title: Spring Boot GS: ComponentScan and ClassNotFoundException for ConnectionFactory
body: <p>I'm playing sur the Spring Boot getting started guide but the auto configuration fails and I get:</p>
  
  <pre><code> java.lang.ClassNotFoundException: javax.jms.ConnectionFactory
  </code></pre>
  
  <p>It seems it's due to the location of the Application class. Where should it be located? At the top-level package (src/main/java) or in a specific package?</p>
