[rules-users] A question about use sliding window with and without entry point

[Yu Changyuan]

Thank you for your response.

I write my code in scala(that's why I don't include code in first post),
and use sbt as build tool. I upload the code to github, at
 https://github.com/yuchangyuan/drools-test1s , so just clone the repo to
get the code.

sbt 0.13 should be installed(see http://www.scala-sbt.org/ for howto
install) before the code can be built and run,
after install sbt, just type 'sbt run' in project root directory(the
directory contain 'build.sbt' file) to compile and run the code.

For drools 5.6.0-SNAPSHOT, I will try later.
