The Web Service Request agent works in the same way as a Service Requester, or a client, that sends a Web Service request to a server, where a certain service is available. The response, if any, can then be routed into the workflow.

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.

The Web Service Requester - asynchronous operation

To configure the Web Service Request agent:

  • Open the Web Service Request agent configuration dialog from a workflow configuration: Right-click the agent icon and select Configuration..., or double-click the agent icon.
SettingDescription

Web Service Profile

Click the Browse button and select a predefined Web Service profile.

Response Timeout (ms)

The timeout value specifies the maximum allowed response time in milliseconds (ms) back to the Request agent after a request is sent to the service. If the response time is exceeded, the Request agent times out and an error message is logged in the System Log. The WSCycleUDR is routed out from the agent with the errorMessage field set.

Support CDATA encapsulated content

Select to always send content encapsulated with CDATA tag without escape characters in the SOAP message.

Note!

The content must be completely encapsulated by CDATA tag for correct output. No leading or trailing characters are allowed, for example:

data = "<![CDATA[This will be output as CDATA]]>"

Note!

To be recognized as carrying SOAP error information, a SOAP message MUST contain a single SOAP Fault element information item as the only child element information item of the SOAP Body. When generating a fault, SOAP senders MUST NOT include additional element information items in the SOAP Body. A message whose Body contains a Fault plus additional element information items has no SOAP-defined semantics.
