I have tried of using the sample coding given the link given by you:
But i am getting the following error:

Check out 'Spring Modules' subproject - it has a DROOLS
integration module.
Haven't used it myself yet, so not sure whether it's mature/compatible with
most recent release.

Subject: [rules-users] Drools With Spring Framework Problem
Hi all,
I am in need of integrating Drools JBoss Rule Engine with Spring Framework.
I have tried sample rule engine examples in the Drools in the
standalone with the help od drools IDE for eclipse 3.2.
And I also tried some example in the Spring Framework,to know how it
works. I have tried some examples in IOC, MVC and JDBC in the spring
framework.
Now, I want to use both Drools and Spring Framework in such a way that
Spring will have the MVC application and it should validate the rules,
which written in the drools (.drl)
I don't know how to begin with/what are he configuration files needed
to setup. PLease if anyone have the sample coding on Drools with
Spring or any other links willl be very useful.
And also, guide me what are the things need to be know for Spring with
Drools. While I have searched in google, lots of things came up like:
Use JSR94... (which is mentioning to configure RuleServiceProvider,
RuleRuntime, RuleSet..and others..which seeme to be confusing and not
clear)
Whether there are any API for drools with spring that DROOLS is
supporting..like org.drools.spring.metadata.ArgumentMetadataSource. I
don't find these Drools API section
