c. Use the process outlined in “Generate the Web service clients” on

page 348 to regenerate the client to use the bus.

7. To test the service, follow these steps:

a. Enable the Web Services Explorer tool, by selecting Windows →

Preferences → Workbench → Capabilities. Enable all the features

listed under Web Services Developer.

b. Create a simple project and a simple folder under it. Unzip the WSDL zip

file, and import it into the folder. Right-click the service WSDL and select

Web Services → Test with Web Services Explorer.

8. Install and configure the router mediation application, for the incoming

request for HomeDelivery using the process outlined in 10.7.8, “Configure the

router mediation” on page 350. In this step you will:

a. Install the RoutingMediationsEJBEAR application

b. Define the DeliveryRequestMediation mediation on the bus

c. Mediate the port for the HomeDelivery destination.

9. Install and configure the aggregator mediation application, for the incoming

responses to the for HomeDelivery and BusinessDelivery services using the

process outlined in 10.7.9, “Configure the aggregator mediation” on

page 351. In this step you will:

a. Create two queue destinations on the bus, DeliveryResponseDestination

and TempDestination

b. Install the AggregatorEJBEAR mediation application.

c. Define the DeliveryResponseMediation mediation on the bus.

d. Mediate the DeliveryResponseDestination queue.

10.Save the configuration.

Processor application

If you are going to run with the MailService or JCAModule applications, you will

need to modify Processor.Java to uncomment the lines that activate these calls.

You will find Processor.java in the ProcessorEJB module at

com.ibm.patterns.serialProcess.Processor.java class.

Appendix A. Sample application install summary 481

The lines of code to be uncommented are found in the following three methods in

Example A-6:

Example: A-6 Uncommenting MailService and JCAModule

private void createCustomer() {

//Call to CreditRating application

String creditRating = new

ProcessorWebService().getCreditRating(customerDetails);

if (isCreditSatisfactory(creditRating)) {

//Credit is Satisfactory

//Create customer in CRM and send Acceptance Mail

//Uncomment if you have the JCA service configured

//ProcessorJCA.storeCustomerDetails_CICS(customerDetails);

//Uncomment if you have the Mail service configured

//new MailService().sendActivationMail(customerDetails);

System.out.println("Customer created successfully....");

}

else {

//Credit rating is not satisfactory

//Delete customer from Db2 and send rejection E-mail

deleteCustomerfromDB();

//Uncomment if you have the Mail service configured

//new MailService().sendRejectionEmail(customerDetails);

System.out.println("The customer does not have satisfactory credit

and will not be created...");

}

}

private void deleteCustomer() {

//Uncomment if you have the JCA service configured

//ProcessorJCA.deleteCustomerDetails_CICS(pkey);

deleteCustomerfromDB();

//Uncomment if you have the Mail service configured

//new MailService().sendDeletionEmail(pkey);

System.out.println("Customer deleted successfully...");

}

private void updateCustomer() {

//Uncomment if you have the JCA service configured

//ProcessorJCA.updateCustomerDetails_CICS(pkey);

//Uncomment if you have the Mail service configured

//new MailService().sendUpdationEmail(customerDetails);

System.out.println("Customer details updated successfully...");
