Hi folks,
This may well be rather premature, but I have been knocking up a little example
project to demo a web application built with Spring 4 and Drools 6. Notably,
*not* using the Drools Spring componentry because I prefer to roll my own
Spring components. It gives me a lot of freedom to make things work how I like.
I mention this, as there seem to be a lot of folks on this list with problems
relating to getting their Drools Spring XML config working, and I wanted to
show how easy it is to roll your own. There’s really not much code involved.
To try it out:
git clone [email protected]:gratiartis/qzr.git
cd qzr
mvn clean install
cd qzr-web
mvn tomcat7:run
And open: http://localhost:9090/
It seems to work fine on OSX and Windows 7. Hopefully it works for other
platforms too.
As I mention, this may be somewhat premature, because the application is very
much a work in progress (likely to be refactored lots!) and doesn’t do a lot
yet. It creates a KieSession attached to the HTTP session of each user, so that
users can have a chatty relationship with the rules engine. There is a web page
which uses JavaScript to call a REST API to get data such as “questions”, which
have been inferred in the rules engine. The idea being to have a conversation
whereby the rules engine asks a question and the user’s response will be
inserted as a knew ‘known’ fact. The rules are fired again to determine what is
now known and what additional questions should be asked.
I have plenty of vague ideas relating to future functionality, so I’ll be
beavering away at it. However, if anybody has thoughts on functionality which
would be worth demoing, then feel free to fire your thoughts in my direction
and I’ll see what I can do. If anybody looks closely enough to spot any bugs,
then feel free to mention them (I think you can raise issues on the GitHub
project), although there’s a pretty good chance that they’re just incomplete
functionality.
Hopefully it’s useful to someone. Enjoy!
Steve
