[oXygen-user] eXist-db in <oXygen/>?

[David Birnbaum]

Dear oxygen-user list,

I've constructed an XQuery script for eXist-db that uses the function
request:get-parameter(). It works as expected in eXide. I have established
a data source connection between <oXygen/> (XML Editor 21.1, build
2019120214, running on MacOS Mojave) and eXist-db (5.0.0) running on
localhost, and I can open, edit, and save XQuery scripts from inside
eXist-db within <oXygen/>, from which I conclude that the connection is
live. Since <oXygen/> apparently cannot use the eXist-db data source
connection for debugging, instead of using the <oXygen/> XQuery debugger
perspective to run the script I configured a transformation scenario where
I specify the localhost eXist-db connection as the Transformer. When I run
this script, I get the following error message from <oXygen/>:

err:XPDY0002 Variable $request is not bound to an Java object


The function is used in a line that reads:

declare variable $story_id as xs:string := request:get-parameter('story',
'x');


I thought at first that the error might be because the "request:" namespace
prefix was not declared and bound (eXist-db declares it implicitly), so I
added an explicit namespace declaration for it:

declare namespace request="http://exist-db.org/xquery/request";


The error remains. The entire XQuery script is below; it retrieves
information from a TEI document, based on a user-supplied resource name, if
the document exists and returns an error message otherwise.

Can someone please help me identify what I have apparently misunderstood
about running XQuery scripts in an <oXygen/> transformation scenario using
eXist-db as the XQuery transformer?

Sincerely,

David
