Ich arbeite an Drools und meinem folgenden Code
import org.drools.RuleBase;
import org.drools.agent.RuleAgent;
import org.drools.definition.type.FactType;
public class MortgageApplicationTest {
/**
* @param args
* @throws IllegalAccessException
* @throws InstantiationException
*/
public static void main(String[] args) throws InstantiationException, IllegalAccessException {
RuleAgent agent = RuleAgent.newRuleAgent("/mortgageapproval.properties");
RuleBase rb = agent.getRuleBase();
FactType appType = rb.getFactType("mortgages.LoanApplication");
FactType incomeType = rb.getFactType("mortgages.IncomeSource");
Object application = appType.newInstance();
Object income = incomeType.newInstance();
appType.set(application, "amount", 25000);
appType.set(application, "deposit", 1500);
appType.set(application, "lengthYears", 20);
incomeType.set(income, "type", "Job");
incomeType.set(income, "amount", 65000);
rb.newStatelessSession().execute(new Object[] {application, income});
System.out.println(application);
}
}
Nachfolgend ist meine Datei mortgageapproval.properties aufgeführt
url=http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/mortgages/LATEST
userName=admin
password=admin
Diese ganze Code-Setup ist folgende 401 Fehler auslöst

Exception in thread "main" java.lang.NullPointerException
.... Ich habe die Authentifizierung nur in der Datei component.xml des Tomcat angegeben, die wie folgt lautet
<role rolename="manager-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>
<role rolename="admin"/>
<user username="admin" password="admin" roles="admin"/>
In meiner drools' component.xml zeigt folgende Zeile, dass ich keine Authentifizierung angegeben habe
<!-- NO authentication. This will bypass the login screen when you hit the app. Everyone is "guest" -->
<security:identity authenticate-method="#{nilAuthenticator.authenticate}"/>
Bitte helfen Sie mir aus, da es nicht viele drools Entwickler gibt... Ich erhalte keine erforderliche Hilfe....
vielen Dank im Voraus
