Description

Per the javax.activation.DataSource API

/**
     * This method returns the MIME type of the data in the form of a
     * string. It should always return a valid type. It is suggested
     * that getContentType return "application/octet-stream" if the
     * DataSource implementation can not determine the data type.
     *
     * @return the MIME Type
     */
    public String getContentType();

So cxf AttachmentDataSource should also follow this. For the case that the incoming soap message with attachments, if the MIME part doesn't specify a content-type, use the general
"application/octet-stream"
