pylucene in twistd app running as daemon

[Marcus <qw...@gmail.com>]

Hello:

in a previous post, a user expressed problems running pylucene in a twistd
app (running as a daemon)
I have similar issues.   I didn't see an answer in the postings.
Everything works fine when twistd runs in foreground mode (twistd
--nodaemon)

the trick would seem to be knowing where is the right place to run initVM.

anyone out there get this to work?

lucene 2.9.2
twisted 10.1

thanks,
Marcus

thanks, the problem though is digging deep enough into twisted to sort out
how to implement that,
and whether that means using twistd's tac files to initialize the app would
have to be abandoned for something more custom
for now, I subprocess a twistd foreground process, and exit the parent
process and it all seems to work well enough

initVM() _must_ be run from the main thread before calling anything 
involving the embedded JVM.

env.attachCurrentThread() _must_ be run from any other thread before calling 
anything involving the embedded JVM.
