title: Entity class is a JavaBean?
body: <p>I am newbie for learning Java EE and still many concepts confuse me. I found an entity class looks like a JavaBean. </p>
  
  <ol>
  <li>Is an entity class a JavaBean? (please explain something here) </li>
  <li>What is the relationship between an entity class and JPA? (my understanding: is JPA a tech/API used with an entity class, which persists the data from a database?) </li>
  </ol>
