Hi everyone, I and @zbenta are having some issues with OAI-PMH endpoint in our dataverse instalation at https://repositorio.polen.fccn.pt/oai , the server responds with an internal server error and the logs for payara shows as follow. Any ideas?

Hi! Based on https://repositorio.polen.fccn.pt/api/info/version it looks like you're running 5.13.

So that's https://github.com/IQSS/dataverse/blob/v5.13/src/main/java/edu/harvard/iq/dataverse/harvest/server/web/servlet/OAIServlet.java#L250

And https://github.com/gdcc/xoai/blob/xoai-5.0.0/xoai-data-provider/src/main/java/io/gdcc/xoai/dataprovider/request/RequestBuilder.java#L119

https://repositorio.polen.fccn.pt/oai?verb=ListMetadataFormats works. Is it just that you were missing a verb?

:man_gesturing_ok: We could swear that we did not have to pass any extra arguments to the endpoint. Thanks @Philip Durbin for the help.

Sure! I don't know how OAI-PMH is supposed to work, if it's supposed to return a 404 if there's no verb.

"OAI-PMH repositories may employ HTTP Status-Codes in addition to "200 OK"."

So I guess it's up to us. "May".

Simply throwing a ServletException in OAIServlet was maybe not the best choice in hindsight

view this post on Zulip Oliver Bertuch (Oct 27 2023 at 12:08):

(Throwing such an exception will always trigger an error 500)

I would prefer a non-JSF page for the 404 at /oai ... https://demo.dataverse.org/oai for example. But I guess JSF is going away (thank goodness).

view this post on Zulip Oliver Bertuch (Oct 27 2023 at 12:09):

IMHO we should move that servlet to a JAX-RS endpoint

view this post on Zulip Philip Durbin 🚀 (Oct 27 2023 at 12:09):

Sure, sounds good. SWORD too?

This is starting to feel like it belongs in #dev :grinning:

view this post on Zulip Oliver Bertuch (Oct 27 2023 at 12:10):

Probably. IIRC SWORD did have some support for this already, but not sure.

Well what we should say here: @zbenta @César Ferreira if you want the behaviour changed, please open an issue. A link to this conversation would be much appreciated!
