How to create Outbound Web Service in Siebel?

Today, lets talk about how we can invoke an Outbound Web Service from Siebel. In the last post we learned how to test the WSDL using SOAPUI and I will use the same WSDL today (CurrencyConverter.wsdl) as the sample wsdl in this post.

1. Import the WSDL into Siebel Tools.
Create New Object. File Menu -> New Object -> EAI -> Web Service



Select the WSDL file path



Business Service will get created with name "CurrencyConverter" and its method "CoversionRate"



ConversionRate method has got its Input/Output Arguments. The point to be notice here is the Integration Objects i.e. "ConversionRate" and "ConversionRateResponse". These are the external integration objects which defines the Request and Response XML of the Web Service.



If you query for Integration Object (Input): "ConversionRate", it will look like this:
and these are the two Input arguments of the Request XML of the Web Service.



Similarly, the Output IO will have a single output argument:



2. Create the UI. (Applet based on Opportunity BC)



3. Create Workflow to get the response from Web Service.






4. Call the Workflow from button click. To do this just create a BC User Prop on Opportunity BC

Named Method 1 : "Invoke", "INVOKESVC", "Opportunity", "Workflow Process Manager", "RunProcess", "'ProcessName'", "CurrencyConverter"

Where "Invoke" is Method Invoked from button on the opportunity applet.

5. Compile the objects and test.



After button click:




I am assuming that you are connected to internet while doing this test and this is how you can play with the live web service.

How to test a WSDL if it is working or not?

No matter if you are working in Siebel or not, if you are going to implement any Outbound Web Service, the first thing you wanna check if the WSDL file received from the 3rd party is working or not before you actually consume it and start the development.

Same is the case with Siebel Tools, you require to consume it in Siebel tools which will result in creation of Web Service (which is nothing but the business service of Class: CSSWSOutboundDispatcher) and its corresponding Integration Objects.

So, the best way is to have a 3rd party tools to quickly verify the response from the other system. I have came across lot many tools which solve this purpose but my favourite is SOAPUI and I really find it very handy for this purpose.

This post is related to the very first step that you do while creating the outbound web service. I have picked one WSDL freely available on "http://www.webservicex.net/WS/default.aspx"

Now, lets see how to do it step by step:

1. Save the WSDL from the following link:
http://www.webservicex.net/CurrencyConvertor.asmx?WSDL



2. Get the SOAPUI tools, available at the below link:
http://www.soapui.org/

3. Open SOAPUI and go to File Menu -> Preferences and make sure following check boxes should be unchecked.



4. Now open the WSDL, that you have saved in Step 1. File Menu -> New SOAPUI Project OR Press Crtl N





5. You will see "Currency Converter" Web Service and its associated method in the left (Navigator) panel. Double click on "Request 1". It will bring up the SOAP Request / Response page in the right panel. The request XML will look like this:



6. Input the necessary values in FromCurrecny and ToCurrency tags of the request XML and hit the Go Button. For Eg:



7. Here is the response XML I received:



8. This confirms that WSDL is correct and working fine.

We will see in the next post, how to implement an Outboound WebService in Siebel.
