Hi Helen, David, Import statements within eval expressions start looking for files from modules-root as specified in the app server. You need xdmp:get-request-path to make it work, there are currently no alternatives, except passing in the request path as an external var when calling the xdbc server.
Xdmp:apply and xdmp:invoke are indeed the best alternatives for relative paths, but the xdmp:apply doesn't make the function run in a separate transaction. I personally dislike having many main modules, but unless you are willing to send the request path as external var yourself there are only little alternatives..
