Hi I am trying to upgrade from DSpace1.6.2 to DSpace 4.1. Everything went okay except index-discovery. I can see community and collection lists and log in to DSpace administrator account and see items in the pool waiting to be archived.
Problem: Homepage shows message "Internal Systems Error" and does not show the item lists. It will be helpful if someone can help me please. Note: I tried with rebuild and fresh installation again but still the problem remains same. Note: I don't see anything directory called "/solr/search" directory in my TOMCAT. Regards Hassan Bhuiyan Brunel University, UK I get following error while executing index-discovery -f ( when TOMCAT is running)
