title: Existing Spring Application to Cloud Foundry
body: <p>We are planning to move a Spring based application to Cloud Foundry.
  The application currently uses WAS server and access data sources using JNDI lookup.
  We are using spring features like MVC, AOP etc.
  I have certain questions in mind :</p>
  
  <ol>
  <li>Is it possible to switch to Tomcat and configure dataSources using Spring-cloud-connectors and possible conflicts we might run into ?</li>
  <li>Currently , datasources are configured in XML files, Should I use the same XML files or switch to annotations.</li>
  </ol>
  
  <p>Can anyone please provide some clarity over this and other known issues with this approach?</p>
