[Wrapper-user] Performing actions on (re)start, shutdown of JVM

[Martin G. <ma...@mi...>]

Hallo,
when using Wrapper 3.1.2 with my Java application, my Java application 
requires to perform some specific actions during start/RESTART of JVM 
and shutdown of JVM.
These actions include, but are not limited to:
- deleting device lock files on certain platforms (e.g. serial line 
locks on Linux)
- shutdown of heartbeat service

The shutdown actions must be performed no matter what type of shutdown 
occured ( WrapperManager.restart(), stop, stopImmediate() calls;
System.exit() call; crash of JVM (both in Java and Native code), killing 
JVM process from command line).

Is it possible to configure wrapper to perform these actions (e.g. in 
the form of calling some scripts) ?

The naive try = launching my script "runjava" (which performs the start 
actions, runs JVM and then performs shutdown actions) from 
wrapper.java.command does not work properly - wrapper was watching the 
/bin/sh instead of java process, sometimes java processes kept 
accumulating when I was playing (since wrapper took care for shell 
processes, not for the increasing number of JVM).

Thanks in advance.


Martin
