Re: [Wrapper-user] Service question

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

Ori,
Thanks for pointing that out, I'll take a look at it and see if it is
something that can
be used with the Wrapper. I was able to see the site no problem. Reading
over
the description, it looks like the definition of a "hack". (Not a bad
word by the way).
But sometimes, that is exactly what is needed. At the least, it sounds
like I could
learn a few things from the source.

Have you tried this with the Wrapper? I would imagine that it would work
if you
tried using either the Wrapper or JVM pids.

Cheers,
Leif
