title: A portlet application should be deployed as war file or ear file
body: <p>In the websphere portal environment, how is a portal application consisting of many portlets supposed to be deployed? As a .war file or a .ear file? </p>
  
  <p>I see that on environments that do not have RAD installed, it is deployed as a .war. But on the dev machine which has RAD installed, it is deployed as an EAR project. Is there a best practise around this?</p>
