Release 10.1A: OpenEdge Development:
Web Services

SOAP message formats

The OpenEdge implementation of Web services uses the request/response model for invoking and handling the results from operations on the Web service. The client sends a request message to the Web service, and the Web service returns a response message back to the same client.

Usually, client interfaces expose this request/response pair as a single object method. When the client executes the method, the underlying interface sends a SOAP request message containing any method input parameters and receives a SOAP response message containing any method output parameters and any return value.
