title: How to fix java IOException: Can't find resource 'solrconfig.xml' in classpath?
body: <p>I was trying to install Apache Solr 4.0.0 with apache Tomcat, but it is giving an error like this: </p>
  
  <blockquote>
    <p>SolrCore Initialization Failures
    collection1: java.io.IOException:java.io.IOException: Can't find resource 'solrconfig.xml' in classpath or 'solr\collection1\conf/', cwd=C:\apps\tomcat-solr\apache-tomcat-7.0.35\bin</p>
  </blockquote>
  
  <p>There are no SolrCores running. 
  Using the Solr Admin UI currently requires at least one SolrCore.</p>
  
  <p>After this I have installed apache solr 3.6.2 and it working perfectly well. I still cannot understand why i am not able to use solr 4.0.0 with the same server configuration.</p>
  
  <p>I hope you will be able to tell me the mistake i have committed.</p>
