This section describes the Web Service profile and agents. The agents are collection and processing agents for real-time workflow configurations.

Prerequisites

The reader of this information should be familiar with:

  • Web Services

  • WSDL

Web Service is a software system that supports interaction between computers over a network. The Web Service agents communicate through SOAP in XML syntax, and use WSDL files.

The Web Service agents support:

  • Web Service Interoperability Organization Basic Profile 1.1

  • WSDL 1.1

  • XML 1.0

  • SOAP 1.1

  • Partial support of Web Service Security 1.1

  • HTTP 1.1

  • HTTP Basic Access Authentication

  • Updatable Authorization header per request

  • HTTPS

  • IPv4 and IPv6

The mustUnderstand attribute is only supported in Web Service Security headers. 

To enable Web Service transactions in :

  1. Define a Web Service (WS) profile or profiles.
  2. Include the Web Service agents and their configurations in a workflow.

Web Service Profile

In the WS profile you specify a WSDL file that mainly includes the following parts of a Web Service definition:

  • XML Schema: Defines information about the service either directly or via an XSD-file

  • WSDL: Communication relevant information

  • Binding elements: supports only SOAP bindings

The WS profile can include more than one WSDL file references.

The WS profile is loaded when you start a workflow that depends on it. Changes to the profile become effective when you restart the workflow.

Saving a WS profile that is assigned with a WSDL file, maps data types that are specified in the WSDL Schema section as UDR types for the workflow. For further information, see Web Service UDR Type Structure.

The Web Service Agents

There are two Web Service agents that you can include in real-time workflows in the workflow configuration dialog:

  • The Web Service Provider agent

  • The Web Service Request agent

Web Service Provider Agent

The Web Service Provider agent works in the same way as a Service Provider, or server, in the sense that it receives requests from a client, or clients, and transfers the requests to a workflow.

In a synchronous operation, when the collection agent receives a reply back from the workflow, it delivers the response to the requesting client.

In an asynchronous operation the collection agent does not receive any reply, and therefore does not respond the client.

The Web Service Provider - synchronous operation

Web Service Request Agent

The Web Service Request agent works in the same way as a Service Requester, or a client, that sends a request to a server, where a certain service is available.

In a synchronous operation, when the processing agent receives a reply, it delivers the reply to its configured output.

In an asynchronous operation, the requester does not receive any reply and does not deliver one, either.
