RE: [Wrapper-user] Service question

[Ori A. <oa...@me...>]

Leif,
I have tried this with the wrapper. I used the java.exe pid and the dump
showed up in my log.
I have not tried the wrapper.exe pid. I imagine that it will send a
ctrl+break to that process and maybe you can install a handler for it if you
wish to do some of your own work before forwarding the dump.
Again, I haven't tried this and am not familiar with the code aside from
what the author outlined in his site. (Though it seems very interesting, I
might check it out soon :))

Happy to be able to give something back :)

Ori

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
