Drools 6.0 (JudCon 2013)

Not Quite There Yet
•The SkyNet funding bill is passed.
•The system goes online on August 4th, 1997.
•Human decisions are removed from strategic
defense.
•SkyNet begins to learn at a geometric rate.
•It becomes self-aware at 2:14am Eastern time,
August 29th
•In a panic, they try to pull the plug.
•And, Skynet fights back
Saturday, 29 June 13

Changes
• Conventions:
• droolsjbpm -> kie
• knowlege -> kie
• Examples
• KnowledgeBase -> Kie
• StatefulKnowledgeSession -> KieSession
• StatelessKnowledgeSession - StatelesKieSession
• Legacy API Adapter JAR
• Most API’s should work with legacy adapter
• KnowledegAgents have not been ported, PKG’s are not
longer the unit of deployment

KieModules
• Discovery
• META-INF/kmodule.xml
• Convention based
• No programmatic api for building
• Multiple Named entities
• Inheritence of Resources
• Defaults for lazy people
• Version built in a standard

Git Hub Examples• https://github.com/droolsjbpm/drools/tree/master/drools-
examples-api

KieModules
<kmodule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://jboss.org/kie/6.0.0/kmodule">
</kmodule>
KieServices ks = KieServices.Factory.get();
KieContainer kContainer = ks.getKieClasspathContainer();
KieSession kSession = kContainer.newKieSession();
kSession.setGlobal("out", out);
kSession.insert(new Message("Dave", "Hello, HAL. Do you read me, HAL?"));
kSession.fireAllRules();

KieModules• Named Entities and JAR on Classpath
• Creates one KieBase
• Includes resources from package matching
kbase name
<kmodule xmlns="http://jboss.org/kie/6.0.0/kmodule">
<kbase name="kbase1">
<ksession name="ksession1"/>
</kbase>
</kmodule>
KieSession kSession = kContainer.newKieSession("ksession1");

KieModules• Named Entities, with inheritence and JAR on
Classpath
• Two projects, one “includes” from the other
<dependency>
<groupId>org.drools</groupId>
<artifactId>named-kiesession</artifactId>
<version>6.0.0-SNAPSHOT</version>
</dependency>
<kbase name="kbase2" includes="kbase1">
<ksession name="ksession2"/>
</kbase>
kSession.insert(new Message("Dave", "Open the pod bay doors, HAL."));

KieModules• Package location can over-ride kbase name defaults
<kbase name="WumpusMainKB" packages="org.drools.games.wumpus.server,
org.drools.games.wumpus.server.view">
<ksession name="WumpusMainKS" />
</kbase>
<kbase name="WumpusClientKB" packages="org.drools.games.wumpus.client">
<ksession name="WumpusClientKS"/>
</kbase>
KieContainer kc = KieServices.Factory.get().getKieClasspathContainer();
final KieSession serverKsession = kc.newKieSession( "WumpusMainKS");
final KieSession clientKsession = kc.newKieSession("WumpusClientKS");

Dynamic KieModules
• JARs can be loaded from URLs into KieRepository
• Once loaded they can be resolved via ReleaseId
KieRepository kr = ks.getRepository();
KieModule kModule = kr.addKieModule(ks.getResources().newFileSystemResource(
getFile("default-kiesession")));
KieContainer kContainer = ks.newKieContainer(kModule.getReleaseId());
Object msg1 = createMessage(kContainer,
"Dave", "Hello, HAL. Do you read me, HAL?");
kSession.insert(msg1);

Dynamic KieModules
• kie-ci use embedded maven for remote
discovery
<dependency>
<groupId>org.kie</groupId>
<artifactId>kie-ci</artifactId>
</dependency>
// Install example1 in the local maven repo before to do this
KieContainer kContainer = ks.newKieContainer(
ks.newReleaseId("org.drools",
"named-kiesession",
"6.0.0-SNAPSHOT"));
Object msg1 = createMessage(kContainer,
"Dave", "Hello, HAL. Do you read me, HAL?");
kSession.insert(msg1);

Dynamic Modules
// create a new kjar
InternalKieModule kJar2 = createKieJar(ks, releaseId, "rule2", "rule3");
// deploy it on maven
repository.deployArtifact(releaseId, kJar2, kPom);
// since I am not calling start() on the scanner it means it won't have
automatic scheduled scanning
KieScanner scanner = ks.newKieScanner(kieContainer);
// scan the maven repo to get the new kjar version and deploy it on the
kcontainer
scanner.scanNow();
// create a ksesion and check it works as expected
KieSession ksession2 = kieContainer.newKieSession("KSession1");
checkKSession(ksession2, "rule2", "rule3");

kmodule.xml Editor

Programmatic API
• Builder API, for tooling integration
• Incremental compilation, and problem
reporting
KieRepository kr = ks.getRepository();
KieFileSystem kfs = ks.newKieFileSystem();
kfs.write("src/main/resources/org/kie/example5/HAL5.drl", getRule());
KieBuilder kb = ks.newKieBuilder(kfs);
kb.buildAll(); // kieModule is automatically deployed to KieRepository if
successfully built.
if (kb.getResults().hasMessages(Level.ERROR)) {
throw new RuntimeException("Build Errors:n" + kb.getResults().toString());
}
KieContainer kContainer = ks.newKieContainer(kr.getDefaultReleaseId());

• Contradiction handling with JTMS
• Clean separation of exception logic
• TMS now has pluggable Belief System
• Simple TMS support

•A rule “logically” inserts an object
•When the rule is no longer true, the object is retracted.
