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 Banking 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 the Click deposit in the left pane of the Try-it tool and issue the following request to make a deposit:

    Code Block
    languagehtml/xml
    <amount>2432</amount>
<accountNumber>330021vc</accountNumber>

    You would get the following result:

    Code Block
    languagehtml/xml
    <message>Deposit was successfully done.5 percentage credits is given because the deposit amount is higher than 1000. Amount was : 2432. Your account balance is now : 2432</message>

  6. Issue Click withDraw in the left pane of the Try-it tool and issue another request as follows to make a withdrawal:

    Code Block
    languagehtml/xml
    <amount>200</amount>
<accountNumber>330021vc</accountNumber>


    You would get the following response:

    Code Block
    languagexml
     <message>Withdraw was successfully done. Amount was : 232200. Your new account balance is : 23192<2232</message>

  7. Alternatively, you can click Generate 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.
