[rules-users] Drools Guvnor API information?

Mon Feb 14 03:03:29 EST 2011

Hey Luciano, Meanwhile i tries pumping in the rule with a webdav api
(Sardine in my case) and that seems to work and trigger ok for me. this is
how i did that

public class SardineTest {

public static void main(String[] args) throws SardineException {
Sardine sardine = SardineFactory.begin("admin", "admin");
List<DavResource> resources = sardine
.getResources("
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/webdav/packages
");
for (DavResource res : resources) {
System.out.println(res); // calls the .toString() method.
}

addARule();
}

private static void addARule() throws SardineException {
Sardine sardine = SardineFactory.begin("username", "password");
String ruleDescription = "when Entity(entityName==\"Car1s\") then
System.out.println( \"*************rule executed\")";
byte[] data = ruleDescription.getBytes();
sardine.put("
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/webdav/packages/Analytics/SimpleDRLRule.drl",
data);
System.out.println("Rule added ...");
}

}

once i did this, I could see the rule added as a technical rule on the
guvnor web app ... the and then triggered to rule with something like this

public class GuvnorTest {
 @Test
public void testDroolsWithGuvnor() throws Exception {
KnowledgeBase knowledgeBase = createKnowledgeBase();
StatefulKnowledgeSession session =
knowledgeBase.newStatefulKnowledgeSession();
try {
Entity entity = new Entity();
entity.setEntityName("Car1s");
session.insert(entity);
Assert.assertTrue(session.getFactCount() == 1);
System.out.println("And the count is  " + session.getFactCount());
 session.fireAllRules();
System.out.println("And the count is  " + session.getFactCount());
Assert.assertEquals(1, session.getFactCount());
}
finally {
session.dispose();
}
}

private static KnowledgeBase createKnowledgeBase() {
 KnowledgeAgentConfiguration kaconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
 kaconf.setProperty( "drools.agent.scanDirectories", "false" );
 KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent( "test
agent", kaconf );
 kagent.applyChangeSet(
ResourceFactory.newClassPathResource("opal-guvnor.xml"));
 return kagent.getKnowledgeBase();
}
}

where opal-guvnor.xml is my change set file and goes like this

<change-set xmlns='http://drools.org/drools-5.0/change-set'
    xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
    xs:schemaLocation='http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd'
>
    <add>
         <resource source='
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/Analytics/LATEST.drl'
type='DRL' basicAuthentication="enabled" username="admin" password="admin"/>
    </add>
</change-set>

not sure if this is the right / best way but at least could add a rule to
the repository with this. Ideally,

1) I would like to run a validate / verify to see that the rule has been
added correctly, I dont know the api to do that
2) I would like to rebuild my package and/or create a new snapshot, dont
know how to do that either though the rule seems to execute without doing
that.
3) Have not given any thoughts about security etc right now ...

@Drools experts, your thoughts?
