Oracle Service Bus: How to create Proxy and Business Services Part 2.3: Tutorial; Create Business Services.

Create the Business Services In the routing a loan scenario, when the interest rate requested on a loan application is greater than or equal to 5%, then the loan application is routed to the normal loan processing service for approval. If the interest rate requested on a loan application is less than 5%, then the loan application must be approved by a manager, therefore it is routed to a manager approval service. Create the NormalLoan Business Service 1. In the Oracle Service Bus Console Change Center click Create to create a new session. 2. In the Project Explorer, select the BusinessService folder. 3. In the Select Resource Type list, select Business Service. 4. Enter a name for the service. In this case, enter NormalLoan. 5. For Service Type, select WSDL Web Service, then click Browse. Select the WSDL and port on which to base the business service: a. In the WSDL Browser, select the normalLoan WSDL b. Select the port (helloPort) for the WSDL. c. Click Submit. The text field for the WSDL port service type is populated with the value selected on the Create a Business Service - General Configuration page. 6. Click Next. 7. Accept the default protocol, http. 8. Select none for the Load Balancing Algorithm, since load balancing is relevant only when a service specifies multiple end points. When you specify multiple end points and a load balancing algorithm, if one end point is overloaded or not available at run time, the message can be sent to the next service in the list of end point URIs. In this case, there is only one service, therefore accepting the default behavior or selecting none does not affect the behavior of the proxy service at run time. 9. The End Point URI of the business service is the endpoint URI on the server on which the service is deployed. Ensure that the pre-populated value for the End point URI in the “Existing URIs” field is http://<host:port>/njws_basic_ejb/NormalSimpleBean. The host and port values specified for <host:port> represent the machine and port on which your Oracle Service Bus server is running. 10. Accept the default settings for the remaining options on the page and click Next. 11. In the Create a Business Service-HTTP Transport Configuration page, accept the default settings on this page, then click Next. 12. In the Create a Business Service-SOAP Binding Configuration page, accept the default settings and click Next. 13. In the Message Handling page, click Next. The Create a Business Service-Summary page is displayed. You can now check if all the settings of the business service have been implemented correctly. 14. Click Save to accept the configuration settings. To turn on monitoring for the NormalLoan business service, click the NormalLoan business service in the Resources pane. The View a Business Service page is displayed. The Operational Settings tab on this page has options to enable monitoring for the business service. To enable monitoring: a. Click the Operational Settings tab. b. Select the Enabled check box for the Monitoring field. c. Choose an aggregation interval for the service. The aggregation interval is the period over which aggregated statistics related to the service are computed for display in the Oracle Service Bus Console dashboard. You can also accept the default value for the Aggregation Interval, which is set to five minutes. d. Click Update. e. Activate the session. You have completed the configuration of the NormalLoan business service on Oracle Service Bus Console. Create the ManagerLoanReview Business Service To create the business service to which a loan application is routed when the interest rate requested in that loan application is less than 5%. Follow the same tasks as described in the previous section on creating the ManagerLoanReview business service, but use the configuration parameters in the following table. Summary You have created two business services (NormalLoan and ManagerLoanReview), a proxy service (LoanGateway1) and two WSDL resources (normalLoan and ManagerApprovalService) that are the resources required for this tutorial.
