wm.tn.doc:addContentPart

bizdoc	Object The document to which you want to add a new content part. The document must be an instance of com.wm.app.tn.doc.BizDocEnvelope.
partName	String The name of the new content part (for example, “OrderAttachment”).
partBytes	Object The content of the part you are adding to the document. The data type of partBytes must be byte[].
partStream	Object The content of the part you are adding to the document. The data type of partStream must be java.io.InputStream.
mimeType	String The MIME type of the content part you are adding (e.g. “text/plain” or “application/pdf”).
partIndex	String (optional) The position of the content part in the document's existing array of parts. The beginning position of the content part is 0.

updateCount

String The number of documents that the service updated. The values indicate:

1 The service added the new content part to the document.

0 The service did not add the new content part to the document.

You must supply either partBytes or partStream to the addContentPart service, but not both. If partStream is supplied, Trading Networks will determine whether the new content part is large, and will handle it appropriately. If partBytes is supplied, Trading Networks always considers the new content part to be small, regardless of its actual size. For information about large document handling, see webMethods Trading Networks Administrator’s Guide.
