Subject RE: [OT] What layer does an XSL transform belong to
Date Tue, 03 Jun 2003 14:21:57 GMT
honestly, it depends upon your approach.

if you see transformation from callback perspectives, they should be part of
presentation later (may be as part of the taglibs) but if you have servlets
that does generates the XML as well as XSL then runs the
XMLTransformer.transform() (could be filtered) then it should be 1 layer
above presentation.....correct me if i am wrong.

|
|Hey all,
|
|A bit philisophical I suppose, but we've integrated some
|legacy apps into a Struts application, and they return their
|data as an XML document.
|
|In a previous version of the app, the JSP made the legacy
|call (gakk!), and then performed an XSL transform to display
|the info to the user. (I didn't write it :)
|
|I'm trying to migrate things towards their proper places, and
|my question is where (if anywhere) the XSL transform belongs.
|
|Ideally, I would either call the legacy app from within a
|Action, or pushed down yet another  layer behind some
|model call.
|
|But if I did a model layer, then I'd probably transfer the data
|from the XML document to a Java model object and then
|transfer data from the model to a form via the Action and let
|the tag libraries take it from there.
|
|I don't have the luxury of a rewrite, so trying to incrementally
|migrate and just not sure where the XSL transform should
|land (or at least roost).
|
|your insights would be appreciated
|
|regards,
|
