How to update facts in Script task (RuleFlow)
by joeyoungkc
Hi,
I'm trying to update the facts before a flowgroup and after a script
task(written in java). I was thinking of calling update(myFact) inside the
script task, but how do I call it?
Do I need to press in the session to the parameter map and call
session.update(FactHandle handle, Object object)??
--------------------------------------------------
StatefulKnowledgeSession session = getKnowledgeAgent("abc")
.getKnowledgeBase().newStatefulKnowledgeSession();
Map<String, Object> parameterMap = new HashMap<String,
Object>();
parameterMap.put("myFact",myFact);
session.insert(myFact);
session.startProcess("rruleflow", parameterMap);
session.fireAllRules();
--------------------------------------------------
I'm new to drool, please help!

How to rethrow Exceptions from Drools 5 functions
by Matthew Erler
I would like to write a utility function that works with java.text.SimpleDateFormat and several more date-related Java classes. The classes can throw Exceptions that the function caller should know about. Is it possible for a function to be declared such that it can throw any Exception back to the caller?

RuleAgent - loading rules help ?
by Ivan Peshev ( M-Tel )
Hello,
Is there a way to tell RuleAgent to load rules not only from remote URL ?
i.e. some rules from URL and some rules from LOCAL path on my computer.
(e.g.: c:\some\folder\rule.drl)
Or if it's not possible exactly that way is there another way to have some rules loaded from URLs and some rules loaded from local path ?
Best Regards
Ivan
