Re: [Wrapper-user] pid file not working???

[Leif M. <le...@ta...>]

Dean,
The PID file should be getting written by the shell script that ships
with the Wrapper.  Could you please confirm that you are using our
script?  Most likely you are.

1) When you first start out, please confirm that no pid file, wrapper
process, or java process are running.
2) run the script with the "console" command.   This should launch the
Wrapper, and Java.
3) There should now be a PID file containing the Wrapper's PID.
Please confirm the id in the PID file, and also print out a "ps
-faux".
4) Does the PID in the file match that of the Wrapper?   If not,
please send me your shell script and wrapper.conf file as attachments.
Also please send me the name of your OS and version.  I should be able
to find the problem from that.

This is actually working correctly.  The Wrapper is actually launching
the WrapperStartStopApp class, not the Bootstrap class.  The
WrapperStartStopApp class is responsible for running the startup and
stop classes with their parameters at the appropriate times.  This
looks like you have set it up correctly:
org.tanukisoftware.wrapper.WrapperStartStopApp
org.apache.catalina.startup.Bootstrap 1 start
org.apache.catalina.startup.Bootstrap TRUE 1 stop

Cheers,
Leif
