[Dspace-tech] Exception: Server at http://localhost:8080/solr/search returned non ok status:404, message:Not Found

[Hassan Bhuiyan]

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.

Hello,

it seems like a Solr's problem.

A solution to your problem is to copy the folder "[dspace-installation-directory]\webapps\solr" to "C:\Program Files\Apache Software Foundation\Apache Tomcat (your version)\webapps" (or wherever is the Tomcat's installation directory).

Another solution is to locate the Tomcat's server.xml file and change the

<Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true"> 

with something like that 

<Host name="localhost"  appBase="/c:/dspace/webapps" unpackWARs="true" autoDeploy="true">

Then you can test if Solr is "working" @ http://localhost:8081/solr/

Hope it helps.

Teo.
