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

New subject: Drools With Spring Framework Problem
Hi Niyas,
This is something I faced yesterday but did not had the time to work
on it yet. Basically, 2 problems:
1. Error message is crap... we need to improve that.
2. It should not be raising any error. The error means you have a String
attribute you are trying to compare using operators like >, <, >=, <=.
Example:
Person( name > 'Edson' )
And I think the above should work but is not working. I will open a
JIRA for that.
Meanwhile, if you need to have such constraint, a workaround is to
use a predicate:
Person( $n : name, ( $n.compareTo( 'Edson' ) > 0 ) )

New subject: Drools With Spring Framework Problem
Hi,
WIKI Knowledgebase have a solution for the error
like:org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem;
I have added the JANINO compiler in the PackageBuilderConfiguration in
the Java Code: But It's not resolving my problem and the same error
message is coming:
My Code:
public class RuleBaseBeanFactory implements FactoryBean, InitializingBean {
private List<Resource> drlResourceList;
private RuleBase ruleBase;
private PackageBuilderConfiguration packageBuilderConfiguration;
public void setDrlResourceList(List<Resource> drlResourceList) {
this.drlResourceList = drlResourceList;
}
public void afterPropertiesSet() throws Exception {
Assert.notEmpty(drlResourceList, "drlResourceList must not be empty");
PackageBuilder builder = (packageBuilderConfiguration != null
? new PackageBuilder(packageBuilderConfiguration) : new
PackageBuilder());
packageBuilderConfiguration.setCompiler(packageBuilderConfiguration.JANINO);
for (Resource resource : drlResourceList) {
builder.addPackageFromDrl(new
InputStreamReader(resource.getInputStream())); // TODO will use
default encoding which might not be wanted
}
ruleBase = RuleBaseFactory.newRuleBase();
ruleBase.addPackage(builder.getPackage());
}
public RuleBase getObject() {
return ruleBase;
}
public Class getObjectType() {
return RuleBase.class;
}
public boolean isSingleton() {
return true;
}
public void
setPackageBuilderConfiguration(PackageBuilderConfiguration
packageBuilderConfiguration) {
this.packageBuilderConfiguration = packageBuilderConfiguration;
}
}
Please suggest a solution..
