Re: [Wrapper-user] WrapperSimpleApp change to send SNMP traps...

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

Corey,
This is a feature that is currently under development.  Unfortunately, 
the way you
are doing it is not reliable.  It is the simple way to do it.  But will 
only allow reports
 to be sent for successful restarts of the JVM.

In order to make sure that mails are send for all failure modes, the 
events must be
mailed from the wrapper.exe process (developed in C).

If you want to do something in Java, you can tell after a restart has 
happened by
looking at the JVM Id from the WrapperManager on startup.  If it is 
greater than
1 then you know that a restart has just occurred.

Cheers,
Leif
