title: SolrCore Initialization Failures on JBoss 7
body: <p>I have deployed a stand alone instance of <strong>Solr 5.2.1</strong> on <strong>JBoss 7</strong> using these very simple instructions from the Solr wiki:
  <a href="http://wiki.apache.org/solr/SolrInstall" rel="nofollow">http://wiki.apache.org/solr/SolrInstall</a> and
  <a href="http://wiki.apache.org/solr/SolrJBoss" rel="nofollow">http://wiki.apache.org/solr/SolrJBoss</a></p>
  
  <p>I have set my <strong>solr.solr.home</strong> (which points to the folder copied directly from example/example-DIH) this folder has 5 sub folders (db,mail,rss,solr and tika) I have made no modifications to any of them, each has conf and some have lib folders, which I assume is what Solr is looking for....</p>
  
  <p><strong>solr.data.dir</strong> I have not set in my environment variable as I don't know where it should point to? I had planed to point it to a coreName/data once I have everything running, but that means I can only have 1 core?</p>
  
  <p>Solr does start and I can see the console, however I get the following Initialization Failures:</p>
  
  <pre><code>tika: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'solr.DataImportHandler'
  
  db: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'solr.DataImportHandler'
  
  mail: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'solr.DataImportHandler'
  
  rss:
  org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'solr.DataImportHandler'
  
  solr: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error loading class 'solr.DataImportHandler' 
  </code></pre>
  
  <p>Clearly Solr is looking for these libraries, I just don't know where they are or how to tell Solr to look in the 5 folders described above, I had hoped the war file would have all the necessary libs it needed.</p>
  
  <p>Unfortunately I am not sure what needs to be configured / added next and the wiki seems to lead one to a point and then just stop short of explaining additional configuration steps.</p>
  
  <p>Can somebody point me in the correct direction to go from here?
  Also is it possible to secure the admin console (Jboss7 - Solr5.2.1)</p>
  
  <p>Thanks
  Marc     </p>
