Drools 6.0 on Google App Engine 1.9.0
user3636575 via StackOverflow
Is there anyway to get Drools 6.0 to run with Google AppEngine? I know there's a solution with Red Piranha, https://code.google.com/p/red-piranha/wiki/ModifyDroolsRunInGoogleAppEngine, out there that works with 5.5.0, but I kinda do want to use the new PHREAK algorithm that 6.0 uses and I'm not sure that the solution from red piranha will work with 6.0. Anyways here's my stack trace when I try to run the following code in App Engine devserver.
Thanks, Eric
public class SampleBusinessObject extends BaseBusinessObject
{
public void testDrools()
{
KieServices kieServices = KieServices.Factory.get();
KieContainer kContainer = kieServices.getKieClasspathContainer();
KieSession kSession = kContainer.newKieSession();
Account account = new Account(200);
FactHandle accountFact = kSession.insert(account);
kSession.fireAllRules();
account.withdraw(250);
kSession.update(accountFact, account);
kSession.fireAllRules();
}
}
