title: Q: I can't start Database connection in Eclipse
body: <p>I try about half a day to start database server in Eclipse without effect... </p>
  
  <p>I've the newest Eclipse MARS. I opened the view of <code>Data Source Explorer</code> and right-click on the <code>Database Connections</code>, choose <code>New &gt; Derby</code> and <code>Define new driver</code> of <code>Derby Client JDBC Driver 10.2</code> and select <code>JAR List &gt; ADD JAR/Zip</code>, I downloaded the driver to derby <code>version 10.2.2.0</code>. </p>
  
  <p>I set...</p>
  
  <p><code>Database: sample
  Host: localhost
  Port number: 1527
  User name: sa
  Password: sa</code></p>
  
  <p>..and try to run the new created server and then ERROR pop-up with information </p>
  
  <pre><code>Could not connect to New Derby.
  Error creating SQL Model Connection connection to New Derby. (Error: java.net.ConnectException: Error when connect with server localhost at port 1527 with message Connection refused: connect.)
  </code></pre>
  
  <p>Anyone have problem with that ? I try the same with other type of databse (I try MySQL, downloded too the newest drivers and I have the same error).</p>
