This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
In addition to increased productivity, another business benefit of using POJOs+lightweight frameworks is that you no longer need an EJB container and you might be able deploy your application in a simpler and/or cheap web container-only server such as Tomcat or Jetty.
I hope this helps.
