Re: how to determine if tomcat is running
hello, why not write a small servlet that returns some value. then, in the script, just try to fetch the URL corresponding to that servlet. if u come back with a value, it means that tomcat is running, else not. hope that helps parag.

Re: how to determine if tomcat is running
Have you tried 'man ps' on the systems in question to see what the options should be? --jeff - Original Message - From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: "Thomas Fischer" <[EMAIL PROTECTED]> Sent: Sunday, June 24, 2001 5:10 AM Subject: Re: how to determine if tomcat is running > thanks for your response, but this method is not working on all unix > systems because some of them only show .../java as result of the ps > command (even with the options you mentioned). > > does anybody know anything else how i can be sure if tomcat is running > or not??? > > thanks, > > thomas. > > Am Samstag, 23.

Re: how to determine if tomcat is running
If tomcat is running it will be listening on the ports specified in the Connectors in server.xml. These will show up as listening in netstat, can be queried with lsof or fuser. Even that is no guarantee that it is tomcat listening, but it would be fairly trivial to retrieve a test page via a perl script to verify if it is tomcat or not.

Re: how to determine if tomcat is running
thanks for your response, but this method is not working on all unix systems because some of them only show .../java as result of the ps command (even with the options you mentioned). does anybody know anything else how i can be sure if tomcat is running or not??? thanks, thomas.

Re: how to determine if tomcat is running
You should have a java process running 'org.apache.tomcat.startup.Tomcat' when Tomcat is running. For example, when I run the 'ps' command I see the following: /usr/local/java/IBMJava2-13/jre/bin/exe/java -Xms64M -Xmx128M -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol -Dtomcat.home=/usr/local/java/jakarta-tomcat-3.2.2 org.apache.tomcat.startup.Tomcat This is all on one line, of course, and I have to use 'ps awx --cols=250' (Linux) in order to see the entire command line. Hope this helps.

how to determine if tomcat is running
i'm writing a script (on a unix-system) which should do different tasks wether tomcat is running or not. to do so the script has to figure out the status of tomcat. most daemons use .pid-files or anything similar. but i found nothing for tomcat. i've looked all through the documentation but found nothing about the runtime status of tomcat. how can i find out if tomcat is already running? thanks for any responses, thomas.
