1. Create a valid jar containing the java classes of facts and results defined for the "Order Approval" sample usecase use case in section Sample Rule Definition.
2. Create a rule service configuration using the instruction in section BRS Configuration Languageinstructions in File-Based Configuration. The configuration file used for the sample is shown below, which is named as service.rsl (Rule Service Language).
| Code Block | ||||
|---|---|---|---|---|

<ruleService
name="OrderApprovalService"
xmlns="http://wso2.org/carbon/rules"
targetNamespace="http://com.test/orderApproval">
<ruleSet>
<rule resourceType="regular" sourceType="file">orderApprovalRules.drl</rule>
</ruleSet>
<operation name="placeOrder">
<input wrapperElementName="placeOrder" namespace="http://com.test/placeorder">
<fact elementName="order" namespace="http://com.test/placeorder" type="samples.userguide.PlaceOrder"></fact>
</input>
<output wrapperElementName="placeOrderRespone" namespace="http://com.test/placeorder">
<fact elementName="orderAccept" namespace="http://com.test/placeorder" type="samples.userguide.OrderAccept"></fact>
<fact elementName="orderReject" namespace="http://com.test/placeorder" type="samples.userguide.OrderReject"></fact>

8. The Try-It tool can be used to test the sample through a request similar to the one shown bellow.
| Code Block |
|---|
<symbol>Company A</symbol> <quantity>223</quantity> <price>14</price> |
9. Each rule can be tested by changing values in the symbol, price and quantity. For the request given above, the response will be as follows.
| Code Block | ||
|---|---|---|
| ||
<brs:placeOrderResponse>
<brs:result>
<brs:OrderAccept xsi:type="ax2277:OrderAccept">
<ax2275:message>Accepted order for: 223 stocks of Company A at$ 14.0</ax2275:message>
</brs:OrderAccept>
</brs:result>
</brs:placeOrderResponse> |
10. Also, the WSDL of the service can be used to generate client-side code (stub) required for the service invocation. There is an option for code generation in the services management page. A client using generated stub codes is shown below and the codes are generated with option - "Unpacks the databinding classes".
