title: Metamap run local raise "Error when querying Prolog Server: Connection refused"
body: <p>I follow <a href="http://metamap.nlm.nih.gov/Docs/README_javaapi.shtml" rel="nofollow">this</a> steps to run the Metamap Java API 2014 on Linux platform
  (<a href="http://metamap.nlm.nih.gov/" rel="nofollow">Main page from metamap</a>)</p>
  
  <p>After start Metamap server, I run some main class in Metamap JavaAPI pakages, but it raises <code>Error when querying Prolog Server: Connection refused</code></p>
  
  <p>Then I check if the Metamap server is running on port <code>8066</code> by using the command: 
   <code>sudo netstat -tulpn | grep 8066</code></p>
  
  <p>but I receive nothing.</p>
  
  <p>Did anyone had the same problem before and knows solution for this?</p>
