Rule

service configuration (service.rsl)

An in-line rule set is used within the service.rsl file as follows.

Deploying and

testing the

service

1. Deploy the rule service through the BRS management console. You can follow either of the two methods:
   
   
   • Bundle all artifacts in an .aar file and upload it (Rule Service -> Upload menu).
   • Create using the Rule Service wizard UI (Rule Service -> Create menu).
   
   The above steps are discussed in detail in section  Exposing Rules as Services.
    
2. After deployment, click on List under Services in the main tab of the management console. The service will appear in the Deployed Services page.
3. Click HealthCare Service to access the dashboard of the service.
4. Click Try this service in the Client Operations widget of the dashboard to invoke the Try-it tool.

5. Issue a request similar to the following in the Try the HealthCareServiceservice window-it tool.
   

   Code Block
   language html/xml
   <medication>Cefuroxime</medication> <age>54</age> <creatinineLevel>1.2</creatinineLevel>

   Image Removed
   The response would be as follows:
   

   Code Block
   language html/xml
   <message>250 mg every 24 hours for 14 days</message>

   
   

6. Image Removed
    Send another request as follows:

   Code Block
   language html/xml
   <medication>Amoxicillin</medication> <age>20</age>

   
   Image Removed
   You would get the following response:

   Code Block
   language html/xml
   <message>500 mg every 24 hours for 14 days</message>

   Image Removed

7. Alternatively, you can click Generate Axis2 Client in the Client Operations widget of the dashboard to invoke the service. A client using generated stub codes is shown below where the codes were generated with the Unpacks the databinding  classes check box checked.
   
   

   Code Block
   language java
   package org.wso2.carbon.samples; import org.apache.axis2.AxisFault; import org.wso2.carbon.samples.healthCareService.patientDetail.Dose; import org.wso2.carbon.samples.healthCareService.patientDetail.Patient; import org.wso2.carbon.samples.healthCareService.patientDetail.PatientDetail; import org.wso2.carbon.samples.healthCareService.stub.HealthCareServiceStub; import java.rmi.RemoteException; public class HealthCareServiceTestCase { public static void main(String[] args) { try { HealthCareServiceStub healthCareServiceStub = new HealthCareServiceStub("http://localhost:9763/services/HealthCareService"); PatientDetail patientDetail = new PatientDetail(); Patient patient = new Patient(); patient.setAge(43); patient.setCreatinineLevel(1.0); patient.setMedication("Levofloxacin"); Patient[] patients = new Patient[1]; patients[0] = patient; patientDetail.setPatientDetail(patients); Dose[] doses = healthCareServiceStub.recommendDose(patients); String result = doses[0].getMessage(); System.out.println(result); } catch (AxisFault axisFault) { axisFault.printStackTrace(); } catch (RemoteException e) { e.printStackTrace(); } }
