What is the default address of Solr Server (Solr 4.0) for use from a SolrJ client

Question

I'm trying to connect with Solr Server from a SolrJ client, but it gives an HTTPResponse Exception.

Here's my code:

SolrServer server = new HttpSolrServer("http://"localhost":8983/solr/");

Here's the exception:

java.lang.NoClassDefFoundError: org/apache/http/NoHttpResponseException:

Does Solr have a default address? Where can you find it?

"localhost" has been quoted only in my question, but not the actual code. — EternallyCurious, Apr 21 '13 at 08:15
Over localhost on Tomcat - no config changes really. Everything's pretty default. — EternallyCurious, Apr 21 '13 at 12:11
Solr does not have a default port but is just an web application.Is tomcat running on port 8983 ?? 8983 is the default jetty port. For Tomcat its 8080. Please check the configuration or the logs for the port. — Jayendra, Apr 21 '13 at 18:16

I am not familiar with SolrJ - but the endpoint seems to be missing the core name to me.

You would need to point your Solr client to a particular core.

The URI for the core would look like this (for reloading core command)

http://localhost:8983/solr/{{solrCoreName}}

The admin UI should be accessible at

http://localhost:8983/solr

yeah actually I've done that already. This is my actual address - http://"localhost":8983/solr/collection1/ - where collection1 is the core name – EternallyCurious Apr 21 '13 at 15:11
are you able to see the admin page coming up ok? – Srikanth Venugopalan Apr 21 '13 at 15:54
Yeah, the admin page shows up fine. I've to go to it through Tomcat admin at localhost:8080. – EternallyCurious Apr 22 '13 at 03:03
that's strange - is tomcat routing the traffic through port 8080? Can you try setting your client to point to `http://localhost:8080/solr/collection1/` ? – Srikanth Venugopalan Apr 22 '13 at 04:23
I tried that earlier too and I just tried it again, just now. Same exception. 8080 is just for the admin console, not the client! – EternallyCurious Apr 22 '13 at 06:37
Actually turns out 8080 is for both, but its still not working – EternallyCurious Apr 27 '13 at 05:15

By default, Solr will start on port 8983. That can be changed though. You can change that for example in the solr.in.sh file using the SOLR_PORT property.
