[rules-users] Stateful Session giving major issues
Hello,
I am using Drools 5.2. I am not sure why not able to find the result here.
I am supposed to get the value from the Action in this rule as shown below.
But its never found. Kindly assist me with what is it that i have'nt
included.
First the rules
//generated from Decision Table
import boa.poc.java.SSI;
import boa.poc.java.CMPG_REF;
import boa.poc.java.Result_Rules;
// rule values at C12, header at C7
rule "Access sql table_12"
when
ssi : SSI(CD == "ES", EOC_IN == "Y", IN == "N")
cmpgRef : CMPG_REF(CMPG == 123, 01_NO == "12")
result : Result_Rules(dummyCond == "result")
then
result.setDummyAction("Access I");
end
Second the code
@SuppressWarnings("rawtypes")
public HashMap<String, List> retrievRuleResult(HashMap hm) {
try {
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
SSI ssi = (SSI)hm.get("pa_cycle_ssi");
CMPG_REF cmpRef = (CMPG_REF)hm.get("pa_cmpg_ref");
Result_Rules rulesResult = (Result_Rules)hm.get("dummyCond");
StatefulKnowledgeSession ksession =
kbase.newStatefulKnowledgeSession();
ksession.insert(ssi);
ksession.insert(cmpRef);
ksession.insert(rulesResult);
ksession.fireAllRules();
ksession.dispose();
System.out.println("Result 1 : "+rulesResult.getDummyAction());
return ;
}
public KnowledgeBase readKnowledgeBase() throws Exception {
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource("poc/rules/rules.pkg"),
ResourceType.PKG);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() > 0) {
for (KnowledgeBuilderError error: errors) {
System.err.println(error);
}
throw new IllegalArgumentException("Could not parse knowledge.");
}
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
return kbase;
}
