title: Best practice for converting ear to war file
body: <p>We are an IVR team and our application is deployed in tomcat server. We need to integrate with payment gateway.</p>
  
  <p>We have a application enterprise web archive (ear) which has jar file and few other configuration files, this application communicates with third party Payment gateway. This application is provided by a vendor, As tomcat doesn't support ear files, </p>
  
  <p>we want to know whether it is good to convert the ear file to war and deploy it in tomcat. The ear application provided to us is like a black box application. </p>
  
  <p>We are trying to hit a EJB which archived in the ear</p>
  
  <p>If it is right to convert ear to war, i would like to know the best practices so that we don't land on problem during production deployment</p>
