Problem

-- A XML message fails to be sent out via Web Services protocol

-- Error message is:

Error packaging Message
org.apache.axis2.AxisFault: Error in extracting message properties

-- The payload contains a DOCTYPE declaration

Resolution

** Per default a Web Services payload is being sent in the SOAP body

** If payload is part of the SOAP body, it will be integrated into the SOAP message.

** DOCTYPE declaration cannot be preserved as part of the SOAP body and SOAP recommendation actually forbids the usage of DOCTYPE:

SOAP Version 1.2 Part 1: Messaging Framework

"The XML infoset of a SOAP message MUST NOT contain a document type declaration information item".

To solve the issue, the payload must be sent as an attachment. This can be changed on a per partner basis:

1. In the UI, go to Trading Configuration -> Show collaboration settings
2. Select the community -> partner on the left side (if partner is missing, use "Specialize collaboration settings for a partner" to add partner)
3. Enable "Set sending rules for the Web services message protocol"
4. For the "Payload location:" select "Attachment"
5. Save
