An application developer has created several decision service projects for a Retail Pricing set of rules. The developer is asked to create the client application to execute the business rules in a stateless manner with transaction control at the rule session level. The client application will be deployed on the same application server as the Rule Execution Server components.
How should the application developer invoke the business rules from within this client application? 

1. From within Rule Designer, create a new Client Project for RuleApps.
2. In the project creation wizard:
- choose the Retail Pricing RuleApp project.
- choose the appropriate ruleset.
- specify default input parameters for the ruleset.
- specify a Rule Execution Server configuration.
3. Add Java code in the generated ExecutionHook.preprocessing() method to pass business data
to the ruleset.
4. Deploy the Client Project for RuleApps to the Rule Execution Server. 

2. Navigate to the “Retail” ruleset in the “Pricing” RuleApp.
3. Use the REST service to generate an XML or a JSON payload.
4. Optionally test the generation of the payload and its execution from the Rule Execution Server
console.
5. From the client application, send the request as the payload of an HTTP call through a POST
method to the corresponding URI. 

Include the following code in the client application:
IlrSessionFactory factory = new IlrSessionFactory();
IlrStatelessSession session = factory.createStatelessSession(TRANSACTION);
IlrSessionRequest sessionRequest = factory.createRequest
(“/Retail/Pricing”);
sessionRequest.addInputParameter(0, “shoppingCart”, cart);
IlrSessionResponse sessionResponse = session.execute(sessionRequest); 

Include the following code in the client application:
IlrSessionFactory factory = new IlrEJBSessionFactory();
IlrStatelessSession session = factory.createStatelessSession;
IlrSessionRequest sessionRequest = factory.createRequest();
sessionRequest.setRulesetPath(“/Retail/Pricing”);
Map inputParameters = new Hashmap ();
InputParameters.put(“shoppingCart”, cart);
sessionRequest.setInputParameters(inputParameters);
IlrSessionResponse sessionResponse = session.execute(sessionRequest)
