title: Java Spring: benefits of POJO objects
body: <p>I am learning Spring using <a href="http://www.tutorialspoint.com/spring/spring_quick_guide.htm" rel="nofollow">this</a> tutorial. I am unable to get my head around the following excerpt from it:</p>
  
  <p><em>Spring enables developers to develop enterprise-class applications using POJOs. The benefit of using only POJOs is that you do not need an EJB container product such as an application server but you have the option of using only a robust servlet container such as Tomcat or some commercial product.</em></p>
