title: Problem indexing files in Solr on Ubuntu
body: <p>What I want to do is index some documents in Solr and know how it works. I have installed Solr and Tomcat and can see Solr Admin UI at localhost:8080/ solr/ admin/
  Now, I want to add some documents to the index, may I know how to proceed further? I find very less documentation on Internet regarding this.
  In the tutorial <a href="http://lucene.apache.org/solr/tutorial.html#Indexing+Data" rel="nofollow noreferrer">http://lucene.apache.org/solr/tutorial.html#Indexing+Data</a> they asked to run java -jar post.jar solr.xml monitor.xml command but after running that I get connection refused error as it is jetty. 
  After installing jetty I tried telnet: I get "Connection refused" error</p>
  
  <p>I am not able to understand what the problem is.</p>
