title: CKAN/Jetty/Solr: ERROR 500: org/apache/tomcat/util/descriptor/LocalResolver
body: <p>I'm installing ckan onto ubuntu server 14.04 from source following this guide: <a href="http://docs.ckan.org/en/latest/maintaining/installing/install-from-source.html" rel="nofollow">http://docs.ckan.org/en/latest/maintaining/installing/install-from-source.html</a> </p>
  
  <p>The problem I'm encountering is that when I try to access solr locally I get the following error: </p>
  
  <pre><code>ERROR 500: org/apache/tomcat/util/descriptor/LocalResolver.
  </code></pre>
  
  <p>I've googled and tried changing libtomcatlib-6 to a previous version but the downgrade won't take (following this here apt-get says that the version wasn't found). Anyone have any ideas?</p>
