Chapter 23. Pricing Rule Example

Procedure 23.1. Task

1. Open your console.
2. Open the file PricingRuleDTExample.java and execute it as a Java application. It will produce the following output in the console window:

   Cheapest possible
   BASE PRICE IS: 120
   DISCOUNT IS: 20

3. Use the following code to execute the example:

   DecisionTableConfiguration dtableconfiguration =
       KnowledgeBuilderFactory.newDecisionTableConfiguration();
           dtableconfiguration.setInputType( DecisionTableInputType.XLS );
   
           KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
   
           Resource xlsRes = ResourceFactory.newClassPathResource( "ExamplePolicyPricing.xls",
                                                                   getClass() );
           kbuilder.add( xlsRes,
                         ResourceType.DTABLE,
                         dtableconfiguration );
   

   The DecisionTableConfiguration object's type is set to DecisionTableInputType.XLS.
   There are two fact types used in this example, Driver and Policy. Both are used with their default values. The Driver is 30 years old, has had no prior claims and currently has a risk profile of LOW. The Policy being applied for is COMPREHENSIVE, and it has not yet been approved.
