run' in the "proper spot", and it should Just Work. Lemme look. "This man has a bad heart. Angina Pectoris, but we have the cure...Yes. Here they are..." Yes, here it is, just start catalina.sh with the "run" option, and it doesn't fork into the background. #!/bin/sh # daemontools run script for Tomcat cd /usr/local/java/jakarta-tomcat-4.0.4/bin # start tomcat in the foreground, redirect stderr to stdout for logging. exec ./catalina.sh run 2>&1 Copy or link this script to /services/tomcat/run, and it should fire right up. Untested, but it should work. Multilog should work with this as well, as the 'run' option doesn't redirect stdout or stderr, whereas the (default) 'start' option does. Since multilog only listens to stdin, the script redirects stderr to stdout so it can be captured as well. You need to setup the log directory properly, as mentioned in DJBs faq. The key is to keep the java process in the foreground for the 'run' script. supervise puts it in the background for you, so that's why the run script doesn't need to.
