by SHIMI Abdelouahad ( Prestataire )
I was deploy Guvnor(drools-5.0.0.CR1-guvnor) as an exploded archive on
the JBoss Application Server(version jboss-4.2.3.GA).
And I was
* Create categories, ok
* Create package,ok
* Importe model, ok
* Create rule, ok
And create a simple Drools application(with Eclipse version 3.4 and
pluging drools 5.0) that will use a package served by Guvnor:
public class GuvnorTest {
public static final void main(String[] args) {
RuleAgent agent =
RuleAgent.newRuleAgent("/Guvnor.…
[View More]properties");
RuleBase ruleBase = agent.getRuleBase();
WorkingMemory workingMemory =
ruleBase.newStatefulSession();
Driver d = new Driver("Jarek", 20, null);
workingMemory.insert(d);
workingMemory.fireAllRules();
for (Iterator i = workingMemory.iterateObjects();
i.hasNext();) {
System.out.println(i.next().getClass().getCanonicalName());
}
}
}
The properties file:
url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package
/myNewPackage/LATEST
And When the application is run I have this Exception:
RuleAgent(default) EXCEPTION (Thu Jun 18 10:46:40 CEST 2009): null.
Stack trace should follow.
