Enabling SOAP Attachments for a Web Service Descriptor
Before enabling SOAP attachments for a web service descriptor, configure the watt.server.SOAP.MTOMThreshold property with the appropriate value. This property specifies the field size, in kilobytes, that determines whether Integration Server sends base64binary encoded data in an outbound SOAP message as a MIME attachment or whether it sends it inline in the SOAP message. For more information about this property, see webMethods Integration Server Administrator’s Guide.
If you want to stream MTOM attachments, you have to do additional configuration. For more information about the configuration required to enable MTOM streaming, see the Web Services Developer’s Guide.
