<p>Hi Niyas - <br>
<br>
I'm also trying to implement similar approach wiht Spring and Drools, so I've done similar search and found some stuff. CHeck out this link:<br>
<br>
<a href="http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesWithSpringFramework">http://wiki.jboss.org/wiki/Wiki.jsp?page=RulesWithSpringFramework</a><br>
<br>
Using the sample code there I was able to come up with a component that encapsulates both the PackageBuilder and RuleBase - this component is called EventRulBase. Spring builds this component based on the configuration I specify in the aplicaitonContext-myapp.xml file... So the sequence goes something like this:<br>
<br>
1) Spring initializes the Beans defined in applicationContext-myapp.xml file at startup. The bean implements an init() method which I instruct Spring to invoke AFTER it finishes setting up all properties on the bean.... in the init() method I setup the components that read the DRL file, compile and initialize the RuleBase object. <br>
<br>
2) My EventRuleBase component is a Singleton that can return RuleBase objects from which calling clients can instantiate new Working Memory objects, assert objects and facts into it, fire rules, etc...<br>
<br>
I'm still in the process of building it but that's the general flow.<br>
<br>
Hope it helps - if you need more let me know.<br>
<br>
Regards,<br>
James<br>

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