2. You’ll see five options: UDDI, WSDL URL, WSIL URL, File, Legacy WSDL (Prior to 8.48).
3. We are going to use WSDL URL assuming that you have the URL of the Web service that you are trying to use.
4. Check WSDL URL radio button and enter Web Service URL. Click ‘Next’ button.
5. This next screen will show you the name of WSDL service. Select the serviceby checking the box. If you would like to see the service WSDL, click View WSDL hyperlink.
6. Hit the ‘Next’ button which will take you to step 3. In this screen you may see more than one port of the Web service. You just need to select one port. After selecting the port, hit ‘Next’ button.
7. It takes you step number four. In this step, you will be able to select all functions/methods that are provided by Web service. This screen gives a lot of details about the methods such as method type, port type, etc. Chose all methods that you need for PeopleSoft and hit Next button.
8. If the method that you selected above is a Synchronous Operation that it will take you directly to Step 6. If the method is Asynchronous then it will take you to Step 5 where you will be able to convert two Asynchronous messages to one Synchronous message. Hit the ‘Next’ button after you are done with step 5.
9. Now you are in Step 6 which allows you to convert Web service methods to PeopleSoft Service Operations messages. When you go to step 6, PeopleSoft automically assigns messsage names but you can change them to more meaningful names.
10. From step 6 you can be directed to either step 7 or step 8. If your web service has an asynchronous message then it takes you to Step 7. In this step you assign a Queue to your Service Operation. You can create a new queue or assign an existing one.
