8. Test this process again, this time specifying different input criteria.

a. Click the Invoke icon to create a new test case.

b. Specify a partNo of part2 and a quantity of 5.

c. Click Continue.

The component should this time respond with a daysToDeliver value of 10

and a quantity of 50 (Figure A-81).

9. Optionally, you can test the other components the same way. Right-click them

in the Assembly Editor and select Test Component. Remember to remove

the emulators before testing them.

Creating the service implementation for Wholesaler B

Now we implement Wholesaler B. The business logic for this wholesaler is as a

Web service. Wholesaler B implements the same three business functionalities

as Wholesaler A, but it implements them in Java, not as a WS-BPEL process or

business rule:

򐂰 Place Order (implemented as Java class)

򐂰 Get Delivery Days (implemented as Java class)

򐂰 Cancel Order (implemented as Java class)

Appendix A. Building Wholesaler A and B service implementations 557

Wholesaler B also implements the same interfaces as Wholesaler A:

򐂰 Get delivery days

򐂰 Place an order

򐂰 Cancel an order

We can reuse the interfaces from Wholesaler A shown in Table A-5.

Table A-5 Wholesaler B interfaces

Table A-6, Table A-7, and Table A-8 show the business objects that are used in

the interfaces listed in Table A-5. The interfaces and business objects are

identical to Wholesaler A.
