This article describes how to use the Web Service service in processes to invoke services that require file attachments as input values. This article also describes how to specify the format in which file attachments are returned by LiveCycle ES web services.
For example, service input and output variables of type document are represented in SOAP messages as file attachments. To provide input document values, the SOAP message includes a file attachment. Response messages include file attachments when web services have output variables of type document.
Files can be attached as MIME or MTOM attachments, base64-encoded text, or using the URL of the file:
- The SOAP message and the configuration of the Invoke Web Service operation is different for each type of attachment. (See Configuring the web service request message.)
- If you are invoking a LiveCycle ES web service that returns a document value, you can specify the method that is used to attach the file to the SOAP response message. (See Configuring the web service response message.)
Note: Web services that are provided by LiveCycle ES do not support MTOM attachments.
