Re: [Wrapper-user] Restart VM

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

Jacques,
    You should be able to download the new jars and place them in the 
correct directory.
That should be doable without the Wrapper.  (You may have problems with 
the IBM JVM?
because it locks the files?  This is from memory, so it may be wrong :-/)

    Anyway, once you have the new jar files in place, all you need to do 
is trigger the
Wrapper to restart the JVM.   You could do that using a filter as you 
specified or
you could simply call WrapperManager.restart().  I would suggest the 
later as it does
not require anything in the wrapper.conf file.

Cheers,
Leif
