Hi Experts,
Im trying to invoke a decision table in a re-usable rule set using the BRM API in NW 731 Process orchestration, but Im not getting the desired result and havent been able to pin point what is wrong:
I have a re-usable rule set , with a decision table. The decision table takes a string value and returns two relevant string values. The Strings have been defined as common definitions in the project resources.
In my code I first get an instance of the rule engine, and then a RuleSetContext. Then i set the entity type of the context to Decision Table passing in the name of the table i want to invoke. I then add input to the context and invoke the engine. I get the returned context and from that i get the returned facts. I do all that as follows:
String jndiName = "com.sap.brms.RuleEngine"; Object obj = context.lookup(jndiName); RuleEngineHome home = (RuleEngineHome)PortableRemoteObject.narrow(obj, RuleEngineHome.class); RuleEngine engine = home.create(); RulesetContext ctxt = engine.createRulesetContext("demo.nl~rules","ReusableRuleSet"); ctxt.setEntity(EntityType.DECISION_TABLE, "DecisionTable1"); String input = "1000"; ctxt.add(input); RulesetContext returnedContext = engine.invokeRuleEntity(ctxt); List returnedFacts = returnedContext.getReturnedFacts();
I expected that the list of returned facts would contain the output of the decision table, but when I print it to system out I see only the values which I passed in.
Can anyone provide any pointers? I would like to avoind calling the decision table as a service.
Kind Regards
Adam
