Re: [stp-dev] Discussion on policy support in STP
|
Hi Jerry,
Currently the XEF Policy Editor does not use Neethi yet. Its internal
representation is actually highly based on the XML Schema definitions of
the policies and for this it uses the Xerces XML Schema API
(http://xerces.apache.org/xerces2-j/javadocs/xs/index.html).
I think at the moment the easiest integration would be on top of the
actual XML (WS-Policy) content. The XEF Policy editor currently has 2
tabs, one with widgets and another one with the XML text. There are
conversions from one to the other which get triggered when a user flips
the page.
If a conversion to/from your WTP-based policy editor from the plain XML
would be added (or maybe its already there?), we should be able to run
both editors (plus a plain text page) in a single multi-page editor,
correct?
Cheers,
David

Hi David,
we're using the implementation of policy intersection in Neethi. We
thought about using a model based on Neethi, but did not get around to
that yet.
Maybe this is the easiest way to get to a common model beneath the XEF
editor and the Sopera one. Do you think moving to a Neethi-based model
would be feasible for the XEF editor?
regards
Jerry

I don't think XEF policy editor has those same restrictions, however
it does not yet support all of the WS-Policy formats. The XEF editor
currently only supports policies nested in <wsp:All/>, e.g:
<wsp:Policy xmlns:wsp="http://www.w3.org/ns/ws-policy";>
<wsp:All>
<acme:Logging xmlns:acme="http://www.acme.com/xsd/2007/08/logging";>
<file filename="myService.log" rolling_file="true" />
</acme:Logging>
<acme:Security
xmlns:acme="http://www.acme.com/xsd/2007/08/security"; />
</wsp:All>
</wsp:Policy>
On the policy model, did anyone consider Apache Neethi
(http://ws.apache.org/commons/neethi/index.html)? It provides an API
on top of WS-Policy documents. This might provide something in the
context of a Policy model...
Cheers,
David
