title: jmeter- what i need to do extra to connect with mysql database?
body: <p>In my JMeter test-plan, I created a thread group and added config element with JDBC connection configuration:</p>
  
  <pre><code>Url: jdbc:mysql://localhost:3306/atmdb,
  Driver class: com.mysql.jdbc.Driver
  username: ****
  password: ****
  </code></pre>
  
  <p>I also added jdbc request sampler and a view result tree listener. However after executing this test plan, I saw this error:</p>
