title: Cannot open the connection for the driver: org.eclipse.birt.report.data.oda.jdbc
body: <p>I got the following problem</p>
  
  <p>In Eclipse, in the Report Design Perspective , when I try to preview I get the following error: </p>
  
  <pre><code>Chart NewChart: 
  + An exception occurred during processing. Please see the following message for details:
  Cannot open the connection for the driver: org.eclipse.birt.report.data.oda.jdbc.
      org.eclipse.birt.report.data.oda.jdbc.JDBCException: Cannot load JDBC Driver class: com.mysql.jdbc.Driver. 
  </code></pre>
  
  <p>I also checked in Eclipse in the folder org.eclipse.birt.report.data.oda.jdbc/drivers and it was empty. Should it be?
  I checked the externalLibs directory, and there I have mysql-connector.jar and I do not know what to check for next.</p>
