[rules-users] Facing Problem in BRL
Hi,
I am using Drools-Expert. I am having a class "Person" with data members as
age and discount.
I am trying to create a .brl. I have these statements in drools.package
package com.rules;
import com.model.PersonDetails;
and in the example.brl I am providing the details of when and then
conditions
but on execution I am getting the following error :
java.lang.RuntimeException: [4] Unable to expand: PersonDetails( age <
"20" )[6] Unable to expand: PersonDetails fact0 = new PersonDetails
();[7] Unable to expand: fact0.setDiscount( 10 );[8] Unable to
expand: insert(fact0 );
It would be helpful is somebody guide me on how execute it.
Also, I am creating the knowledgebase as:
private static KnowledgeBase createKnowledgeBase() {
KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder();
builder.add (ResourceFactory.newClassPathResource(
"com/rules/example.brl"),ResourceType.BRL);
if (builder.hasErrors()) {
throw new RuntimeException (builder.getErrors().toString ());
}
KnowledgeBase knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase();
knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages ());
return knowledgeBase;}
