Re: [wsbpel] Issue - 90 - Proposal to vote

Kristofer, the use case for having an external document that is part of the
business process is not clear to me. Why is this not a literal residing
inside of the process definition. In addition, such document references
would create a new problem as I see no obvious way of recognizing changes
of the external artifacts.
Kind Regards

Hello all,

Here is a proposal to vote for issue 90 (
http://www.choreology.com/external/WS_BPEL_issues_list.html#Issue90):

-----------------
Proposed solution:

Introduce a new form of the <from> element:

<from location=”document-location” query=”queryString”?/>

The query attribute has the same semantics as the normal query attribute on
the <from> element, i.e. it must be an absolute location path and select
exactly one node. If no query is specified, the root node of the XML
document is selected. The document-location is a URL (as defined in RFC
2396) that refers to an XML document, and in the case that the XML document
is not valid and/or a single node cannot be returned, a selectionFailure
fault should be thrown by a compliant implementation. The document that is
retrieved from the URL is considered static in the same way the business
process definition is considered static during execution. Furthermore, the
external document is considered part of the business processes that
reference it, and conversely, the business process definition should not be
considered complete or valid without the external document. A change in the
external document should be treated in the same way as a change in the
business process definition.

This <from> form can be used in conjunction with all the <to> forms.

Kristofer Agren
