xupdate update in cocoon

[Don Saxton <ds...@pacbell.net>]

Hi

I have a good start in putting xindice 1.1b together with cocoon 2.04 (jdk
1.4 tomcat 4.1.18), but I am really stuggling with Xupdate.

I got this far by using the experiences of several people on this list.
Thank you greatly. Frequently  I read that others get xupdate to work, so I
am hoping that someone can help me over the last hurdle.

Below are xupdate query that I input to the cocoon transformer
XMLDBTransformer and the result.
With xmldbgui I can successfully xupdate with the modifications node set of
the update query below.

The query side works well and I am able to snag a fragment from a document
or a document from a collection. I can do it through cocoon, xmldbgui,
xincon, and almost with "the ugly debug tool" (can't glue the xpath query
onto the http collection request, but it's still a keeper).

One suspect is xmldb-api-20021118.jar.  I could not find
xmldb-api-20021126.jar or how to get to xmldb cvs. My other suspect is
XMLDBTransformer which seems to require an oid attribute eventhough a query
of type="update" is documented as not needed. It doesn't seem to matter what
the value of oid is. Related to these is that I can't find documented (well,
meaningfully documented) the difference between these two:

XUpdateQueryService.update(String document)
XUpdateQueryService.updateResource(String key, String document)

Thanks for everything

Don
