Well, in that case, I will include here the content of a message posted by
Tim Funk on 6/13/2002, which has his solution for this, which I find pretty
neat. Hopefully Tim doesn't mind, and I should add that this would break
portability, most notably on Windows machines.
On 6/13/2002, Tim Funk wrote:
For what its worth - I created (and use) a LifecycleListener that runs
on startup which logs the process ID into a file called tomcat.pid.
Which is created by a shell script called writepid.sh. Below is all the
code to get this to work. This code also assumes your current working
directory is $CATALINA_HOME.
--Begin code
import org.apache.catalina.LifecycleEvent;
/**
* A helper for getting the PID of java so shutting down tomcat is MUCH
* easier.
*/
public class PidLifeCycle implements org.apache.catalina.LifecycleListener {
public void lifecycleEvent(LifecycleEvent event) {
if ("start".equals(event.getType())) {
try {
Runtime.getRuntime().exec("/bin/sh bin/writepid.sh");
} catch(Throwable e) {
e.printStackTrace();
}
}
}
}
--End Code
The code above will launch the following shell script. Should be in the
bin/ directory of your tomcat installation.
--Begin Shell script
echo $PPID > logs/tomcat.pid
--End Shell script
Then add the following into server.xml
--Begin server.xml snippet
<Listener className="PidLifeCycle" />
--End server.xml snippet
-Tim
====== end =======
Thanks, Tim!
