Oracle® SOA Suite 11.1.1.2

Hands-On Workshop OSB Lab 2b


This is an optional lab which Needs to be completed before doing Lab3 in

which you can substitute an Oracle Service Bus call out to the CreditScore web service

reference created near the end of Lab2

Desktop icon or right click on it and selecting Open.

2. Select the Start radio button and click OK.

session.


5. We will now create a Proxy Service (incoming) and Business Service (outgoing)

to take input from the BPEL PermitProcess flow and call the CreditScore web service

we deployed in Lab 2. The Proxy Service will use the same WSDL definition as our

web service so payloads will easily map. Even though this is a simplistic example, it

enforces the notion that all messaging in our design will be brokered by the service

bus.
