Hello again, I have looked if there is an item without submitter, with sql
query:
select * from item where submitter_id not in (select eperson_id from eperson)
or submitter_id is null
But there is no record.
I have run the [dspace] / bin / dspace oai import -o -c -v command
and was executed successfully.
restart tomcat, and entering the address (http://localhost/oai/request), it
displays a blank page and the catalina.out file shows the following error
org.apache.solr.client.solrj.impl.HttpClientUtil createClientINFO: Creating new
http client,

have to fix this error.
thanks in advance
Hello, We have migrated from version 1.6 to version 4.2 DSpace, DSpace runs
oracle, the jspui context and solr working properly. But when starting the OAI
context, it displays the following error when accessing the URL:
