Development of Calculator Integration | SOAP Connection

 Use Case : 
In this blog we will develop a Basic Routing Integration which will do summation of two numbers.
Suppose we will pass 5 & 6 as Input of Integration, Output we will get is 11.

*Note : you can click on any image to zoom out.

Complexity: None

  • Calculator SOAP Connection (please see previous blog to know how to create this connection in OIC)
  • SoapUI - 5.5.0 Tool to test this integration (you can download it from google, make sure that you download the latest version 5.5.0 or Upgraded version then 5.5.0)

lets see the development steps in detail:

STEP 1 : In the navigation pane, click Integration then click Create

STEP 2 : select Basic Routing and enter the Integration Name and then click Create

STEP 3 : Drag & Drop the Calculator Connection (which we have created in previous blog) from right hand side connection pane to left hand side Trigger part of Integration (as shown in below image)

  • Write end point name & then click Next (You can give any meaning full name)
  • Select the operation add & the click Next
  • Skip this page, just click Next
  • click done

STEP 4 :  Now drag & drop the Calculator Connection (which we have created in previous blog)to right hand side of integration (i.e. at Invoke) as shown in below image

  • Write the endpoint name & the click Next (You can give any meaning full name)
  • select the below options & the click Next :
                                Select the Port : CalculatorSoap
                                Select the Operation : Add

  • Skip this configuration header page, just click Next
  • Click Done

STEP 5 : Click the upper mapper to edit, as shown in below image

STEP 6 : Map the columns as shown in the below image and then click to Validate and then click Close

STEP 7 : Similarly click the lower mapper to edit

STEP 8 : Map the columns as shown in below image and then click Validate and then click Close

STEP 9 : In the upper right corner, click the hamburger menu and then click Tracking

STEP 10 : Map the *intA (left hand side)  to Primary(right hand side) and then click Save

STEP 11 : click Save and then Close the integration. Your Calculator integration completed.

in next blog, we will see how to test this integration.....thank you !


  1. Excellent brother Please bring more blogs related to OIC.

  2. Great help Kabir.. exciting..wl check next integration POCs also.

  3. What if I want to expose all four operations Add, Subtract, Multiply and Divide in trigger to expose the Integration as SOAP service with all four operation and user can select and invoke based on their choice.

    1. for that you need to create a SCHEMA that is cable to handle all these 4 operations and then select the same schema while configuring SOAP adapter. But creating the schema itself is little challenging😋 , I can say this because the same coding I have did to get my first project in Infosys 😅...

  4. But will that help as you mentioned in 3rd point of Step 3 here that we need to select particular operation for every created trigger...so how is it possible to expose all operations with the trigger...like we can do in SOA 12c to expose different operations of SOAP service with one endpoint.

    1. it is possible... just do some engineering with SCHEMA .....

  5. Actually my doubt is when we are selecting any particular operation for trigger... it is perfectly fine to select any particular operation for invoke as we need to perform that specific task but if we are selecting any one operation for trigger also then it is limiting user to perform only that particular task but in real requirement scenario it will not be good solution to expose different endpoint for each operation user wants to perform....this is limiting the benefit provided by wsdl and SOAP


If you have any doubts, Please let me know.
