Dear Tony, It seems you are trying to access the uploaded file (jpg, pdf, etc) via request:get-parameter()....but the file is not a parameter to the request. You need to use request:get-uploaded-file-data() within the context of multipart/form-data. This function takes the name from the file you uploaded, *not from an input*. This is accessed with request:get-uploaded-file-name() See https://exist-db.org/exist/apps/fundocs/view.html?uri=http://exist-db.org/xquery/request&location=java:org.exist.xquery.functions.request.RequestModule JPR On Mon, Dec 2, 2024 at 10:20 AM Tony Corless via Exist-open < exi...@li...> wrote: > Hello all, > > > > I am getting something slightly wrong and I’m not sure what.
