Deploying and Testing the Rule Service
A 1. Deploy the rule service can be created either by creating 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, the service will appear in the "Deployed Services" window of the BRS management console. Access the service's dashboard by clicking on it.
3. In the "Client Operations" widget of the dashboard, invoke the Try-it tool
...
to test the service.
4. In the service's TryIt window, issue a request similar to the following.
