Service Providing 

Purpose

Whenever a Web service is called, the service provider receives the request message of the service consumer. The consumer sends the response message back to the service user.

Process Flow

This process is used to execute a called Web service at the service provider.

       1.      Receiving the Request Message

The message of the service user is sent to the service provider.  The message contains the parameters that are the basis for the query of the service user.

       2.      Executing the Proxy

When the request message is received, this invokes a suitable protocol on the side of the service provider. The received parameters are passed to the application in the appropriate format.

       3.      Sending the Response Message

The application sends a response message. The service user proxy transmits the returned data to the application. 

Result

The message from the service user was received and processed by the service provider. Then the return data was sent back to the service user.
