Re: [Wrapper-user] Wrapper service starts then stops but java keeps running correctly

Steven,
Unfortunately no, this is not going to work as is.  The Wrapper only
monitors the JVM that it launches itself.  One option would be to
figure out the command line that your first JVM is generating to
launch the second JVM.  Then have the Wrapper launch it directly.

The only other way to do this is to have your primary JVM
wait until its child JVMS have completed.  The problem is that
when you start adding various failure modes, things are going to
get complicated for you very quickly.

It is pretty difficult for the Wrapper to try to monitor the child
processes of the JVM it launches.  There would need to be a way
for it to figure out which ones should be waited for and which
ones could be left running etc.   What happens if it crashes rather
than completing, etc, etc, etc.

Cheers,
Leif
