Hi,
2 questions:
1) why do call yourself Sisyphus? Is it really all for meaningless, endless
:)
2) I'd like to call some perl from a running Java process. I'm using a
vendor api and framework to build custom code. The way it works is I have
to write some java (see below), then compile within Eclipse using a supplied
Ant xml, which turns my code into a Jar that is deployed onto the server.
The vendor's Java app reads a DB that indicates where the Jar is located
and the class and method to call under various situations.
I've written a Inline::Java callback in the past, but it was initiated via
Perl. That is, I launched a perl process, that then instantiated some Java
that in turn called back into the perl.
In reading the callback docs I can't seem to grok how to make it all happen
from Java and my Jar correctly.
Below is the code.
Any guidance would be hugely appreciated.
Thanks
Jay
