Creating a Business Service Class

After you create the web service proxy and the value object class, you create a business service class. This business service is a wrapper for the web service proxy. The business service wrapper is necessary because:

• Only internal business services that match the JD Edwards EnterpriseOne business service methodology can be called from the enterprise server.

• Most likely some conversion between the JD Edwards EnterpriseOne data types and the data types required by the web service provider will be required.

To create a business service class:

1. Add classes to the business service object.

   • Create the business service class.

   • Name the business service class.

   • Create a transaction, if necessary (IConnection object).

   • Declare a business service public method.

2. Add business service logic:

   • Map from the value object to the format needed by the external web service.

   • Create a call to the web service proxy.

   • Use business service properties.

   • Use softcoding.

   • Handle errors.

   • Format data.

After you create the business service for calling an external web service, you can create a JD Edwards EnterpriseOne business function that calls this business service. You can also create or use an existing JD Edwards EnterpriseOne application to call the business function.
